      when
      the cabin heat valves are shut, the dumped hot air is directed down

      I am having a hard time visualizing what you installed.  Are you using 
      the koolmat to direct the hot air down instead of towards the engine.  
      In this case the koolmat is working as a plenum and not insulating the

The 1" was something I had lying around the hangar. No issues with the fiberglass and the heat.I made the reducers by carving some styrofoam and wraping it with duct/mylar tape and then glassing over it.

I just followed the standard plans and crushed the large scat tube to fit the space. After 5 years no problems with chafe or perforation. It is ugly, but it works. Deems' installation is obviously 1st class, but a bit of extra work. I would say two far more important issues are : 1) the cheap aluminum air distribution boxes on the firewall supplied by Vans. I suggest using only the excellent (after market) fire resistant stainless steel steel boxes. Could save your life. 2) Also, if I were building again, I would improvise easier access to the fuel system (in the tunnel) - pump and filter - for easy servicing. Servicing the fuel filter is a real pain. Top and side access portals would facilitate servicing. -------- See you OSH '15 Q/B - flying 5 yrs.

Hi Agree with David's comment on the fuel filters. One of the "legacy" items from my earlier filters install was placement of fuel filters in the wing roots. I was able to install two Earl's Performance filters - one in each wing root. They are user serviceable and easily accessed simply by removing the wing root cover panel. Now I don't have to contort myself to get at them as I would if they were in the tunnel. Regular cleaning, especially when first flying, is a must. There can be a lot of accumulated crud when building. I also installed an access panel on the pilot's side wall of the tunnel for easy access to the aux fuel pump.

Linn These are what I used : http://www.summitracing.com/oh/parts/ear-230206erl I flow tested them at something north of 50 GPH so they are well suited to our application (IMHO). The screens are easily removed and cleaned. I have done so several times. When I first was flying, I had to install gascolators to meet inspection requirements. These I had in the wig roots and the filters were under the seat. Accessing them was a real pain. I wanted easy access. I certainly didn't want them in the tunnel. When I received permission to remove gascolators, I moved the filters to the wing roots. Much easier access (5 minutes and they are both out). Also, rather than ruin a solid line from the tunnel to the fuel tank, I ran the line to a bulkhead minutes on the fues sidewall. It was easy to mount the filter between this and the tank outlet.

Hi Kelly I went to a local auto supply shop and got some edge trim and put that on the inboard edge of the wing root faring. I think it looks quite nice. I can in a 50' foot roll and cost perhaps $40. I don't have the name, but can get it when I am at the hanger next.

Hi As requested by Patrick, here is a pix of of my wing root fuel filter. I misspoke in my earlier post when I said I used a bulkhead union for the line. I didn't as I had a connection at the filter I could break. It is hard to see but I used a 90 degree AN fitting to attach the top of the line to the filter. Lest anyone ask, the other line to the tank is a return line, another Subie legacy item that proved useful.

Subject: Wing root fairings
Date: Mar 26, 2015
I used the same rubber channel that is used on the wing root for RV-8s and such (same material as used on the bottom of the Horizontal Stabilizer, just longer) I purchased the material from Van=99s. Like Jesse says, no need for this along the fuselage skin where there is a bracket to screw down the root fairing. Not installing this trim made the leading edge to fuselage transition look unfinished. When you do this you=99ll need open the leading edge to fuselage gap perhaps 1/8=9D to =C2=BC=9D to provide room for the channel. Also use a little black RTV in the channel that slides over the root fairing to make sure it does not work itself out and start flapping on the side of the fuselage (this was a rude awaking during my third flight in the RV-8A). Put the RTV in the channel then install on the leading edge fairing such that the RTV sets up with the channel in place.

Yep, you need to create room for it between the cover and the fuselage skin. I don't have any RTV on it, and it stays on fine even where there no support angle underneath, just need to make sure the gap is not too big. With the J shaped rubber I used there's not a lot of rubber sticking out, maybe only 3/16.

I used some edge guard that looks like this. http://www.trimlok.com/prod/Edge-Guard/Edge-Trims/All-Product-Categories_120/Edge-Guard_119.aspx I got it at a local automotive store up in Minnesota. It fits snugly on the edge with no adhesive required. No need to trim the metal to make it fit, either. I also put it on the edge of my glareshield, which I painted flat black rather than covering it. The material was very inexpensive, and seven years and counting it still looks great. Sounds like the same type of material that Les used.

Bob, I always remove the fitting on the leading edge and pump from the trailing edge until i see movement of grease at the open hole. I then put the plug back in and do the other blade. Some say just 2 pumps per fitting, but I don't know if that is without removing the fittings or with them out.

Award for most accurate response. Believe it or not you can over lubricate even with a zerk removed. If any of the old grease has thickened/hardened, it will restrict grease coming out the zerk hole. I generally limit to 4 strokes on hand grease gun or start of grease coming out removed zerk hole. Also, use precisely whatever grease the label on the prop calls for, whether that is Aeroshell 6, 22 or some other flavor. Unlike oils, greases do use different thickening agents, and they are not all compatible. Do not worry about not having enough grease...there is plenty in the hub, unless you see it slinging out the seals at the blade roots.

You don't know that you haven't delivered an excess. You do NOT need the cavity full. The prop really only needs 1-2 pumps of grease per blade. The extra pumps are for those that may have substandard grease gun, to give you a safe range without excess. Excess will cause grease to get past the blade seals and may cause them to fail. Based on both Hartzell rep and pubs, and prop overhaul shop.

I think that's the question I was getting at. Until it oozes out the othe r side, you really have no idea the true quantity of grease in the hub.

One important tip is to make sure you clean out the exit hole per Hartzell=99s instructions, piece of safety wire works well. I didn=99t do this at first but after pumping some grease in I cleaned it out better and once the dried bit got out of the way some came out under pressure. As long as you limit the number of pumps it=99s probably not a huge deal, but if you are looking to see some exit then it=99s critical otherwise you=99ll pump too much in and it will find a way out in places you don=99t want it to.

I with Linn- unless I can see grease, I would have no idea how much grease is actually in the hub. I get it, after this thread, that 6 pumps may be enough grease for the what Hartzell requires, but I prefer to know there is grease coming out and that I am not short on grease (aka- I thought I pumped it 6 times but the amount of grease that came out was minimal for those pumps) to answer your question Rob- every annual. What I find interesting is that although I fill the hub, every year I seem to need 6 or more pumps to get the grease to show, which tells me I use more grease each year than I re-pump, hence my going until I see grease come out and sometimes, as mentioned before, when its really dirty, until I see cleaner grease. 3 years with no leaks, so I am happy knowing I have grease in the hub and that it cleaner each year, than just 6 pumps.

The manual for greasing the hub does not make a whole lot of sense IMHO. If the hub is not leaking grease, as it should not do, it will eventually fill with grease and after a few times servicing the hub will fill up and ooze out the the removed zerk fitting hole.

I don't know, I think some of the doubters should test the theory and just pump it full until it comes out...

I had some grease or something on my windshield last year after my annual and going to Oshkosh. Stopped at the hartzell booth to ask them their thoughts. They were very Responsive and concerned. I was then introduced to Scott Foster. Talked to him he got my contact info And called me the week after Oshkosh. They wanted to inspect my prop. Scott came up the next week and we removed the spinner Looked for leaks and determined a zerk fitting was a little loose. And leaking. Tighten it up Then we discussed the amount of grease. I had told him I pumped until Some came out. He said that 2-3 pumps no more. I pumped way more than that. The good news my prop was ok and he Said everything looked great for almost 500 hrs. But he did say no more than 2 pumps and told me not to grease mine at the next annual. Great customer service and Scott is great. Then I took him for a ride in the RV-10. He was impressed with the performance and loved the RV-10. He was drinking the the RV-10 koolaid and loving it.

So that leads to the question, why does their manual state six pumps? If that's too much and they are recommending something different, shouldn't Hartzell update the procedure in the manual? Then we have the issue of does my gun pump the same volume as somebody else's? It seems like it's still using a bit of magic and luck, since there is no effective method to measure the actual volume of grease until you pump too much and it oozes out the back.

It's a real WAG on my part, but I'm guessing that the volume of grease isn't anywhere near critical. The WAG part: if there's sufficient grease to coat the blade seal to keep it flexible and offer some lubrication to the hub ... it's sufficient.

I don't get it. There is an insurance company that baffles my mind. They specialize in direct sales (which you would think would be efficient), and advertise heavily to the experimental community in direct mail, magazine ads, a huge presence at OSH, etc. I get mailers all the time from this company and twice I have allowed them to offer me a quote, and both times that have been nearly twice as much as what I eventually ended up with. This last time I asked the embarrassed rep of this company why their quotes are so out of line and the answer I received was that the company truly isn't interested in making competitive quotes to experimental aircraft. So why, I asked, do they spend so much in marketing to a market segment they don't want? "I don't know" was the answer. "We deal with this every day." I told them they could reduce their mailing costs by removing me from their list and that they should probably reconsider their expensive ads claiming to love experimental business. Obviously they must underwrite enough paper to stay in business, but it sure seems like a strange way to operate to me. -------- Myron Nelson Mesa, AZ Flew May 10 2014 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=440391#440391 ________________________________________________________________________________

What a coincidence! Although I didn't bother last year, just last month I asked AVEMCO for a quote. Just to see if anything had changed. The answer is no change. Coverage limits are still "per person", not "per passenger" like everyone else. And, almost twice as expensive as my current policy (up for renewal soon). BUT, when I asked for a quote 2 years ago, they did send me a nice baseball cap with their name on it. My hangar-neighbor remarked that that was the most expensive cap he had ever seen.

BTW: Two years ago I asked Jenny (Nationair) why they didn't quote company X, which some others were reporting as offering very attractive rates.

I have the Bogart (sp?) tow bar, with the slight mod of two tabs attached to the ends to go over the rudder bars, under the brakes. Not sure if that works with your pedals. Handle goes against the seat back, held down by seat belt. stick goes thru the triangular hole. Not sure if your cover will fit, but the hole is pretty big. Use the other seat belt to hold the stick firmly in the 'V'. Hunt around the forum, I'm sure there are pictures somewhere. Works great, cost nothing, adds no extra weight, since I carry the tow bar anyway. -------- Bob Turner RV-10 QB Read this topic online here: http://forums.matronics.com/viewtopic.php?p=440410#440410 ________________________________________________________________________________

Subject: Lord adhesive window installation question
From: Dan Charrois <dan(at)syz.com>
Date: Apr 07, 2015
Hi everyone. I'm ready to attach the windows in my RV-10 and am looking for advice on those who have used the Lord 7545 A/E adhesive sold by Geoff at Aerosport Products. After reading lots of positive comments from here about it, I obtained a few tubes from him. The plans call for installing the windows onto the doors when the doors are off and laying flat, presumably to allow gravity to help hold them in place while they are being cured. Of course, the rear windows can't be installed with that luxury, but they're smaller and lighter. And the windscreen rests largely on the nose while curing, so that should be less of an issue too. But my question is, considering that Lord Adhesive is different than Vans' would have us use anyway, is it sticky enough that I could install the windows on the doors while the doors are closed and on the plane - in essentially the same orientation as the rear windows? The reason I ask isn't due to laziness :-) But instead, I'm one of the lucky ones whose doors ended up fitting quite well without a lot of work. And I figure that if the windows are attached to the doors while the doors are in their proper latched position, they can only help (slightly) to further stiffen the door in the proper position. The last thing I want to do is to fit the windows to the doors when the doors are on the floor, and then find that gravity warped things slightly while they were curing, and the doors no longer fit properly. It would seem to me that adhering the windows to the doors when the doors are in their closed position will help keep everything aligned properly, so long as the Lord adhesive is sticky enough before fully cured that it will hold the window tightly to the door and in place while it is curing.

The short answer is no. You need minimal pressure to hold the windows in p lace. If gravity causes any movement at all, you're going to have a major h eadache on your hands to resolve.

I made an H type out of PVC and and extending pole used for paint rollers so I can easily adjust the length. Just cut it to size and rivet PVC parts in place. The handle of the pole end is rubber (no slip) so it just presses against the seat base just above where the stick comes out. Then position it on the top of the pedals so it also functions as a parking brake. The PVC pipe ends of the H fit perfectly into holes in pedals. Velcro strap secures it to the stick. Works very well. Very easy to make for minimal $ and very light weight. Pretty much impossible to NOT remember to remove before flight.

I did not use the Lord adhesive as I copied Dave Saylor's method using Silpruf instead. Silpruf almost has a proseal consistency so it might be less viscous which lends itself to this process a bit better maybe? I glued the door windows in while attached to the plane. I used several tie down straps and blocking to apply even, light pressure to the windows as well as duct tape to keep them from moving. I did this for both the door window transparencies and the fuselage ones. I think they came out ok but the only air time my project has seen is dust falling on it in the garage so YMMV. See pictures.

Since my RV-10 seems to be the poster child for bad decisions made with respect to window adhesives, I'll update the story. I used a composite adhesive back in 2007 (no longer on the market) that Glasair builders were asserting was much better than Weld-on 10. In 2011 at about 450 flight hours, I had a rear window blow out in high, cold conditions (15K feet, -12 C outside, inside heaters blasting). It was a big surprise and caused a lot of noise in the back seat and some turbulent air in the cockpit: http://faculty.washington.edu/dmasys/RV10/RV10_lostwind_rearview.jpg I replaced the rear window using Weld-on 10 as recommended by Vans. Fast forward to 2014, with 750 flight hours. Climbing through 12K feet to get over buildups near Eugene, OR, the entire pilot side door window shattered and departed the plane. Most of the window fragments hit the VS and HS, making a variety of dents in the leading edges. But some of them came in the cockpit at high velocity. Luckily I had the Rosen visor swung to the left, providing an extra layer of protection. A window fragment shattered the Rosen visor; I got a small neck lump from the impact, but nothing drew blood. So we continued on and made it back to base. (Performance observation: an RV-10 that does 170kts with all of its windows intact will still do 150kts at same power setting with the pilot side door window absent, but it is awfully windy inside). Suffice it to say, I removed and reattached the remaining windows with Weld-on 10. Moral of the story: make sure you have a compelling justification for deviating from Van's directions on mounting the RV-10 windows. -Dan Masys N104LD Subject: RV10-List: Lord adhesive window installation question From: Dan Charrois <dan(at)syz.com> Hi everyone.

I'm paying $2K (as of 10 months ago) for about the same coverage. Another factor they look at is your annual flying. Too much and your exposure is high; too little and you don't stay current. You want to be somewhere in the middle but I have no idea what the actual number desired is. Tim is right, expect higher rates until you have 100 hours in type. And some minimum total.

This is why it's hard to compare policies. Hull, liability limits, deductibles etc. can change a little and make significant changes in cost. The best you can do is contact their broker and get a quote with your numbers. Your broker will poll the available insurance companies still doing aircraft insurance. There are other factors ..... how long have you been with this company and do you have more than one aircraft insured. The little things create a minefield that make comparisons really difficult.

When I attempted to use the one I had, I realized that these door locks are "clocked" 45 degrees off of what they would need to be for the cam to be level in the closed position. The included cam has an 8 point mounting hole that allows it to be clocked to the desired position, but the one I have is square. I called the manufacturer and they do not make a longer cam.

Thanks to the posters on the rates that you pay for comparison shopping of insurance. I had my quote move down to $2027 for $1mil/100k/150,000 hull. I have only 25 hours in a RV10, but have had my RV8 with them for several years and I have 16,000 hours TT, so I will expect to see the price drop at renewal with more time in type. I think that this thread is useful for people to get a feel for what they should be seeing for the quotes that they are getting, even though there are many variables to consider. With just a few responses on this forum, I feel more secure that I=99m paying a rate that isn=99t grossly out of range. I was able to have my agent =9Cfine tune=9D the original $2400 quote down to $2000 after getting these responses. It turns out they =9Cforgot=9D to include the large discount for being hangared.

Because the cutout is square in the Vans supplied cam, It will not rotate properly. When the lock is installed in the door, it is off by 45 degrees. The only way I can see making it work is to modify the square opening to an 8 point opening. Attached is a crude drawing of what is happening.

That looks like my only course of action right now. It gave me pause that I am the first person that ran into this. That usually means I am looking at it wrong!

I agree with William. Vans included a longer cam that replaces the one that comes with the lock. I ended up making one so that I could embed a disk magnet in it and then installed a reed switch in the door jamb. That switch is hooked in series with the passenger door switches. All 5 switches are hooked in series, 2 per passenger and one on the luggage door. Therefore, if any door is not latched, I get an indicator on my panel telling me, just not which one. i bought both the magnet and switch from Amazon.

Or you can use shorter grips. I got them from a guy in New Zealand, and they clear the panel just fine without any bending of the stick. They look a bit similar to the Infinity grips, just less buttons. They are ambidextrous. http://www.compositesinternational.co.nz/gallery/ You are probably far down the path to bending the stick :) but just for future reference...

Subject: NTSB - Probable Cause
From: Phillip Perry <philperry9(at)gmail.com>
Some of you might have seen this already, but Doug Nebert's probable cause was published today. This was the accident in Oregon last May. (2 Fatal - 1 Serious) - The probable cause document <http://www.ntsb.gov/_layouts/ntsb.aviation/GeneratePDF.aspx?id=WPR14FA218&rpt=fi> is a humbling read... - Every document in the entire docket <http://dms.ntsb.gov/pubdms/search/hitlist.cfm?docketID=57129&CFID=524058&CFTOKEN=34830451> is worth the read... - Specifically the photos in this document <http://dms.ntsb.gov/public%2F57000-57499%2F57129%2F570028.pdf> are full of emotion. Anger, Sadness, Disbelief, Confusion. In case the links do not work, the case ID is WPR14FA218 so you can look it up yourself. I will give you the nutshell, but you need to go read the documents. RTV was used to seal NPT fittings on a (recently installed) fuel flow transducer. A ~0.25" chuckof RTV came loose and flowed downstream into the metered nozzle of the transducer. The metered hole was ~0.115" in diameter and the RTV plugged the hole and starved the engine of fuel. To make matters worse, a stall (and likely the start of a spin) occurred during the forced landing. This is worth a read. There were other indications of an aircraft with questionable maintenance, but the event that brought down this airplane was 100% preventable. The real disappointing part is that the issue was pointed out by a friend but ignored. Even if we don't have RTV on our fuel lines (I hope we don't - Same thing for Teflon Tape), there is a lesson in here for all of us. It doesn't do us any good to share information and concerns with each other if we aren't going to take a moment to stop in our tracks and seriously listen to them. Ears open, mouth closed, stop, and think. I'm as guilty as the next person, but this is a case where we can all reset ourselves and improve our fleets record.

Subject: Re: NTSB - Probable Cause
This whole story really saddens me. In the 34 years I've been around experimentals I've seen a lot of 'stupid builder tricks' done by intelligent, knowledgeable builders. I rank them up with running out of fuel and VFR pilots flying into IFR conditions. How does it happen? What thought process took them down the path to the ultimate failure??? I've seen experimentals I wouldn't even sit in, much less fly in. Glaring construction practices ..... not hidden like this case ..... where a lot of 'counseling' was ignored, resulting in a fatal accident. Many were personal friends. In this case the builder was informed of a prior, improper use of RTV, but it didn't matter. It's sad, but our hobby is shot through with 'experts' that also think 'their way is a better way', and the newbie builder is cannon fodder for their misguided information. I'm guilty of failing to 'just build it' ..... I don't like the way some things are done ..... but the mods are done with all the information found in AC 43-13. I really feel that no builder should be given an airworthiness certificate unless he/she produces their own copy. It would have saved a fair amount of lives. Over the years I've tried to learn what went wrong in an accident scenario, not just the cause, but where/how the failure came to be. This one was obvious, many others are sinister and lie it wait for years. Phil is spot on .... we are our brothers keeper ...... As a point of perspective, we read/hear/know of an accident where a highly skilled (famous, prolific builder, pilot, etc.) is no longer with us because of an aviation accident ..... if they go west prematurely, what chance do I have to grow old and die of natural causes??? All I can do is try to learn from their demise and become more knowledgeable, and hopefully make the proper decisions down the road. If you deviate from the norm (it's that mod thingy again) please get as many opinions and sets of eyes as you can, just in case there's a flaw in your thought process. What you learn may not be entirely correct, but the discussion adds immeasurably to your analysis. I now relinquish the soapbox.

I have the Aerosport Panel and did not have to bend the stick. What I did was to cut the lower end as short as possible to leave enough straight left to slide into and fully engage into the lower attachment joint. I trimmed the top as short as possible so the holding when the grip my arm would be able to relax on my leg. -------- Bill WA0SYV Aviation Partners, LLC Read this topic online here: http://forums.matronics.com/viewtopic.php?p=440562#440562 Attachments: http://forums.matronics.com//files/stick_2596_286.jpg ________________________________________________________________________________

Subject: Re: NTSB - Probable Cause
Phil, Thanks for posting. That's just sickening to read. Regarding Linn's post, I truly think that the people who most often do the very questionable things are also the ones that will never listen to the advice, so it's a hopeless plea, sadly. I think back to how many times I had to get on Dan Lloyd and he never listened once. This particular accident/pilot was far less lax than Dan was, but still, there are just far too many things in the report to allow me to just think "well, at least he knew what he was doing". It was a shocking read, and horrifying when you consider the discussion about the crash and the child, and see the numerous pictures of the plane. There isn't anything left of the front end, and you can't blame the angle of impact on anything but poor piloting, even if you excuse the RTV use. This accident didn't have to end this way. Some things I noted... The fuel handle was installed reverse indicating. Why? Why can't a pilot understand that things like that are critical, and you need to install them so that ANYONE can understand them? Of course, the RTV on the NPT threads... So how many times do we have to discuss this? No teflon tape, no RTV. Fuel lube I guess is the common one, which is good. If you use a paste of any type, or even in the case of anti-seize on spark plugs, you don't put it on the first couple threads. These are just common knowledge practices. You don't want to contaminate the inside, nor give opportunity for the compound to come off inside. Here's one I'm not familiar with. The electric fuel pump was a "Facet Automotive". Someone else help me out here as I'm not familiar with the carbureted RV-10 fuel system. Is that a normal pump, or something hacked in? I know Facet pumps are used often, but is that the proper pump? Fuel systems aren't something to screw with, so hopefully that was the right one. The fuel selector position, and key position it's hard to interpret. Not good for trying a restart, but the fuel valve off for the crash is a good thing. Not sure what to think about the key position though. There seem to be numerous issues with the plane. I hate it when I hear of people flying continually and regularly without addressing an issue. I mean, he was frustrated with the "constant hassle" of having to reset the alternator in flight. REALLY!?!? I think if mine blows ONCE I need to look at it. Twice and it's an issue for sure. But constantly in flight? WTF are you doing carrying passengers if this is the case?!?! That blows my mind. Then there's the 125psi fuel pressure. Again, you have an indication like that and you just fly it?!?!?! I met a guy once who never calibrated his engine sensors. You have to add proper scale factors and offsets for them to even read accurately. He adjusted his oil pressure on the engine to match his NON-setup instrument. Then found out how to set the instrument up from me. WTF is that about!?! You didn't have time to do that before you first flew? Far better than killing yourself! My only comment to people like that is "THINK!!!!" Then there's the comments from people that they tried to start the engine and the "stater wasn't connected" which it sounds like is actually that the starter was falling off the engine and not making contact. He had heard it making noise on previous flights and now it wouldn't start. Again, REALLY? You hear something odd and don't investigate it? Another one... the Prop only made 2450 RPM, but that's the way it's always been so it wasn't fixed. REALLY!?!?!? So something as important as your engine making the power it needs to isn't important to you? Truly I say, here is someone who just didn't give a crap about doing things "right". There are too many indicators. Didn't put the fuel transducer in earlier because it needed a certain amount of space and had to bend tubing to do it. Gosh, so that's a reason to just not install it then? Then finally DID put it in, but used RTV and didn't connect any wiring to it. This should have been done PRIOR to the first flight. And I don't care if you're Sean Tucker, if you're flying a carbureted airplane you shouldn't consider yourself "not a big proponent of carb heat" if you're going to fly IFR (or even VFR). Carb heat provides a very specific function. If you want to ignore it on your landing prep, that's one thing, but if you dang well better know when is a good time to think about using it. And finally, a plea from me, to you. If you're not someone who's going to thoughtfully approach your build, and try to do things right, please try to refrain from using my name in your internet postings. I know, I know, his Andair fuel valve install wasn't involved in the crash cause at all, other than maybe the fact that he put the handle on reversed, but I wasn't thrilled about seeing that he referred to me in his forum post. If you like what you see, copy it, but if you're doing all sorts of other stupid things, just leave my name out of it. It's like not calling it a "Van's RV-10" if you're going to significantly modify the airframe. I don't need to be tied to your improper methods of build or maintenance. Better yet, just try to do everything to certified aircraft standards and procedures and you won't have to worry about what your NTSB report reads like (or at least cut your chance). Sorry, that may have been part analysis, part rant, but it drives me nuts to see some of the things that bring down planes, especially RV-10's. So far there's been only a very tiny fraction of accidents that were not directly attributable to something stupid that someone did. Let's try to eliminate those sorts of things because we'd have a *near* spotless safety record on our make and model if you eliminated the things that were pure ignorance and idiocy.

Tim, This needed to be said and you did it well. We all need to be reminded periodically that this is serious business. We should be taking pride in learning how to build and fly our planes to the best of our ability rather than looking for shortcuts. I remember well trying to find a way to console Dan's wife at his funeral. Not fun. Dick Sipp ________________________________________________________________________________

Subject: Re: NTSB - Probable Cause

Tim; Your rant is merited. As you know I and I'm sure many others respect you and your integrity with building. Dan served as a sad but great motivator to me to assure I NEVER fly anyone in my plane until I know it is perfectly (or as perfect as I can expect). Your feedback on that accident served as large part of my CAP presentation many years ago. When I went through "youre the inspector" and showed the events many thought I made up the whole story up it was so far fetched that anyone would do this. I agree that 4 years later we find that another person followed the same road. when I was given my Airworthiness, but the same person who was my Technical Counselor, who insisted in seeing the various phases of my build before signing off the final pink slip, he would not allow me to pass without showing him the panel and the steps I took to assure it met the "initial airspeed and gauge ranges". The fact was simple in his mind.. The first flight is when something may show up.. in my case way high oil pressure, that is no time to determine you have an issue. For someone to go so many hours without an issue is amazing in itself, but to be so nave to fly another person in such a poorly managed airplane is another Dan episode. I have been told, more than once, that what I am doing isnt necessary, but anyone who knows me knows that I take hours researching GAMI folks, EAA speakers and Lycoming and come up with my own theory on engine temps and if "its normal". point here is not one person but a few comments that I consider. I usually take the experienced folks I know, one being in a airpark in Texas and listen carefully for what, when needed I should change. This forum is full of ideas, most are excellent some overkill, but I still take your feedback very seriously Tim, and when you play such a huge part in a forum, writing articles for magazines and being a -10 (soon to be -14) guru, your name will come up. There is that 1% of builders who will make the rest of us look bad, but from what I have seen and the folks I have met, there is 99% solid folks who really are concerned about doing a proper annual and certifying they actually did everything. I am constantly looking at other demises, some are just bad luck and planning, some plain "Darwin award candidates" but some are something I have found myself being in at one point, the decision of a NTSB report was recalled and I made a decision based on "lessons learned", in that case in Texas, we landed, all it was was a rain shower (with huge clouds exploding up) but I was tempted to go on, Im here and the decision may have been overkill, but at least can see that the plane is safely sitting in the hangar for the next flight today. Yes, this event is a sad one, hopefully none of us will learn anything, other than dont cut corners and use the wrong product for the job, but it may be a reminder for something we have done that may cause us to consider changing how we did it. (use a torque wrench on a fitting versus it "being tight enough", etc) Our first day of Officer basic in Fort Rucker we had an officer walk across the grass, versus walking on the walkway. The Commander at the time told us all that "if we cut corners on something as simple as following the walkway, we would find ourselves cutting corners in the way we lived our lives and in the aircraft" Be safe and enjoy the flight! Pascal -----Original Message----- From: Tim Olson Sent: Friday, April 10, 2015 8:19 AM Subject: Re: RV10-List: NTSB - Probable Cause Phil, Thanks for posting. That's just sickening to read. Regarding Linn's post, I truly think that the people who most often do the very questionable things are also the ones that will never listen to the advice, so it's a hopeless plea, sadly. I think back to how many times I had to get on Dan Lloyd and he never listened once. This particular accident/pilot was far less lax than Dan was, but still, there are just far too many things in the report to allow me to just think "well, at least he knew what he was doing". It was a shocking read, and horrifying when you consider the discussion about the crash and the child, and see the numerous pictures of the plane. There isn't anything left of the front end, and you can't blame the angle of impact on anything but poor piloting, even if you excuse the RTV use. This accident didn't have to end this way. Some things I noted... The fuel handle was installed reverse indicating. Why? Why can't a pilot understand that things like that are critical, and you need to install them so that ANYONE can understand them? Of course, the RTV on the NPT threads... So how many times do we have to discuss this? No teflon tape, no RTV. Fuel lube I guess is the common one, which is good. If you use a paste of any type, or even in the case of anti-seize on spark plugs, you don't put it on the first couple threads. These are just common knowledge practices. You don't want to contaminate the inside, nor give opportunity for the compound to come off inside. Here's one I'm not familiar with. The electric fuel pump was a "Facet Automotive". Someone else help me out here as I'm not familiar with the carbureted RV-10 fuel system. Is that a normal pump, or something hacked in? I know Facet pumps are used often, but is that the proper pump? Fuel systems aren't something to screw with, so hopefully that was the right one. The fuel selector position, and key position it's hard to interpret. Not good for trying a restart, but the fuel valve off for the crash is a good thing. Not sure what to think about the key position though. There seem to be numerous issues with the plane. I hate it when I hear of people flying continually and regularly without addressing an issue. I mean, he was frustrated with the "constant hassle" of having to reset the alternator in flight. REALLY!?!? I think if mine blows ONCE I need to look at it. Twice and it's an issue for sure. But constantly in flight? WTF are you doing carrying passengers if this is the case?!?! That blows my mind. Then there's the 125psi fuel pressure. Again, you have an indication like that and you just fly it?!?!?! I met a guy once who never calibrated his engine sensors. You have to add proper scale factors and offsets for them to even read accurately. He adjusted his oil pressure on the engine to match his NON-setup instrument. Then found out how to set the instrument up from me. WTF is that about!?! You didn't have time to do that before you first flew? Far better than killing yourself! My only comment to people like that is "THINK!!!!" Then there's the comments from people that they tried to start the engine and the "stater wasn't connected" which it sounds like is actually that the starter was falling off the engine and not making contact. He had heard it making noise on previous flights and now it wouldn't start. Again, REALLY? You hear something odd and don't investigate it? Another one... the Prop only made 2450 RPM, but that's the way it's always been so it wasn't fixed. REALLY!?!?!? So something as important as your engine making the power it needs to isn't important to you? Truly I say, here is someone who just didn't give a crap about doing things "right". There are too many indicators. Didn't put the fuel transducer in earlier because it needed a certain amount of space and had to bend tubing to do it. Gosh, so that's a reason to just not install it then? Then finally DID put it in, but used RTV and didn't connect any wiring to it. This should have been done PRIOR to the first flight. And I don't care if you're Sean Tucker, if you're flying a carbureted airplane you shouldn't consider yourself "not a big proponent of carb heat" if you're going to fly IFR (or even VFR). Carb heat provides a very specific function. If you want to ignore it on your landing prep, that's one thing, but if you dang well better know when is a good time to think about using it. And finally, a plea from me, to you. If you're not someone who's going to thoughtfully approach your build, and try to do things right, please try to refrain from using my name in your internet postings. I know, I know, his Andair fuel valve install wasn't involved in the crash cause at all, other than maybe the fact that he put the handle on reversed, but I wasn't thrilled about seeing that he referred to me in his forum post. If you like what you see, copy it, but if you're doing all sorts of other stupid things, just leave my name out of it. It's like not calling it a "Van's RV-10" if you're going to significantly modify the airframe. I don't need to be tied to your improper methods of build or maintenance. Better yet, just try to do everything to certified aircraft standards and procedures and you won't have to worry about what your NTSB report reads like (or at least cut your chance). Sorry, that may have been part analysis, part rant, but it drives me nuts to see some of the things that bring down planes, especially RV-10's. So far there's been only a very tiny fraction of accidents that were not directly attributable to something stupid that someone did. Let's try to eliminate those sorts of things because we'd have a *near* spotless safety record on our make and model if you eliminated the things that were pure ignorance and idiocy.

I think it's somewhat of an ego thing to a certain degree. It's hard on our egos when somebody calls out something we have done wrong on our "babies"!

Subject: Re: NTSB - Probable Cause
Yeah, that crash was the first, and it had a big impact on a lot of us. I guess if you're going to have a crash at a particular time, that had so many warning signs, that may have been as "good" a time as any. It got a lot of people to stop and reflect on what they have in their garage, before they went out to fly. I also hate to be so "down" on this pilot in this crash that we're talking about today too...it's not my intention to just criticize the pilot, but it does put the blame where it lies, and as usual, he didn't just take his own life with him. So it serves as a good attitude check for us all. It's sad that we even need that sometimes. Overall, I think it's easy to see that the RV-10 has proven to basically have an unscathed safety record when it comes to the airframe. In thinking through the fatal and non-fatal crashes we have on the list, pretty much every one of them was caused by someone doing something they shouldn't have. This should be comforting to us all in that it does show that the onus is on US for the ability to safely take our passengers from ground to sky to ground again without incident. I not only do not want to dodge responsibility for my flights, but I want to accept it happily. I am personally glad that the NTSB does not pull punches and lays the blame on the pilot almost every single time. It really is up to US to make sure that we aren't the next statistic. NOTHING that we are doing is ground breaking and new. There have been hundreds and thousands of people who went before us and paid in blood for all of the rules and regulations and designs that keep us safe today. If we fly our best and use our best judgement, we really should not have need to worry much about the successful outcome of any flight. (with few rare exceptions) Certainly we enjoy a far better safety record than many other models of airplanes, and that we should be humbly proud of.

"We have met the enemy, and he is us" - Pogo The other sad thing about both Dan and Doug is that, when faced with the ultimate high-stress test, they both failed as pilots. And they're not alone. No matter how often it's drilled that you never let the plane stall, that you fly it into the trees or until it won't fly anymore, both allowed it to stall while still a fatal distance above the ground. I suspect that we all think we have 'the right stuff', that we wouldn't do that. Yet some of us do. Clearly biennially doing a few stalls at 4000' isn't good enough. And stall training very low is too risky. Is there any way to do realistic training outside of a million dollar simulator? How can we get the "save the plane" mentality out of our thinking? Do we do too much "simulated emergency" training where there's always an airport right below us? What's the right training mix of benefit vs risk? I sure wish I knew the answers to these questions. -------- Bob Turner RV-10 QB Read this topic online here: http://forums.matronics.com/viewtopic.php?p=440599#440599 ________________________________________________________________________________

Do we do too much "simulated emergency" training where there's always an airport right below us? What's the right training mix of benefit vs risk? I sure wish I knew the answers to these questions. I've had three off-field emergency landings and one on-airport emergency landing, and with the help of all those angels on my shoulders, they were non-events .... no further damage to the airframe, pilot, people/property on the ground .... or the ground. ;-) I firmly believe that we really have no clue how we will react when the s..t hits the fan ..... until it does. All we can do to prepare for emergencies is to think .... 'how would I handle that ?????' when we read of an accident or incident. I do that all the time. I learn from survivors how they handled their 'oh s..t' moments. The problem with emergency training is that there are far too many ways for disaster to occur than we have the time/knowledge to prepare for them. We just try and cope the best we can. Sometimes we win, and sometimes we lose. I think it was Bob Hoover who said 'Fly the airplane as far into the crash as you can.' Sage advice. Trying to stretch the approach to the impact point with insufficient energy will most likely turn a flying airplane into a lawn dart. It is, as you said, the 'save the plane' mentality, and I've lost friends because of it. My airplanes owe me nothing .... I've had so much pleasure with their use that if I lose one .... I hope to be around another day to fly again. Yes, it will be painful, and I'd be happy to survive and mourn.

Subject: Shoulder Harnesses
From: Phillip Perry <philperry9(at)gmail.com>
Last night I was thinking about the images in Doug's photos and was really curious to know how effective the shoulder harness anchor bolt is in that situation. My curiosity stems from seeing a friends Culver Cadet (no shoulder harnesses in that old plane) that he landed off field 7 years ago. It's still sitting in his garage and has a pair of human head shaped indentations in the glare shield. If he had effective shoulder harnesses, it would have saved them some blood and a deviated septum. We've had a handful of RV-10 accidents that have tested the integrity of the shoulder harness anchor bolt possibly being pulled through the fiberglass hole. I just wonder how it really performed in each of these accidents. 1) Have any of you seen, first hand, an RV-10 airframe after it has been in an accident where the shoulder harnesses were stressed significantly? 2) Would any of you know where we could get that information? Perhaps a FOIA or something similar? I'd really like to get the real details on how that shoulder harness performed. We've probably got 5-6 accidents where that information could/would be collected.

Phil, I think it's worth considering that if the harness bolt is pulled in the intended direction, it seems to me that it would be loaded in shear, not tension. So if the crash is survivable, the bolt pulling through the cabin cover isn't what we would see. I'm not an engineer, but I did copy the front mounts for my rear inertia mounts...and I wondered the same thing until it occurred to me that the bolt gets tugged in a line approaching the direction of flight. I don't think it would get pulled through. --Dave On Fri, Apr 10, 2015 at 3:29 PM, Phillip Perry wrote: > Last night I was thinking about the images in Doug's photos and was really > curious to know how effective the shoulder harness anchor bolt is in that > situation. > > My curiosity stems from seeing a friends Culver Cadet (no shoulder > harnesses in that old plane) that he landed off field 7 years ago.

Well, I'd say the front harness mounts see a substantial amount of tension as well as shear. Looking at the photos and the text, it appears a large section of the left roof failed. I wonder if the forces exerted by the shoulder harness contributed to this? Or did the roof fail only after experiencing an unsurvivable loading, say more than ten times the pilot's weight, from the harness? Or was the failure due to crash forces applied directly, independent of the harness? -------- Bob Turner RV-10 QB Read this topic online here: http://forums.matronics.com/viewtopic.php?p=440623#440623 ________________________________________________________________________________

Phil, Good questions. Lacking data however I evaluated the canopy top fiberglass t hickness for the pilot and copilot shoulder harness anchor points less than a dequate considering the significant countersink depth needed to have the anc hor screw flush with the cabin top. Again, no data to say my evaluation was correct or not. I added several bids of glass on the inside of the canopy top for each ancho r point. The first layer being 1/16" thick covering an area of 10" by 10" o r so, then another 6" by 6", 1/16" or so layer on top of that. The objecti ve being to allow for fairing with the rest of the bottom of the cabin top. This resulted in sufficient thickness for countersinking the head of the an chor screw such that it was slightly below the surface of the canopy top. I flatten the screw edges and installed the anchor screw in some flox as I wa nted to make sure it would not turn when tightening the nut onto the inside. Sanded the flox flush, a layer of glass on top of that, then a skim coat o f micro balloons to fair it in.

What about that crash near Lake Placid Airport in NY that went into the trees in the cold. All occupants walked away OK with minor injories. There was also the one in SoCal, Ramona RMN that put it on a hillside into terrain and walked away. Seems the belts and airframe performed as designed on those instances. I think the key is survivable impact. I=99d hazard a pretty safe guess that Van=99s engineered the structure appropriately.

I must be doing something wrong; every contingency I plan for never happens.

Fortunately, to date, every contingency for which I plan never happens.

I am not sure what problem needs solving here. Don't we think Van designed things correctly? There doesn't seem to be any evidence of a design problem. SWAG engineering just doesn't cut it here.

The question isn't why are they insufficient. They question is where do we go to find out how they have performed in the incidents to date. We have a decent set of incident data for off field landings. We have good half dozen incidents resulting in fatalities. None of the shoulder harness data is published but it has to be collected. It exist. Being able to review that data relative to the accident type/severity would let us know if we do have a problem or not. Dead men can't speak but the data would and we would all benefit by the factual data.

I do not think the question has been answered whether they are adequate, i.e. what force are they designed for in shear and in tension. I've not seen any evidence that they are inadequate. I believe there is a significant difference between the green and pink canopys, espec reinforcement behind the doors. The pink looks like it just about has a roll bar installed there, just in front of the shoulder harness bolt holes.

>From the Lake Placid NY crash... Preamble: It has been just over 2 years since this crash. On several occasions I have started to do a write-up on the incident. Each time I have tried I get tangled up in my own brutal self judgment. I am know as a very competent and conscientious pilot. 2,000 hours flying since 1986, instrument rated since 1989. At the time of the accident I was very IFR current, in a very capable aircraft, yet I allowed myself to follow a series of small events into a classic accident scenario. While I have flown over 100 hours since the crash, I still have a difficult time reconciling this in my mind. I remain confident in my pilot skills, but have an excessively conservative approach to the passion of flying. I will try to post a thorough synopsis of the accident in a separate post in the next few days. Please hold off on questions and comments about the crash until I post this as a separate thread. As for the airframe, the majority of the impact was absorbed by a side load impact. That impact contacted the fuselage on the pilot side at the junction of the leading edge wing root and the fuse at the instrument panel station. The entire panel and front of the fuse were displaced about 1 foot to the right. The lower portion of the fuselage separated from the fiberglass upper structure in that area. The remainder of the fiberglass top remained intact. The shoulder harness attach points showed no sign of stress or compromise. There was no impact bruising from the harness on any of the occupants. Due to the initial side impact, and subsequent wing leading edge impact with multiple pine trees as we descended the final 100 feet, there was minimal frontal impact when we came to rest nose down on the mountain. The RV-10 withstood a tremendous amount of impact damage, and the cabin remained a safe haven. I am almost done building a new RV-10 to replace N10FD.

Agreed. Very specific instructions from Hartzell - I just follow them.

After action report. I had access to a 55 ton hydraulic press. It took some effort to create fixtures to securely hold the stick so it wouldn't go flying out of the press. The stick as delivered from Van's had approx 10 3/4" diameter between inside surfaces. Packed stick with sand. Went slowly with first one. Discovered needed 3/4" of compression before getting any permanent bend. Compressed it to slightly under 9" measurement, which after release of pressure gave a 9 3/4" dimension. That was just right, as I could see the tubing just beginning to slightly deform. Second stick came out within 1/8" dimension of first. Now have full up and down travel on elevator without stick grip hitting panel, although knuckles might get a little bruising if really need full nose down.

Well I think I finally found the cause of this problem. The sl40 comes with 12" pig tail coax attached to the tray. It has a nut type connector that pinches the shield to the connector, and it was loose. I tighten the nut and it solved the problem. The actual amp draw indicated on the vpx-pro when transmitting ranged from 2.5 at the higher freqs, and 4.5 at the lower freqs, 123.x and below. The amp gauge on the EFIS only spiked when I transmitted on the lower freqs. If you are having this issue, check the coax at the back of the tray.

Subject: Fuel Return Line Location?
We're planning on EFII, so we need a full-sized return line for both sides. Just now starting work on the fuel tank, and I'd like to get this sorted before we get too far. I've spent awhile searching, and have only managed to find lots of places not to put the port for the fuel return line. Apparently it can interfere with both the wing spar and the aileron return line. Does anyone have a clear diagram of where I can safely put it? A hint about which flange/fittings to buy would be greatly appreciated as well. Thanks in advance! Berck ________________________________________________________________________________

Berck, I am using an EFII system as well. Just a thought, but I put a normal L/R/Both/Off fuel valve on the supply side (AN6) and an AN6 size return line that Splits to each tank. After the "T" I put a simple Parker petroleum 1/4 turn ball valve on each side just before the tank.

Hi Justin, You are of course free to build whatever fuel system you like, but the one you described has some issues. I think you'd be better off with a L-R-OFF duplex fuel valve that routes return fuel to the same tank you're burning from. You're headed towards a scenario that makes it pretty easy to mismanage the fuel: You could return to a full tank and waste fuel overboard; You could unport an empty tank in "BOTH" and starve the engine; You could turn off both return valves and...I don't know what, but it seems bad. Please consider a simpler system. Caution never goes as far as we think it will. --Dave On Sun, Apr 19, 2015 at 8:00 PM, Justin Jones wrote: > > Berck, > > I am using an EFII system as well.

I'm leaning toward a duplex valve, but I'm also considering two fuel valves, one for the source and one for the return. This isn't that different than jets I've flown, and I think I can handle the "complexity". It's cheaper and it gives the advantage of being able to transfer fuel, which might come in handy.

Dave, I understand your concern and welcome any ideas and thoughts that may be cause for issues. The issues you brought up have been considered and here is what I have come up with. Note that I have spoken with many others about this as well, but it doesn=99t mean that we aren=99 t missing something. The normal configuration (covered on the before take-off checklist) would be both return valves open and the fuel valve on both. The transfer of fuel during refueling operations (while the aircraft is on floats) is one reason for this setup, and the other is the ability to draw fuel from both tanks simultaneously. =9CYou could return to a full tank and waste fuel overboard=9D - This scenario could present itself, but would cause an over-pressure situation due to the vent size. The digital engine monitor senses fuel pressure and sounds an audio and visual alarm when it is either too high or too low. =9CYou could unport an empty tank into =9CBOTH=9D and starve the engine=9D - This scenario has also been tested. With one tank empty, one tank full, and the selector to =9CBOTH=9D, there was still full fuel pressure. This may be due to the high-wing design and the fuel system plumbing called for by Robert Paisley of EFII. =9CYou could turn off both return valves and I don=99 t know what, but it seems bad=9D - It would cause the fuel to back up at the valves, and the fuel pressure would increase to the maximum that the GL393 fuel pump would put out. This would be 105 PSI at 10 Gallons per hour. Not sustainable, but not harmful to the injectors or fuel lines for short periods of time. Again, the Engine Monitor will alarm when the fuel pressure begins to increase. The fuel system has been tested to the fuel pump stall pressure of 115 PSI and found to have no leaks. I fly C-130s and King Air 200s and they both have fuel systems that are far more complicated. Flying aircraft will always require thought. With the duplex fuel valve, the pilot must remember to switch the fuel valves when it is necessary. I like the idea of being able to operate in a normal scenario with the fuel valve on both, and have the fuel is return to both tanks. If the situation arises, I can put the fuel where it is needed and I have a good monitoring system that will alert me if I make a mistake in the positioning of fuel valves. The return valves do not have a position that will cause the engine to quit turning. Thoughts? Thanks for your input.

Bereck I had a similar setup to what your plans. Until a few months had a different engine (Subie) which I replaced with a IO540. I still use the return line for my purge valvle. I used an Andair duplex valve that returns fuel to the originating tank. With full tanks, you will pump a lot of gas overboard if the tanks / return line is mismatched. Running dual lines to the tanks is not a problem. I used an AN832 bulkhead union, mounted similar to that shown in the tank plans, to make the connection. I also a flange riveted to the inside of the tank to keep the union from turning when the nut is applied to the outside. Again see the tank plans. Lots of proseal made sure nothing leaked. You probably want to mount the fitting high and to the aft of the tank so that you do not interfere with the sender. If possible, you should run a tube from the fitting through the first tank baffle so that the returned fuel is dumped into the second tank cell. This allows it to cool and mix with other fuel before being reused. All of this is best done before the tanks are sealed. If the aren't, you can do everything (except perhaps for the fuel line to the second cell) through the fuel sender hole, it is just a bit tricky. This is what I did - I wasn't able to get the fuel back to the second cell but only to outboard side of the first. All my fuel lines in the tunnel were braided steel. Under the seats I had to go back to aluminum because of how the lines were run. My fuel filters are mounted in the wing roots - one for each tank. I completely agree with Dave's recommendation -keep it simple! You don't want to put yourself in a position where a simple error can lead to heartache and a bent air frame.

Berck, I added a 1/4" purge line return to the left tank when building in case I ended up with an AFP injection system (photo attached). This is the same location I used the RV-8A which had AFP injection. Adding a return line is straight forward and if you get the fitting in about the same area as the vent line connection you should not have an issue. I'd keep it high (like my photo) so that it is away from the fuel pick up - should help with pulling cooler fuel into the engine as compared to the hotter return fuel. Just curious - how much did this EFII system cost? Carl -----Original Message----- From: owner-rv10-list-server(at)matronics.com [mailto:owner-rv10-list-server(at)matronics.com] On Behalf Of Berck E.

Just keep in mind that what may be appropriate and work fine in a high wing aircraft is not suitable for a low wing aircraft. IMHO there is little to no need to transfer fuel between wings on a single engine aircraft. Managing fuel burn can easily keep the wings balanced, given that each wing only holds about 2.5 hours of fuel. The RV-10 wing arrangement is no place for a selector with a "both" position. It is too easy for someone scanning the archives of this list to get the wrong idea by a discussion of what works on a totally different airframe.

I think I'm flying Phase 1 in the first RV-10 with the full EFII system. I'm not sure how much fuel gets returned to the tank, but it is significant. We have a double stack Andair selector so it returns to the same tank that it is pulling from. I wouldn't have it any other way. It is so easy to do it this way that returning to one tank all the time, or having to process which tank you are pulling from and returning to would, IMHO, way over complicate things. As for the fuel return location, we put it forward in the bay and up fairly high. It's just a bulkhead fitting with a nut and ProSeal to seal it. If the tanks were open, we might have put in an NPT female bung instead, but this works just fine. There has been no problem at all with fuel vapor lock. I don't think it is necessary to return the fuel to the second bay. My fear if doing that would be the possibility of getting low on fuel and starting to suck air because you are dumping the fuel too far outboard. I don't know the exact effect, but it would expect that would effectively reduce your useable fuel level even more than it does by returning it to the first bay. Btw, the EFII system does add a lot of necessary complexity, dual bus, dual alternators, dual electric fuel pumps, dual ECU's, etc. It took a while to get up the nerve to be the test pilot on it. New airframe, new engine, new style ignition and injection system, etc. I will say, however, that it has been absolutely rock solid stable for all 10 hours so far. I need to put 15-20 more hours on it the week after Sun-N-Fun, but that shouldn't be a problem. In my mind, the jury is still out on the system, but they are starting to trickle in with a not-a-bad-system verdict.

Carl- thanks so much for the picture. I'll plan on the same location. As for the cost: We haven't purchased anything yet, and probably won't until we source an engine. Hoping available systems will only get cheaper, but cursory research indicates it'll cost not much more than more conventional FI and ignition setups. Jesse- Thanks for the heads up. Glad to hear that one is flying already, and I hope you'll keep us updated of any gotchas. After seeing that an EFII system is available, I can't imagine not using it. I'm aware of the need for a fully redundant electrical system and dual ECU's. I was already planning on dual electronic ignition and the dual alternators that necessitates, so electronic fuel injection only makes sense to me. This is, I think, the beauty of building an experimental-- the ability to use "modern" (30-year-old tried-and-tested) technology in an airplane, instead of being forced to rely on a fuel delivery system from the 1950's. Any RV-10 specific EFII links, information, vendor tips, etc, would be greatly appreciated. As for the "complexity" of a fuel return tank selection, it seems a bit silly to me that choosing a return tank is considered "overly complex." It's the difference of switching two valves instead of one when you switch tanks in normal operations. Sure, it's more complex than a single knob, but I'm used to much more complicated fuel systems many of which require deliberate knowledge of the fuel return tank. I'm not really concerned about it either way. The only reason to want to transfer fuel would be a leak, and in most situations, getting on the ground quickly makes a lot more sense than moving fuel around. Since I won't have to worry about the insane complexity of a mixture control, I can use those saved neurons to handle the fuel return tank if I wind up with two valves.

I think you're kidding yourself if you think there is no mixture to worry ab out. I spend more time on the mixture knob so far than I do on the mixture c ontrol with a standard system. It's possible that once you get things all tu ned up the way you want them you may not use it as much, but I really don't u se it that much on a standard system either. I lean a little as I climb, the n I set power, rpm and fuel flow for cruise. I would imagine if you are burnin 12gph, you are probably returning at least that much to the tank, if not more. I wouldn't want to have to mess with pi cking a return tank separate from a feed tank. There are warnings when your f uel in a tank gets low, but I don't know of a warning saying your tank is ge tting too full. If you get busy or get bored and aren't managing fuel with a normal system, you will get something yelling at you saying you're getting i nto the red on the draw tank, but it won't happen if you start to pump it ov erboard through the return tank vent. I agree that electric ignition is tried and true in cars, but so far there a re a total of 10 fleet hours in the RV-10 with a full EFII system and thousa nds and thousands with mags and standard fuel injection. Far from a no-brain ier in my book unless you are talking the other way around.

From: "Berck E. Nash" <flyboy(at)gmail.com>
Since the fuel is metered directly at the injectors by the ECU, why do you have to mess with the mixture knob? The EFII website says, "Automatic mixture control (no mixture knob to fool with)", but you're saying that's not entirely true? Is the issue that you're compensating for a lack of initial ECU programming by altering the fuel pressure until the you get the programming dialed in? Since the system has a MAP and IAT sensor, it seems like it should be able to meter correctly without any input from the pilot. It doesn't look like the EFII includes an oxygen sensor, though? Any idea if there are plans to fly this plane on automotive gasoline?

WRT auto fuel, while the injection system may be ok with it the rest of the system is problematic if you are unable to get ethanol free premium unleaded. If you can get this fuel the IO-540 D4A5 is already approved for its use. Years ago a =9CEFII like=9D company wanted to use my RV-8A as a beta for their single lever electronic fuel injection system. After a lot of research it became obvious that how I wanted to run the plane (LOP to my set point) was not possible =93 I would have only whatever the software wanted me to have for mixture. That and they wanted a boat load of cash for the system and my testing/fixing time for free killed any interest I had. Perhaps this EFII product has advanced from that of my experience. On the ignition side, I=99ll be bolting on the new 200 series P-mags in June (I hope). I have a lot of hours with P-mags on the RV-8A and they have performed flawlessly. Any ballpark number on what this system will cost? Carl From: owner-rv10-list-server(at)matronics.com [mailto:owner-rv10-list-server(at)matronics.com] On Behalf Of Berck E.

Subject: Re: Fuel Return Line Location?
I assume you are aware that leaded fuel such as 100LL will destroy an oxygen sensor in less than one tank of fuel? I seriously doubt that the EFII system and the dual everything required to ensure it has power to work will save enough fuel to have a payback in any reasonable time frame. Mixture management on conventional fuel injection with magnetos is childs play once you get the system delivering equal fuel mixture to each cylinder. While autos are using less gas and producing more power, they are doing it with higher compression ratios, knock sensors and thousands of hours of dyno time. Most of the incremental benefit comes from electronic ignition, not electronic timed fuel injection. Feel free to experiment, but don't expect to get equal power on half the gas, or half the workload, for equal investment. On 4/20/2015 9:55 AM, Berck E.

Don't know. I never used the purge return. The fitting is capped off with an AN cap in the event I ever want to use it. As the plane is flying this must not have been a problem. Taking the plane down for conditional inspection next month so I'll look. I do note that the photos from the Van's Air Force link have the return line further aft than I do. That said, there is no reason not to place the return line fitting more forward on the rib to make sure - like just forward of the fuel sender and about center on the rib. Just make sure you mind the aileron connecting arm.

Subject: Fuel Selector was: Fuel Return Line Location?
Hi Justin, It sounds like you've put a lot more thought into this than I have. I didn't think about a high wing. You're correct, a BOTH position shouldn't be issue. I'd still be concerned, though, about overfilling a tank. Alarms are great when they work, but simplicity is better. The concept of overpressuring a tank with a pump that can put out more than 100 psi is scary to me. Once you overwhelm the vent, what keeps the tank from rupturing? Fuel tanks typically only handle one or two psi before they start to deform. I can practically guarantee you from experience with numerous fuel systems that if you draw from both and return to both, you will fill one and drain one. I've seen it happen a few times. The only explanation I can offer is that I *think* that a small imbalance in vent pressure will bias one tank enough to allow the levels to become very different. Then you'd be working to balance things out, at who knows what phase of flight. Yikes. Thank you for flying those big planes. I'm sure that their designers also craved simpler systems. --Dave On Sun, Apr 19, 2015 at 9:50 PM, Justin Jones wrote: > Dave, > > I understand your concern and welcome any ideas and thoughts that may be > cause for issues.

The wide band O2 sensors will eventually burn out due to lead fowling. They are pricey, and it does not happen in less than one tank of 100LL. There are many guys that have used them for tuning and removed them when they are done with them. Not a good idea to keep them in as they will eventually burn out completely. If you plan on changing your fuel map, I would HIGHLY suggest using a wide band sensor and a display to ensure your AFR (air fuel ratio) is not getting to lean. The stoichiometric ratio for a natural aspirated engine is 14.7:1 It is safer in our aircraft engines to run them at 13.7:1 and thats what the EFII systems stock fuel map is programed to provide. Another indicator of the AFR is EGT, but other things can affect EGT, so the safe bet while tuning is to use a wide band O2 sensor and an AFR gauge to display the correct number to ensure you dont get too lean. The EFII system for me, was a cost benefit to overhauling what I currently had. An RSA5 fuel injection overhaul, new fuel pump, new mags, wires, plugs etc would have been at or above the cost of acquisition of the EFiI system. I have heard nothing but good from this system and Robert Paisley from ProTec Performance has been nothing short of a rockstar with his customer service. I would agree that more benefit comes from the EI than the fuel injection, but by modulating the injectors, they are seeing gains on the dyno with the Electronic Fuel Injection over the mechanical injection. Also of note, the Lycoming hot start issue disappears with the EFII fuel injection. Mixture management is simple with the EFII system due to the programed fuel map they have in the ECUs. It reads the Manifold pressure, RPM, Throttle position sensor, and comes up with the fuel demand for the engine regardless of altitude. There is NO MAF sensor in this system. It uses a similar sensor in the throttle body. If you wish to trim fuel to change the EGTs, you can do so with the mixture rheostat, or you can do it by reprograming the ECUs fuel mapping. Takes some programing knowledge and the software, but its not hard to do. Robert Paisley and or SDS can help with this as well. There is significant fuel savings with this system, but as Kelly stated, it is not half the fuel. Robert has his EFII system on numerous aircraft that race in the Reno air races, as well as many many happy customers flying the complete system. The ECUs are SDS ECUs and have hundreds of thousands of hours tested on them. The fuel pumps
