(Chuck Jensen) ________________________________ Message 1 _____________________________________ Time: 05:42:35 AM PST US Subject: RV-List: Re: Oil leak From: "bluesidedown" Chris, I would be glad to help but the right angle is relative to your installation. The goal though is simple; you want to create at the very least a neutral pressure effect and optimally a little negative pressure for positive crankcase ventilation. What I did for mine was to find a spot on one of the exhaust tubes that is relatively close to the end but free of interference from engine and airframe and not so close the oil doesnt get a chance to burn. I cut a hole in it and then fitted the tube to fit at about a 45 degree angle back and flush with the inside of the exhaust tube gound to fit the curvature. Now some have shown to extend the tube into the exhaust to create a greater effect. I believe with a single tube that would cause restrictions, but with the 4 into 1 collector you could probably get by with it. I really wish I had a dyno an extra engine and some vacuum gauges to put it to science, but I dont. Like anything getting close to or into the exhaust there is the risk of fire. So one should be careful to have enough tube coming out of the exhaust (about 3 to 4 inches depending on airflow) to keep the heat from burning the breather tube and you should replace the breather tube with high temp hose. I used the blue hose from AC spruce and so far no discoloration or sign of stress, so I guess it is OK. I hope that helps. Summit racing and other race shops sell kits to do such a thing and one I found had a screw in weldment which I used on the acrosport. But I did grind off some of the screw in tube to keep it from protruding too much into the exhaust pipe. SO it might be worth looking into too.

Just because it is TSO'd does not mean it will not fail or have software issues. Last spring I borrowed the new factory Glasair Sportsman with dual AFS EFIS's for two months. We absolutely loved the plane and flew it for over 50 hours, including a trip to San Francisco. We only had two problems in the 50 hours that we flew it. The first problems started after the software in the TSO=99d Garmin 430W was updated causing the screen to wash out an d disappear in flight. The second problem happened after we entered the Class B airspace on our San Francisco trip, after about 5 minutes of silence (not much traffic today in the Bay Area?) We noticed that the TSO=99d 430W had f ailed at the worst possible time. The radio was sent back to Garmin for repair and it worked great, until it failed again on Glasair=99s trip to Sun-n-Fun. Anything can and will have problems, you need to have the proper training so that you can recognize and handle the failure. The following is from: _http://www.alexisparkinn.com/nwpilot's_tranatlantic_flight.htm_ (http://www .alexisparkinn.com/nwpilot's_tranatlantic_flight.htm) Then, the G1000 started to go nuts, with the fuel indicators displaying red X's. Next, I received a CO2 detector failure, then GPS-1 failure! At this point I was thinking "What next!?" Well, I didn't have to wait long: The G1000 display suddenly went black, with white text in the left hand corner saying "initializing system"!

So close in fact that the sides of a jam nut cause some interference such that the heim bearing at the top of assembly (the flap arms connected to the handle) cannot go in to the u-shaped holder at the end of the flap arm. If I try to push the bearing over to go into the flap arm the jam nut touches the side skin and does not allow the top bearing to move over any further (if I open up the side skin hole any highe r to clear the nut you'll see it on the outside of the airplane, ugly). This is easily remedied by removing the jam nut and, since the pushrod tube move s away from the side skin as the flaps are extended, there is never an interference issue. I made the pushrod tube long enough that there is no way it will ever spin off either heim bearing and I do have a jam nut at th e top of the tube (at the flap arm). My only concern is whether the jam at th e bottom is needed for extra strain relief on the pushrod tube. If you recall, this is a thick wall aluminum tube that is threaded to accept the heim bearings. Without the jam nut on the bottom bearing, all the stress goes into the threads inside the tube. Whereas if there is a jam nut on the bearing, some of the stresses are transferred to the entire wall thickness of the tube. It would seem that having the jam nut on might help stave off a failure of the pushrod tube that might occur without it. But....don't know if I'm splitting hairs here. Is that what the jam nut is for? Will there be a premature failure at that end of the tube if there is no jam nut ? Or...can I just fly without it? Thanks.

All it does is provide a higher level of confidence that the software was correctly coded such that is works according to the specification provided by the system designer. But, it provides no guarantee that the software specification is in fact correct. I know of multiple occassions where systems with DO-178B Level A (the highest level) software had major software faults (HUD showing pitch and bank in the wrong direction, fly-by-wire software crashing, etc) - not because of software coding errors, but because the software spec did not foresee all possible operating scenarios. TSO approval and DO-178B software cert are useful benchmarks, but it is only with many units in service for many thousands of hours that we start to develope confidence that the units are trustworthy. Assume that any device will either fail, or worse, that it will mislead you. This assumption is important no matter what approvals the device has. -- Kevin Horton RV-8 (Flight Test Phase) Ottawa, Canada http://www.kilohotel.com/rv8 ________________________________ Message 12 ____________________________________ Time: 12:45:31 PM PST US From: Kevin Horton Subject: Re: RV-List: IMC - What If??? Bert - there are so many different reasons that an EFIS could fail, or mislead you, that you should simply assume that it could occur. This is true whether they have done lightning tests or not. Don't bet your life on it not failing. Have suitable backups installed, and be ready and capable enough (i.e. proficient to use the backups in real IMC conditions) to use them.

HOWEVER, fuel dripping down will slowly soften, then dissolve the RTV over time. Type B Proseal (what Vans sells) would be a better choice considering the sealant's exposure to gasoline. I often use gasoline to clean RTV off of various auto engine parts. RTV should never be used on fuel system components.

I'm working on a plan to mount it off the baggage compartment bulkhead with a mount that moves it up into the can opy and about 8" to 10" forward so it's about 12" to 18" or so up behind th e passengers head.- SHOULD have a good view of the sky and yet be out of the way with the display sent to my EFIS units. Any other thoughts where to mount this?- Has anyone done this yet so I don't have to re-invent the wheel?!?- Thanks..... -- David W.

From: "Chuck Jensen" One data point. Pair of GRT EFISs in a Velocity. 410 hours, almost 10% doing some level of IFR and not as much as a hint of a glitch...of course, that says only a little bit about the likelihood of problems tomorrow, but a set of mechanical AS, Alt, TT A/P and an MCI LifeSaver w/battery backup...not interested in challenging Mother Nature or Fate.
