    Subject: Official Usage Guideline [Please Read] [Monthly Posting]
    DNA: do not archive --> Yak-List message posted by: Matt Dralle <dralle@matronics.com> Dear Lister, Please read over the Yak-List Usage Guidelines below. The complete Yak-List FAQ including these Usage Guidelines can be found at the following URL: http://www.matronics.com/FAQs/Yak-List.FAQ.html Thank you, Matt Dralle Matronics Email List Administrator ****************************************************************************** Yak-List Usage Guidelines ****************************************************************************** The following details the official Usage Guidelines for the Yak-List. You are encouraged to read it carefully, and to abide by the rules therein. Failure to use the Yak-List in the manner described below may result in the removal of the subscribers from the List. Yak-List Policy Statement The purpose of the Yak-List is to provide a forum of discussion for things related to this particular discussion group. The List's goals are to serve as an information resource to its members; to deliver high-quality content; to provide moral support; to foster camaraderie among its members; and to support safe operation. Reaching these goals requires the participation and cooperation of each and every member of the List. To this end, the following guidelines have been established: - Please keep all posts related to the List at some level. Do not submit posts concerning computer viruses, urban legends, random humor, long lost buddies' phone numbers, etc. etc. - THINK carefully before you write. Ask yourself if your post will be relevant to everyone. If you have to wonder about that, DON'T send it. - Remember that your post will be included for posterity in an archive that is growing in size at an extraordinary rate. Try to be concise and terse in your posts. Avoid overly wordy and lengthy posts and responses. - Keep your signature brief. Please include your name, email address, aircraft type/tail number, and geographic location. A short line about where you are in the building process is also nice. Avoid bulky signatures with character graphics; they consume unnecessary space in the archive. - DON'T post requests to the List for information when that info is easily obtainable from other widely available sources. Consult the web page or FAQ first. - If you want to respond to a post, DO keep the "Subject:" line of your response the same as that of the original post. This makes it easy to find threads in the archive. - When responding, NEVER quote the *entire* original post in your response. DO use lines from the original post to help "tune in" the reader to the topic at hand, but be selective. The impact that quoting the entire original post has on the size of the archive can not be overstated! - When the poster asks you to respond to him/her personally, DO NOT then go ahead and reply to the List. Be aware that clicking the "reply" button on your mail package does not necessarily send your response to the original poster. You might have to actively address your response with the original poster's email address. - DO NOT use the List to respond to a post unless you have something to add that is relevant and has a broad appeal. "Way to go!", "I agree", and "Congratulations" are all responses that are better sent to the original poster directly, rather than to the List at large. - When responding to others' posts, avoid the feeling that you need to comment on every last point in their posts, unless you can truly contribute something valuable. - Feel free to disagree with other viewpoints, BUT keep your tone polite and respectful. Don't make snide comments, personally attack other listers, or take the moral high ground on an obviously controversial issue. This will only cause a pointless debate that will hurt feelings, waste bandwidth and resolve nothing. ------- [This is an automated posting.]

Last year I flew up to MTW/OSH with one of those "simple nose gear fairings". It worked...BUT, it causes a LOT of drag in the gear down position and could compromise a go-around with a stock 285 on a high density altitude day. Great speed brake though. Currently I'm working on more "stuff", see it at SNF, my airplane will be the one with areas of paint stripped as I slowly remove it in my spare time. Retirement is such hard work! :) Craig Payne

    Subject: Hooker harness installation
    --> Yak-List message posted by: <lie.buyse@pandora.be> Yakkers with aerobatic style Hooker harnesses, After receiving my harness, I see that the seat belt consists of a DOUBLE strap (no pictures on their website!). Questions : - belt with ratched must face rearwards (so on the left side) with the attachment on the seat pan? - "front" belt attachment point somewhere on the airframe or on the seat pan together with the former one? - shoulders straps and crotch strap to be clicked on the same strap? the front or the rear one? or maybe shoulders rear and croth front? Thanks for advise, Lieven Buyse Yak 52 RA1428K P.S. : inspect your four wing attachment bolts carefully. Inspector found one with 5 mm crack of irregular shape in the face of the left lower bolt (1990 airframe). No CofA until all four replaced.

    Subject: RPA Newsletters & Bulletins
    --> Yak-List message posted by: Drew Blahnick <lacloudchaser@yahoo.com> Folks, If you recieved the Newsletter and liked the format and layout, or did not, email me directly. Remember, the newsletter is only four times a year, so we've also designed two other full membership "anytime" bulletins; "Hanagar Talk" for all things flying-only related, and "The Oily Rag" for all things Maintenance. These can be sent out on a 24 hour notice if the content requires it. You will be recieving the first Hangar Talk edition immediately after we get back from meetings in Arizona. I'm meeting with the BoD in Febraury and will re-address US Mailed newsletters, at least to those members who choose this, but as always, we need a team-driven level commitment, possibly enlisting regional coordinators to assemble the USPS versions for distribution for their membership. The electronic versions completely wipe out distribution volunteer manhours, and greatly reduced formating and layout; liberating us to focus on your content, but the success and viability is based on having the products recieved by accurate emails and avoiding issues with spam filters that block delivery. We will be resending this first newsletter, most likely, to the membership after correcting/updating the association email list. As I mentioned, we are also sending out the bulletins which, because they are focused content, are excellent reads for those interested in the subject matter. In 2004 we were working on this project and you didn't hear from the RPA enough, now as we mature the program you might hear from the RPA too much, express patience with your volunteers and we all benefit in the end. Website. Yes, it's true; in my efforts to resolve the 600X800 display issue I, Drew Blahnick, the 105 MM Airborne Field Artillery Howitzer "I'm bored fellas, lets go blow sh_t up" pilot, broke the darn website! Not a complicated fix, but Deon is strapped right now with a software project and will bring it back online here shortly. It was sorta like that cartoon of the kid sitting in first class on an airliner curiously about to hit a lighted seat push-button labeled "wings off" Hmmm, wonder what would happen if I do thi... I will stick to basic web design and web content, if you are a web engineer/code designer, and would like to join the team to keep guys like me from blowing sh_t up, email me at admin@flyredstar.org Now there's an effective volunteer sales pitch if I ever heard one...

All whom attended Waycross used a radio gear callout on the break. However, we know based on registration numbers, that about 1/2 of the Yak/CJ owners are NOT RPA members and they may not be aware that there is an insurance problem. Sooo, how do we reach out and communicate with those folks? Perhaps a membership drive of sorts? BTW, yes I know the FAA definition but I define an "incident" as *stuff happens* but an "accident" as somebody screwed up, either in maintenance/preflight or in the air. I regard an "accident" as one of those giant Florida turkey vultures tearing off parts of my airplane, or a tire sinking into an unseen chuckhole on rollout, etc. Craig Payne Craig Payne ________________________________ Message 2 _____________________________________ Time: 04:25:18 AM PST US From: KJKimball@aol.com Subject: Re: Yak-List: how much is a newton? --> Yak-List message posted by: KJKimball@aol.com L39, You are correct.

I've heard from reliable sources about a CJ that took off with pilot and CFI for an unexpectedly exciting and unintentionally advanced instructional flight a couple of years ago. Training is usually a Good Thing, even advanced training, sometimes especially with unexpected distractions thrown in. Except in this case, the fuel strainer drain safety wire had been removed for draining fuel (good idea), but not replaced (bad idea). (I know, you can see it coming already!) The owner/pilot just didn't want to be bothered with safety wire every time he needed to drain a little fuel (a common thought) and I guess the CFI either wasn't real familiar with the airplane (not good) or didn't want to press the point (not good in this case, either). The strainer is located very close to one exhaust outlet. Unfortunately, the drain valve vibrated open in flight, turning the airplane into a gasoline powered roman candle and burning all the paint off the side of the airplane. Fortunately, they had presence of mind to shut off the fuel, which soon extinguished the fire. Only problem was they now had a pretty poor glider on top of an overcast. Yes, they and the airplane survived. More to the point, as you'll soon discover, the CJ's weakest link is the exhaust system. If you get 400 hours out of a new one you're doing well. Since the stock exhaust is made of mild steel, rust, heat and corrosion (inside and out) will soon do their work, especially at pipe joints and intersections, small radius bends and at the ends, leaving you with a perforated blowtorch. Get rid of the stock unit ASAP and get a stainless setup. Don't bother with ceramic coating etc. Get stainless. You can even get a heat muff setup to warm your hands on those cold (summer) days here in the PNW. Cliff makes some very good points. Remember that oil burns, too. Keep it clean and leak-free. I would also recommend that all flexible lines have fire sleeve installed. A little farther afield: A few years ago Fred Ihlenburg (Yakkity Yaks--are they still in business?) used to advertise a CJ with a multi-outlet-pipe exhaust that exited from the side cowling openings (I think Mike Filucci has that airplane now), like a Sea Fury etc. Looked pretty cool. Don't know if stainless etc. was installed to protect the fuselage sides. And I suppose carbon monoxide could have been a problem--maybe not. Understand it was pretty noisy. I've long thought that sealing up the cowling nice and tight, fairing it to the fuselage sides and bottom, along with a simple nose gear strut fairing to close up some of the gear slot and maybe using an exhaust augmenter out the sides would be a good way to speed things up, either with or without inlet vanes. Add a nice spinner and a dishpan to reduce the inlet size. If you just take the vanes off you'll get a nice little speed-up, but excess cooling is a problem (even in summer, esp. here in the frozen north). Resident speed merchant is Craig Payne who can give your more ideas if you're into that kind of thing. And, welcome aboard, hope you enjoy the airplane. Jerry Painter --> Yak-List message posted by: Cliff Umscheid To Pappy and Elmar. Re Fire extinguishing systems: Any fire ext sys you put on a radial engine has to have a means of closing in zones 2, 3 and 4. Characteristically, radials have no way to close in zone 1, which encompasses the nose case. But what do you have to burn out there in zone 1? More than you might think on some big radials with a magnesium nose case, You probably haven't seen a real engine fire which defies extinguishing until you've seen a magnesium fire from a runaway prop in the process of seizing up or flying off the engine.. It is an illuminating experience which is best viewed on a dark night for effect. Further, there isn't much time to get the beast on the ground before it burns through the tin and into the fuel tanks followed by wing failure. Pappy, If you get a zone 1 fire on your B-24, you may recall from some earlier training on a different equipment, the first priority is to Feather because you don't have extinguishing to zone 1 and the only way to extinguish is to feather and dive to blow it out. Feathering is best accomplished at a lower IAS which preceeds the dive. Elmar, I don't know if your CJ has a magnesium nose case, but if you have retained the cooling gills on the airplane you DO have a means of enclosing zone 1. The purpose of enclosure is to keep the extinguishing agent from being evacuated before it can be effective The greatest risk of fire in your CJ comes from the fluid lines in zone 2. Check them frequently for brittleness and stiffness as well as integrity of hose to fitting. Watch for signs of SEEPAGE both through the hose and at the fittings. Contrary to general knowledge, there have been about 5 instances of engine fires in the YAK and CJ series of airplanes. Most of these occurrences are due to failure to change the hoses at proper intervals and/or use of wrong ( spelled AMERICAN ) size hoses with Russian fittings. ( "Looks right"aint good enough here ). Manufacturer's recommendation on the YAK series is all hoses changed every 5 years. Brake lines too! Elmar, Your zone 3 vulnerability ( if CJ is like YAKs } includes the fuel tank area forward of the cockpit, Does your airplane have a stainless steele firewall by way of original manufacture or later modification? In the YAKS this gives you a little more time to get the fire out, or put it on the ground . Don't be too choosey as to WHERE, you don,t have the luxury of TIME. One thing more, check the band clamps securing the flexible exhaust manifolds. With rust comes weakness and porosity. A hole or separation in the exhaust assy. can act as a blow torch on a fuel or oil line. Look for signs of discoloration around the exhaust assy. and related area. You can't see enough with the cowling closed all the time, Take the tin off frequently!

    Subject: Marvel Mystery Oil - again
    From: Stephen Fox <jsfox@adelphia.net>
    --> Yak-List message posted by: Stephen Fox <jsfox@adelphia.net> Ok I know this subject has probably been covered to death, but as a new Yak 52 owner who just finished up transition and who joined the list at the very tail end of the last discussion about MMO. Here=B9s the question add to oil, add to gas or add to both and in what quantities. Thanks, Steve Fox

    --> Yak-List message posted by: "A. Dennis Savarese" <DSAVARESE@ELMORE.RR.COM> Add to oil. 1 qt per oil change Add to gas. 6 oz. per 15 gallons. Be religious about using it too. Interpolate what is needed for each tank each time you fuel up. Available at most Wal-Mart's for $9.84 per gallon. Least expensive place to buy it.

    Subject: Marvel Mystery Oil - again
    --> Yak-List message posted by: Bitterlich GS11 Mark G <BitterlichMG@cherrypoint.usmc.mil> Dennis's values are accurate... just adding my 1 cent. Just in case you ever worry about putting too MUCH in: I have used twice that amount in the fuel for the last 250 hours with no ill results that I can see. I.E., I use about 1/2 quart for every 28 gallons or so, which is way over the recommended dosage. I had rather serious lead fouling on cylinders 9,1 & 2, mainly because the cyl. head temps. are way too cool on my engine ... "why" is another discussion. Suffice it to say that running this high an amount of MMO 'seems' to have cut my lead fouling problems down significantly. This belief has also been supported by inspection of the spark plugs which now have little to NO lead fouling in two years of operation. So if you slip.. and slurp in a little too much... it's no big deal. I put one quart in with every oil change, as Dennis recommends, and when I get close to around 20 hours, I put another two quarts in for one flight... and then drain and change the oil.
