We have scrapped one a/c beyond economic repair (We have to adhere to OEM lives in UK for all items) and another a/c we have put new spars in. Other a/c have minor spar corrosion. Spars should be checked on an annual basis for exfoliation. With tank panel skins and all inspection panels removed, inc the fabric patches in front of the ailerons with a mirror the whole spar can be seen. Also externally look along the spar rivet line to see if any wing skin is being push up and bulging, this is a sure sign of a problem below. Hope you don't find any but it really IS POSSIBLE. Why do you think YAK 50 system pipes leak after approx 20-25 years and yet this problem does not happen on the YAK 52? I believe the same answer is the cause of the spar corrosion in the 52.

    --> Yak-List message posted by: cpayne@joimail.com Once upon an airshow, I took a few current AF & Navy IP's up for a hop in the CJ 'twix lulls in the schedule. Waivered airspace but "approved" for military IP's as backseaters. These guys flew in to the show with T-34C models out of Pensacola along with their students but couldn't participate with the assets. They love CJ-6's and Yak-52's for their handling and load limits. With the Charlie model T-34, each training hop was strictly regulated on the training syllabus with a G limit, never more than 3.5 G except for specific hops to 4.5. Not only did they have to record and sign the dial meter log, but there were fixed load cell devices on the airframe for maintenance to check. We pulled some G's with exaggerated duster turns up/down the crowd line, they loved it. I'm not sure if the new Texan T-6A is on the same sort of fatigue life schedule but I would not doubt it.

OK, I am going to play devil's advocate here. First, remember that all-important quotation, "Never attribute to malice that which may be adequately explained by stupidity." OK, substitute "ignorance" for "stupidity." Any discussion of safety begins with a statement of fact. WBM did that. I then propose to you that they didn't have any more information nor did they have the background to even begin to offer a suggestion of a solution. I don't think that their article was malicious. I think they stopped at the end of what they knew which is what they should have done. Now here is another idea. Consider what it looks like to the rest of the warbird community when we erupt like a struck hornet's nest when WBM publishes an article of fact. We start accusing people of all sorts of mischief when the right answer would be to produce the follow-on article that shows that RSPA is dealing with the issue. So quit bellyaching and do something. Or just quit bellyaching. > If I remember correctly, the Russians use a G-limit that is 50% of > structural failure (of a NEW wing). I don't recall what the Chinese > used...Pappy?

I think both people were saying the same thing. Barry was saying that the design load factor was set at 50% of the yield point for the wing structure. That means if the wing failed at a simulated load of 12G, the design load factor is set at 6G. When Gus says that the Russians use 100% he is stating the same thing; that the failure point is 100% greater than the design load factor, i.e, if the wing has a design load factor of 6G, it will not fail until 12G has been placed on the structure. Percentages can be confusing. -- Brian Lloyd 6501 Red Hook Plaza brian@lloyd.com Suite 201 http://www.lloyd.com St. Thomas, VI 00802 +1.340.998.9447 (voice) +1.360.838.9669 (fax) There is a time to laud one's country and a time to protest.

    Subject: Re: Air fitting
    --> Yak-List message posted by: "DaBear" <dabear@damned.org> Frank, The great thing about using a scott bottle is that just about every fire station in the US has a way to fill them. So if you land at some airport without an FBO, the local fire department can help fill your bottle. They also hold about 2300psi. Btw, the K bottle system you mention still has to be "bastardized" to fit in your system just like a scuba bottle or a Scott bottle, so I don't see any additional value there. Am I missing something?

    Subject: Starting system
    --> Yak-List message posted by: "Jorgen Nielsen" <jorgen.nielsen@mweb.co.za> On the off chance that some of you guys out there might one day have the same problem that I have had the last 7 weeks or so, I thought I would share this. 7 weeks back my Yak52 refused to start. No prior warning, but in hindsight I had battled with her somewhat, leading up to the failure to start. Tried a few times, ran out of air, filled up, tried again, etc. Eventually got her running by starting with mags. I was in the middle of some training, so carried on like that for a couple days. Very hit & miss, cause she would fire and run backwards. Then run out of air, so switch off, unstrap, open hangar, get air bottle fill up, put air bottle away, close hangar, try again, repeat from start. You get the picture. Then I had to give a friend a lift and got stuck at a remote airfield. Not nice. So my mechanic came out to fix it, determined it was the HT lead going into the mag. Wire was burnt, wire a smaller diameter than the hole, so difficult to get good connection. He fixed (we thought). Tried start, turned on mags after couple blades, she ran. Flew back home. Next time I tried start same problem. By then my mechanic had left to go assemble some jets somewhere, so I had to fix myself. Since then I have dismantled my No. 1 mag at least 7 times. I can do it with my eyes closed. The safety wire I now cut off without even measuring and its the perfect length. I have re-engineered the HT cable going into the mag several times. I have re-sleeved the HT lead from the starting coil on the chance it was arcing to metal conduit where it enters the mag. Twice. I have replaced the leatheron the metal mag cover with silicon sheet, on the chance that the spark was arcing to the cover. BTW I now have a very sexy mag cover, artificially augented with silicon I know, but very sexy nonetheless. I have built an extension to the wire with different diameter wire to ensure a good connection. I have electrocuted myself several times to prove the connection (Yaks not for sissies). With all my starting attempts, I am now also on first name terms with the local dive shop who fill up my cylinder. But would she start - no way. I have hand propped her myself, securely chocked, with my 10 year old son Chris in the cockpit handling the priming and mags, in order to go fly. He had instructions that if after she fires he doesn't see me, or he sees me flying through the air, or he sees blood to switch the engine off. BTW he does a nice aileron roll now, a bit slow, but OK. Anyway, my dimwitted brain eventually told me to look elsewhere. A clue was getting a lovely 12mm blue spark from the contact inside the distributor to an earth cable I made up, complete with croc clip on one end and a plastic (non-conductive) handle on the other. Pain makes one learn fast. I had decided on the weekend just past, to swap out the rotor and distributor, so took a spare mag apart, took home the rotor and distributor and cleaned it like new. Even dried it in the warmer drawer when my wife wasn't looking. Went tonight after work to fit it, then decided to swap the rotor first then close up and attempt start, on the basis that its a big job to swap all the HT leads, and I wanted to do one thing at a time to find out where the problem is. BTW, I don't have power in my hangar, so this was all done with 2 camping lights running off a 12v battery. Finished the swap, pulled her out the hangar, primed etc., and hit the start button. The prop hadn't even rotated one blade and she was running. Warmed her up, shut down, tried again, same thing. Mag drop normal. No problem. Life is good. I am going to fly the crap out of her this weekend. So, to summarise the lessons learnt: If she doesn't start, pull the cover off the mag. Make a test lead as described, make sure there is no air in the system with the air valve closed. Then make sure again there is no air in the system. Squeeze brakes, flaps, etc. Then get your 10 year old or any passerby to hit the start button. Holding the test lead near the pin that transfers spark to the rotor, check for spark. If none, then its either your HT lead from the starting coil (shower of sparks), or the coil itself (or some LT wiring problem, which one can find with a meter). If HT, replace wire or starting coil as appropriate. If there is a strong spark, the problem is either a short to the mag cover, or some other problem downstream. Assuming the motor runs on the mag as mine did, one can assume the HT leads to the plugs are all OK. Therefore the problem has to be the the transfer of spark to the plugs, i.e. the rotor, or perhaps a crack in the distributor close to the starting wire, but most likely the rotor. And this was my problem. No faults on the rotor are evident when testing with normal meter - I had tested it previously, so was convinced it was the HT wire coming from starting coil, where it goes into the mag. On my rotor, there is continuity from the ring pickup to the trailing (retarded) pin, so the problem with the rotor has to be a short to earth that only occurs under high voltage, which I have no way of testing. The rotor I swapped without re-timing the mag, by making a cardboard template that I secured to the mag, moving the prop to line up the rotor to the best position (which was with the main connector pointing forward), and marking the position of the rotor with pen on the cardboard. Put the new one on in exactly the same position. Be careful you don't move the prop during this, and be careful there are no paralax errors when checking position. So, now all OK. Bear in mind I am not a mechanic, and I am sure you experienced guys out there may have better ways and tools of diagnosing and fixing these faults, but I don't so it was a lot of trial and error. This turned out to be quite a long post. Hope it helps someone, sometime. Any corrections, suggestions, please make them. Jorgen

    Subject: Re: W&B, fuel tanks
    --> Yak-List message posted by: "Ron Davis" <l39parts@hotmail.com> Fuel transfer problems aren't unique to Nanching. Cessna's have a long history of glitches- 310s pump fuel overboard, 208s have uncommanded transfers, etc. If you think fuel transfer is problematic you better sail home from Nigeria. Boeings, and especially Douglas DC-10s have complex fuel transfer schemes (Shall we pump some fuel up into the tail now, captain?}. The Concorde, to cite an unsucessful airliner, also transfered fuel to stay in CG. Sure pumps fail sometimes, but the most common fuel transfer failure is the pilot forgets to ____(fill in the blank)_____. If you can't get the knack of it, there's always the Cub or Champ: One tank, no valves.

    Subject: Re: cu.in.
    --> Yak-List message posted by: "Ron Davis" <l39parts@hotmail.com> There are 16.387 ccs in a cubic inch, so if your dodge is a 318 cu in, it has 5211 cc. I wouldn't bet that 318 or 5.3 L is completely accurate.

    Subject: Re: Wing Fatigue
    --> Yak-List message posted by: "Ron Davis" <l39parts@hotmail.com> Theoretically, any metal will fatigue as Marshall stated. If you have some time get a piece of aluminum foil from you kitchen and deflect it 10 degrees up and back until it fails. I'd like to know this number, but don't have time to do the test myself. Certified transports in the U.S. have to do those tests to determine wing life. They do it while the fleet is flying because they don't want to do 20 or 30 years of testing before they deliver the first plane. The communists turned out to be smarter than Nixon told me they were when he sent me to Vietnam. Cheng Bushi designed a very good plane and since the others haven't been falling out of the sky, yours probably won't either. If you really need something to worry about, then worry about a Beech falling on you. This product of American ingenuity has spar ADs on the 1940s vintage D-18 through the 1990s vintage King Airs, and lots of things inbetween. You can get a really good deal on a T-34 right now. Beech should offer Mr. Cheng a job.

    Subject: Re: RE: parachute
    --> Yak-List message posted by: "Ron Davis" <l39parts@hotmail.com> Zeman, The aircraft is legal to fly if it has an airworthiness certificate issued in accordance with the FARs. The last part of FAR 91.307 says: (e) For the purposes of this section, approved parachute means-- (1) A parachute manufactured under a type certificate or a technical standard order (C-23 series); or (2) A personnel-carrying military parachute identified by an NAF, AAF, or AN drawing number, an AAF order number, or any other military designation or specification number. I read it. I don't see where it says the chute is ok in a CJ. Please explain it to me. Please explain also how "it helps that the plane is designed to have a chute at all times. No, my seat cushion isn't TSO'd. Please tell me the FAR number that says it has to be.

    Subject: Re: so...
    --> Yak-List message posted by: "Ron Davis" <l39parts@hotmail.com> I didn't know our trade barriers were subtle. I'll be ordering the CD from you. I'm sure the chutes are good. It would cost a lot to get them certified, and if I, for example, did the certification, I'd need to charge a lot for the ones I sell to get the money back. I could also sell an STC for people whe already own the same model of chute. Sort of like translating foreign documents... We have to pay for an STC to make a (certified) American plane legal to burn auto gas. It's just a bureacratic thing. Should I assum you don't have such obstacles in the U.K.? I don't care if people use Russian chutes. I think they should be aware of the of the regs and then if they choose to ignore them, so be it. It's no hazard to me, and therefore clearly none of my business. A case made for protecting the ignorant public that rides in a CJ, and deserve the full protection afforded by a certified chute, but I don't buy it. I hope your sales make the effort you invested worthwhile.
