(Barry Hancock) ________________________________ Message 1 _____________________________________ Time: 01:24:37 AM PST US From: "Mark Jefferies" Subject: Yak-List: directives --> Yak-List message posted by: "Mark Jefferies" Ladies and Gents. ref directives 59/60 & 107. These directives and other have been sanctioned by the designers and manufactures. 107 is fitted at new production from 1991 onwards. The design of this is to reduce fatigue stress in the wing attachments. With due respect to Dennis the majority (95%) of the a/c we purchase from the military clubs in the FSU all have the "training springs" fitted. This would tell me that the majority of a/c do NOT spend 50% of there life doing aerobatics. Have you tried with these springs fitted?? Its like going to the gym!!! 107, is NOT MADE from stainless steel(yak-52.com), its a post production heat treated high carbon steel, further you do not have to "bring in FSU labour" to fit it!! Well perhaps if your a lone pilot and the maintenance people you use cant read or don't have metric hand tools! If you were to purchase the directive from a reputable source you would get the full fitting instructions in English along with a list of the tools required, basically standard work shop tools along with a portable magnetic drill stand is all that's required. (this can be hired at tool outlets) The time taken to do the job usually is between 98 & 103 hours, from fly into workshop and fly away, wing off, tanks out gear off, works then reassemble. Only minor local painting of the strap is required. We sell the parts for approx $800. If readers wish to take more of an interest in the directives on the YAK 52 you may view pictures of before/ after at www.yakuk.com/mpd.htm This page also lists directives introduced by the UK CAA and LY CAA. Have in mind that all directives have been promolgated as a result of accidents and failures, ie they improve the integrity and safety. It really is burying your head in the sand by ignoring them because the experimental nature of certification in the USA allows you to do so. Still maybe its part of the adrenalin rush by cheating death every time you fly. If anyone wishes to discuss these matters further please feel free to call by phone, +44 1767 651156. best regards, mark. --> Yak-List message posted by: "Rick Swanson" Can anyone tell me what the spar bulletins 59, 60, and 107 are? I assume one of them has to do with the spar mod for the older spars to maintain the 7 G limitation, but haven't heard of any others. Thanks. Rick Swanson 7078Y Ron, You are correct about 59 and 60. They were to maintain the +7, -5 G limitations. 107 is a stainless steel spar strap on the bottom of the wing spar and easily seen under the wing that was to "increase the service life of the airframe to 5000 hours". Please understand though that this service bulletin (107) was based on the airplane spending 50% of it's life in hard aerobatics. We simply don't fly these airplanes that way. Quite frankly, we baby them by comparison to how they were flown and treated in the former soviet union. There is one other SB, 66, that concerns the front and rear wing attach bolts, increasing them to 8.5 mm. If you will go to my web site, www.yak-52.com, and click on the Service Bulletins page, you will find a list with a description statement for each.

Dennis Savarese" Subject: Re: Yak-List: directives --> Yak-List message posted by: "A. Dennis Savarese" Thank you Mark for your insight. I believe I said BASED on 50% of their life. I did not say they DID spend 50% of their life. Either way, I thank you for sharing your information and knowledge with me and the group.
