(Mark Schrick) ________________________________ Message 1 _____________________________________ Time: 01:18:30 AM PST US Subject: Yak-List: Re: Yak-52 heavy spar From: "aeroconcept" The issue of bulletins is quite less complicated than it sometimes appears to be. In fact, the complete lists are available from Yakovlev. For me, I have translated and put them on my Web site years ago this is where one realizes that his referencing is probably not optimized, euh Anyway, take a look at: http://www.aero-concept.com/Pages/Pages_reserved/52_pages/52_SB.html http://www.aero-concept.com/Pages/Pages_reserved/50_pages/50_SB.html These lists are quite self-explanatory. I would not attempt to range them according to their importance. The lettering comes from the history of their implementation, with E-bulletins clearly concerning the changes in documentation only. Anyway, for Yakovlev they are all applicable, hence have to be implemented during OHs at the Yakovlev certified facilities, the meaning of certification. One remarks that the lists have the serial numbers concerned. For instance, the famous 59R/60R couple was introduced in production at Bacau somewhere in mid-1986, theoretically starting with # 866501, although I know of some later 1986 serials that were still manufactured with the light spar. The reason is the discrepancy between the times of manufacture of the airframes and of the finished aircraft, i.e. some earlier manufactured airframes were completed later than others. It may be less easy to judge ones aircraft compliance. After checking your serial against the SB list, the next step is to check the original (Russian) airframe logbook which lists all SBs applied during overhauls. Unfortunately, this can not be enough. I agree that some of the logbooks have been faked or incomplete, hence a visual check can be necessary, starting with the most known 59/60 and 107. If you have any problems in reading the logbooks, feel free to send me copies of relevant pages, for second opinion. I do have a list of bulletins for Yak-55, I will put it on my site in near future. In between, I can send them individually on request.

However, could you please respond with what was found to be wrong with the aircraft in the past that prompted the respective SB? I have not found in your past posts any descriptions of what was found. Again, I do not question their validity, I just would like to know the failure mode(s) for inspection/maintenance as well as educational purposes. I am assuming that your discussions with Dimitry Dratch and co. would have given you access to this information.

From: "Pilot5517" Hello, it looks like the Yak 52 I was interested in has had an offer placed on it before I had the chance. This being said I'm curious if anyone knows of another for sale? I'm looking for a 1990 and up - preferably with a Grey/White camo scheme but will take a look at others as well.
