<<<<<<<<<<<<<<<<--->>>>>>>>>>>>>>>> << Lancair Builders' Mail List >> <<<<<<<<<<<<<<<<--->>>>>>>>>>>>>>>> First of all, I would like to thank everybody who responded to my original post with good advice and warnings, thanks much! Furthermore, I am pleased to say that my aileron vibration problems is now in the past and no longer exists, thanks to this forum. After inspecting both ailerons, I discovered that the right aileron (the good one) had a very stiff LE, but the left one was kinda flimsy. I proceeded to stiffen the left aileron with 2-bid along the entire span of the LE and also added a small pre-preg right in the middle section. This mod really stiffened the LE quite a bit. I installed both ailerons this moring and flew... Absolutely NO VIBRATION! Smooth as silk! The plane felt great and I had a fun time flying it this morning. So based on this experience, the following summary: - Make sure that the ailerons are 100% or more balanced; - Make the TE section of the ailerons as stiff as can be (added pre-preg braces and /or more bids if necessary); - Rig the ailerons in the flared position or even a little bit above flared during cruise by adjusting the flap and/or the aileron rod ends. Gee, having solved this problem, another one surfaced today. While doing an emergency gear extention test today (on jacks), I heard some really awful sounds. Apparantly, the TOP phenolic hard point where the main gear hydraulic cylinder attaches separated from the nose gear well. I guess I was lucky again that this did not happen during flight. Obviously, I have to bring out the epoxy pump again and fix this problem but probably add more bids to beef-up this area even more. I do beleive, if I remember correctly, that this was a factory layup, so I don't know how much bids was there to start with. Probably need to look at the manual again to check. Back to work... Thanks again guys, ;-) Rick Argente N360ZR LML homepage: http://www.olsusa.com/Users/Mkaye/maillist.html
