I've flown literally dozens of Easy Fly, Easy 2, Xtra Easy and Alpha trainers from Hangar 9 (last night I flew my first Xtra Easy 2), and just about every other trainer you can imagine as well. I do instruction for our club on our weekly training nights. I've been doing between 150 and 200 logged training sessions per summer for the last 8 years.

I roll trainers all the time (and I am well versed in use of the rudder). The reason that the incident I posted above was memorable to me is that it's the only time I've ever crashed a trainer doing a roll, and I could come up with no reason whatsoever for the plane to do what it did. I never figured out what happened that caused the behavior.

I've crashed about 5 planes since I've been instructing, and in all of the other cases, there was either an obvious mechanical malfunction or - in two cases - a midair collision.

I replaced the plane myself because I felt bad that, even after a post crash analysis, I couldn't come up with a reasonable explanation as to why it was destroyed. This is the only incident I've ever had where I've felt any need to replace a student's airplane.

The reason that I posted to this thread is that I certainly didn't hold Hangar 9 responsible for it. They greatly exceeded my expectations by offering to replace the plane.

Thanks,
