The initial story on this thread is eerily similar to an experience that I had with a Hangar 9 Easy 2 a couple of years ago.

I was working with an advanced student, near solo. He asked if he could do a roll (about 2 mistakes high). I watched him do the roll and stop at inverted. The plane was descending while inverted, so I suggested to him that he continue the roll. At that point he told me that he never intended to stop the roll. I took the plane back, and the ailerons had no effect. I figured 'no problem' and went to do a 'split s' out of it. When I pulled back on the stick, the plane did a quarter loop until it was pointed straight down and then stayed that way until it hit the ground. It was a total loss.

I felt horrible about the whole thing, but it bugged me that I could not find out the cause of the crash. It's actually the only crash I've ever experienced where I could not find a plausible cause. The radio appeared to work fine when we dragged the remains back to the bench, and we could not reproduce any condition where the aileron or elevator servo did not work.

I ended up replacing the trainer myself (because there was a family of 5 kids sharing the plane, and I wanted to get them in the air again.) I also suggested that they call Hangar 9 to see if they had any ideas. Hangar 9 went ahead and replaced the airframe with a new one. Unlike the original poster, I was thrilled that they would make this gesture. As far as I know, both planes - the replacement that I gave them, and the one that Hangar 9 gave them - are still flying to this day (the kids soloed, so I don't see them out at our trainer nights very often.)

I've recommended Hangar 9 planes many times since then as a result of their level of customer service on this incident. I guess that puts me into the camp of folks that believe the original poster's expectations are unrealistic...
