The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The solo private pilot was landing a wheel-equipped airplane at an off-airport, snow-covered site. During the landing roll, the airplane bounced when it encountered a small snowdrift. The pilot said that he attempted to recover but the airplane drifted to the right and nosed over when it touched down in deep snow. The airplane sustained substantial damage to the vertical stabilizer, rudder, and wing lift struts. The pilot said there were no preaccident mechanical problems with the airplane, and noted in his report to the NTSB that he should have selected a better area to land on.
