Sequence of events

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 pilot was practicing take-offs and landings and described that during the landing flare, a gust of wind pushed the airplane toward the left side of the runway. The airplane’s left main wheel then encountered snow on the side of the runway that pulled the airplane to the left. When the airplane’s nose wheel hit the snow, the airplane nosed over. The vertical stabilizer and both wings of the airplane were substantially damaged. The pilot reported that there were no mechanical malfunctions or failures of the airplane that would have precluded normal operation.
