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 reported that upon touchdown on runway 12, the left quartering headwind switched to a direct crosswind forcing the nose of the airplane to the left. The right wing contacted the runway surface and the airplane nosed over, sustaining substantial damage to the empennage, vertical stabilizer, and rudder. Wind at the time of the accident was reported to be from 070 degrees at 12 knots gusting to 22 knots. The pilot stated that there were no preaccident mechanical anomalies that would have precluded normal operation
