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 after the airplane touched down on the runway, it encountered a strong wind gust at a groundspeed of about 25 mph, which lifted the left wing and tail. Subsequently, the right wing struck the ground, and the airplane nosed over, which resulted in substantial damage to the right-wing lift strut. The pilot reported no preimpact mechanical failures or malfunctions that would have precluded normal operation. At the time of the accident, the pilot was landing on runway 33 with wind variable from 250° to 270° at 10 knots, gusting to 26 knots.
