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 while landing in gusty wind conditions, the airplane drifted to the right before touchdown. As the airplane “hit the ground”, he reduced the engine power, and applied the brakes. Subsequently, he over applied the brakes and the airplane nosed over coming to rest inverted. The airplane sustained substantial damage to the wings and empennage. The pilot reported no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation.
