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 touchdown on the runway, a gust of wind pushed the tail of the airplane to the left. The pilot was unable to maintain directional control and the airplane departed the runway and nosed over in a grassy area adjacent to the runway. The airplane sustained substantial damage to the left wing. The pilot reported that there were no pre-accident mechanical malfunctions or failures that would have precluded normal operation. The reported winds about the time of the accident were light and variable at 3 knots.
