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 landing on runway 20 with a right quartering headwind of 7 knots, with gusts to 19 knots. The pilot reported that, as he was making a left turn to enter a taxiway, a gust of wind raised the wing before he lost directional control. The airplane then impacted a runway marker sign, causing substantial damage to the right main landing gear, right side of the fuselage, and the propeller. The pilot reported that he was not injured and exited the airplane unassisted. The pilot also reported that there was no mechanical malfunction or failure with the airplane. The Federal Aviation Administration inspector who responded to the scene and examined the airplane reported that there were no anomalies with the brake system, tailwheel steering, or flight controls.
