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 the tailwheel-equipped airplane on runway 24 with a quartering headwind from the northwest gusting to 20 knots. During the landing roll, the flight encountered wind gusts from the northwest that caused the airplane to “weathercock” to the northwest and the pilot applied full engine power to go around. When the airplane was about 1 ft above ground level, the right main landing gear impacted a taxi light. The airplane then contacted the ground and nosed over. The airplane sustained substantial damage to the left wing and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
