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 shortly after touching down in the tail wheel equipped airplane, as the tail was settling the airplane encountered a gust of wind from the right. The right wing lifted and the pilot was unable to maintain directional control, which resulted in a ground loop. The left main landing gear collapsed, and the left wing was substantially damaged. The pilot reported there were no mechanical failures or malfunctions that contributed to the accident.
