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 conducting a full stall (3-point) landing in the tailwheel-equipped airplane. The pilot reported that after touchdown a wind gust from the right caused the airplane to roll left and ground loop. The fuselage and left wing were substantially damaged during the ground loop when the left landing gear collapsed. Based on the reported wind direction and speed at the airport, there was likely a right crosswind component of about 6 to 9 knots at the time of the accident. The pilot reported that there were no preimpact mechanical malfunctions or failures that would have precluded normal operation of the airplane.
