Aircraft involved
Probable cause & findings
The pilot’s failure to maintain directional control of the tailwheel-equipped airplane during a gusty crosswind landing.
Factual narrative
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.
