Primary finding
Probable cause
The pilot's failure to maintain directional control while landing in gusting wind conditions, which resulted in a ground-loop.
Investigator assessment
Analysis narrative
The pilot reported that during the landing roll, the airplane encountered a wind gust from the right, which caused the airplane to weathervane to the right. He said that due to the airplane's slow speed, left rudder was ineffective, and by the time he applied left brake the airplane had ground-looped. The left main landing gear collapsed, and the left wing sustained substantial damage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
