Incident Overview
During the landing roll, a tail wheel-equipped airplane ground looped, causing the right main landing gear to collapse. The pilot had observed the airport's windsock while entering the traffic pattern, which indicated a variable wind of 10 to 15 knots.
Sequence of Events
Approximately halfway down the runway during the landing roll, the airplane encountered a gust of wind. The gust contacted the tail, causing the airplane to veer to the right of the runway centerline. The pilot attempted to regain control, but the right main landing gear collapsed, and the right wing contacted the terrain. The airplane subsequently came to rest off the right side of the runway.
Mechanical Status
The pilot reported no preimpact mechanical malfunctions or failures with the airplane or engine.
