Aircraft involved

Probable cause & findings

The pilot’s loss of directional control on landing roll out, during variable wind conditions.

Factual narrative

The pilot of the tailwheel equipped airplane reported that he had been approved by air traffic control (ATC), to enter the traffic pattern for runway 11. On final approach, ATC advised the pilot that the wind had changed, and suggested a straight in approach to land runway 02. The pilot accepted the suggestion and clearance to land runway 02. The airplane touched down on its main landing gear and as the tailwheel settled to the ground, the tail “was pushed around.” The airplane ground looped and came to a stop in the grass beside the runway. Once on the ground, the pilot noticed that multiple windsocks on the airport were displaying different wind directions and suspected the airplane had encountered a strong crosswind. The left wing sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation.
