Aircraft involved

Probable cause & findings

The pilot's failure to maintain directional control of the airplane during taxi.

Factual narrative

The pilot reported while taxiing a tailwheel equipped airplane from the runway, the airplane began to turn left. The pilot applied opposite rudder however, the turn sharpened and he "aggressively" applied the right brake which resulted in a ground loop. The airplane sustained substantial damage to the left wing when the left main landing gear collapsed. The pilot reported no mechanical malfunctions or failure with the airplane that would have precluded normal operation.
