NTSB Narrative Summary Released at Completion of Accident

The certificated commerical pilot was landing a tailwheel, tundra tire-equipped airplane on a dry, paved runway. During the landing roll, the airplane veered slightly to the left. The pilot added right rudder to correct the veer, but this action had no effect. The airplane ultimately ground looped to the left, and both main landing gear collapsed. The right wing struck the surface of the runway, and sustained substantial damage. .

NTSB Probable Cause Narrative

The pilot's inadvertent ground loop during the landing roll.
