The NTSB's narrative final · quoted from the NTSB record
The certificated private pilot was landing a tundra tire, tailwheel equipped airplane, on a paved dry runway. The pilot stated that the touchdown and the landing roll were uneventful, until the airplane's nose veered slightly to the left. He said he compensated by applying right rudder, but the airplane suddenly ground looped to the left. He stated that the right main landing gear collapsed, and the right wing collided with the runway during the ground loop. The airplane sustained substantial damage to the right wing, and right wing struts. The pilot noted that there were no preaccident mechanical anomalies with the airplane.
