Analysis

The owner, a private pilot, was getting dual instructional training in his tailwheel equipped aircraft. The aircraft was a Piper PA-20 that had been converted from a model PA-22. The owner had accumulated about 10 hours of flight time in this make and model. The accident occurred when the aircraft ground looped during a practice landing. The instructor pilot (ip) reported that the owner/trainee was doing so well with his practice that he (the ip) just relaxed. Reportedly after the aircraft touched down, it was going straight, and the ip thought the plane was under control, when it started to move slightly to the right. The trainee started to correct with left rudder, but the movement to the right continued. The ip then tried to correct the impending ground loop, but was unable. The left main gear collapsed and the left wing was damaged.
