Narrative:
According to the pilot, upon touchdown, the tailwheel equipped airplane immediately 'lurched' right. He said that he tried to correct, and the airplane initially veered left; however, it ultimately veered right followed by a ground loop. The airplane sustained substantial damage to the left wing. The pilot stated that neither occupant was actuating the brakes at the time of the landing.
A post-accident examination revealed that the tailwheel locking pin was sheared, which allowed the tailwheel to rotate freely more than 90°. When the pin is not engaged, the fork would have the ability to rotate and pivot independently of the steering arm and rudder input, a condition known as free-castoring.

Probable Cause: The pilot's loss of directional control upon landing due to a sheared tailwheel locking pin.
