Incident Overview
According to the aircraft owner, a pilot was being checked out on the aircraft when a ground loop occurred during landing. The aircraft rotated 180 degrees during the event. The side load imparted to the tail section tore the tailwheel off the empennage at its attach points, resulting in a bent bulkhead.
Pilot's Account
The pilot stated that the accident happened when directional control was lost during the landing rollout. This led to a slow right turn, during which the airplane exited the runway. The aircraft came to a stop approximately 20 feet from the runway edge, facing the opposite direction.
Mechanical Condition
According to the pilot, there had been no previous mechanical failure or malfunction with the aircraft or any of its systems prior to the accident.
