Aircraft involved
Probable cause & findings
The loss of control and ground loop due to the mechanical malfunction of the tailwheel lock.
Factual narrative
The pilot of the tailwheel-equipped airplane reported that he conducted several takeoff and landings before the accident that day, at a different airport, all without incident. During the accident landing, the airplane touched down, veered left, and the pilot attempted to correct with right rudder. Subsequently, the airplane exited the runway, the tail veered to the left, and the airplane “rocked” left. The left wing and left elevator impacted the ground resulting in substantial damage. The airplane came to rest upright on the main landing gear and the pilot was able to taxi the airplane to parking without further incident. A witness reported seeing the tailwheel rotating after takeoff. An examination revealed that the tailwheel locking mechanism did not function.
