What happened
The pilot performed a wheel landing on an off-airport gravel bar measuring 1,500 feet in length and 100 feet in width. During the landing rollout, the nose of the aircraft swerved to the right. In an attempt to stop the airplane quickly to facilitate a short turnoff, the pilot applied the booster brakes. This application caused the nose to continue moving to the right, resulting in a ground loop.
At the time of the accident, weather conditions were characterized by calm winds. The aircraft sustained substantial damage to both wings and the empennage. No injuries were reported.
