According to the pilot, he was completing a local sightseeing flight with friends. The weather was "clear and calm." He was cleared for a three-mile straight in approach to runway 7. Following a normal, stabilized approach, a "small bounce" occurred after the initial touchdown. The airplane deviated to the right and he corrected back to the left. The airplane then ground looped and came to rest upright in the grass, adjacent to the runway. An inspector from the Federal Aviation Administration examined the airplane and confirmed substantial damage to the right wing. The pilot reported no pre-impact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
