NTSB Narrative Summary Released at Completion of Accident
The pilot of the tailwheel–equipped airplane performed a short-field landing on the grass runway. During the landing rollout, he applied the brakes and the aircraft slowed normally. Due to his position in the cockpit, the pilot could not see the end of the runway until the airplane approached it. He intentionally ground-looped the airplane in an attempt to avoid traveling off the end of the runway. The airplane turned 90 degrees and impacted trees. According to a Federal Aviation Administration inspector, witnesses reported the airplane's approach speed was excessive for the short runway. Examination of the airplane revealed substantial damage to the forward left wing spar. The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause Narrative
The pilot's excessive airspeed during the landing, which resulted in his decision to perform an intentional ground loop to avoid a runway overrun.
