Sunday, May 26, 2002 10:24 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot of the gyrocopter had conducted several touch and go's on the runway. On his last approach, he aligned the gyrocopter with the grass apron, and elected to continue on his heading to land on the grass adjacent to the runway. Witnesses described the approach as "fast" and "odd" and that the gyrocopter pitched nose-down before hitting the ground and rolling over. The pilot had 200 hours of flight experience. He did not possess a rating or a student endorsement for rotorcraft/gyrocopter, and had no experience in make and model. The pilot reported that there were no mechanical anomalies with the gyrocopter.

NTSB Probable Cause Narrative

The pilot's improper flare prior to touchdown. A factor was the pilot's lack of experience in aircraft type, make, and model.
