Aircraft Accident/Incident Report

Gerlach, Nevada 89419
Saturday, September 1, 2001 18:30 PDT

NTSB Narrative Summary Released at Completion of Accident

After turning downwind following takeoff, the gyrocopter lost forward speed and began to descend. It touched down on the left tire, rolled over, and the main rotor blades contacted the ground. The pilot reported there was no mechanical malfunction. He stated the engine and propeller combination was not providing sufficient performance to operate the gyrocopter safely, and he had been modifying it since it was built 2 years previously. This was the second flight of the day after he had shifted the occupant seats to provide better airflow to the propeller.

NTSB Probable Cause Narrative

The pilot's inability to maintain altitude because of the gyrocopter's inadequatly designed performance capability.
