| Confidence Rating: |  Accident investigation report completed and information captured |
The gyroplane was in the airport traffic pattern when witnesses saw the main rotor head separate in flight and the gyroplane subsequently impact terrain. The pilot’s friends and the mechanic who performed the last conditional inspection reported that the pilot/owner performed most of the maintenance on the gyroplane and that he had recently installed the main rotor head bearing block. Examination of the wreckage revealed that the bearing block had been installed upside down and was being held in place solely by friction. The pilot was not a Federal Aviation Administration-certificated mechanic or repairman.
Probable Cause: The incorrect installation by the pilot, who was not a certificated mechanic or repairman, of the main rotor head bearing block, which resulted in the in-flight separation of the rotor head.
