| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot of the helicopter was flying over mountainous terrain, about 500 ft agl, with moderate wind and turbulence conditions. After he slowed the helicopter to 60-70 knots it suddenly and uncontrollably descended at a rapid rate in a severe downdraft. The pilot maneuvered toward lower terrain to accelerate but was unable to arrest the descent before the helicopter collided with the ground tail first. The helicopter fuselage was substantially damaged. The pilot reported that there were no preaccident malfunctions or failures with the helicopter that would have precluded normal operation.
Probable Cause: The pilot's failure to maintain directional control of the airplane during an aborted landing, which resulted in a ground loop, runway excursion, and subsequent nose over.
