| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot was maneuvering the helicopter at low altitude to conduct a cherry-drying operation. A witness in the local area reported that the helicopter was flying near power lines when it made a steep left turn. The main rotor subsequently impacted the power lines, and the helicopter descended into a tree. The pilot sustained serious injuries and did not recall the accident sequence. He did recall that the helicopter had no mechanical issues before liftoff or during transition to forward flight. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
Probable Cause: The pilot’s failure to adequately monitor the environment and maintain clearance from the power lines while maneuvering at low altitude.
