Robinson Helicopter Company R44 II N282MC accident near East Wenatchee, Washington

Probable cause

The pilot’s failure to adequately monitor the environment and maintain clearance from the power lines while maneuvering at low altitude.

NTSB analysis

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.
