Probable cause

The pilot did not maintain clearance from wires during an aerial application flight.

NTSB narrative

The pilot reported that while performing an aerial application flight at low altitude, the helicopter impacted wires between two poles. He stated the wires were higher than he expected due to the change in terrain contours relative to the poles, and he did not see the wires until just before impact. He then performed a precautionary landing to an adjacent waterway. The helicopter sustained substantial damage to the main rotor blades. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
