Probable cause

The pilot’s failure to maintain clearance from power lines during a low-level aerial application flight.

NTSB narrative

The pilot reported that while making a turn at the end of a field following an aerial application pass, the helicopter struck power lines and subsequently impacted the ground. The helicopter sustained substantial damage to the fuselage and main rotor system. The pilot did not report any preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operations. The pilot reported he was aware of the power lines but misjudged the position of the helicopter with reference to the lines and realized that he did not have sufficient room to make the turn without impacting the lines. The pilot stopped the turn and lowered the collective to attempt to pass under the power lines. The helicopter impacted the lower string of lines and impacted the ground, coming to rest almost upright.
