NTSB Narrative Summary Released at Completion of Accident

The helicopter collided with power lines during an aerial application. The pilot was on his nineteenth pass over the field, traveling eastbound. Power lines were located on the east and west side of the road. There was a pole about 75 feet tall, and the top 6 feet contained three wires. The top wire, a black colored insulator wire, was located 3 feet from the top of the pole. The pilot located the outbox on the pole and determined he would fly above the box to clear all of the wires. As he flew over the lines, the helicopter impacted the insulator wire about 1/2 foot above the cockpit floor. The helicopter slid along the wire and then the wire broke from the insulator at the next pole. The poles were placed about 300 feet apart. As the helicopter impacted the ground, the left skid hit first, followed by the main rotor.

NTSB Probable Cause Narrative

the pilot's failure to maintain clearance with the wires due to an inadequate visual lookout.
