NTSB Narrative Summary Released at Completion of Accident

While hovering the helicopter during the installation of a transmission wire about 70 feet above the ground, the pilot inadvertently allowed the left horizontal stabilizer to move laterally until it was beneath the wire. When the pilot attempted to climb the helicopter away from the wire, the wire hooked the stabilizer. The helicopter subsequently pitched forward and the main rotor blades and rotor mast also became entangled with the wire. The main rotor blades and tail boom then broke away from the helicopter, which spun once or twice before hitting the ground. There were no mechanical anomalies noted with the helicopter and no appreciable wind.

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance from the overhead wire.
