NTSB Narrative Summary Released at Completion of Accident
The helicopter had been contracted by the State to relocate moose to an area where they would be less hazardous to traffic. After the helicopter herded a moose off a frozen reservoir and back towards the shoreline, the pilot turned and flew into five power lines. The helicopter nosed over, and fell 80 feet in a near-inverted attitude to the surface of the frozen reservoir. It broke through the ice, sank, and then floated back to the surface. A portion of the tail boom remained entangled in the wires. Witnesses said the visibility was 1 mile in fog. An examination of the wreckage revealed no anomalies.
NTSB Probable Cause Narrative
the pilot's inadequate visual lookout, resulting in an inflight collision with powerlines. Contributing factors were the fog and the powerlines.
