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.
Probable Cause: the pilot's inadequate visual lookout, resulting in an inflight collision with powerlines. Contributing factors were the fog and the powerlines.
