The helicopter was being used by a power transmission company to check pylons for sabotage. In a six-foot hover near a pylon, the helicopter began shaking violently and the pilot lost control. During the subsequent revolutions the main rotor struck and severed a domestic feeder line, which was not part of the network being inspected. The helicopter landed on its side and was destroyed. One tail rotor blade had failed in the area of the doubler, and the blade portion was flung some distance from the hover point. The blade was found to have sustained leading edge damage from an unknown object. The object was probably small, hard and spherical, possibly a steel ball bearing, travelling at a significant speed. The failure originated from this damage.
