Final Report from TSB: The pilot was conducting a positioning flight from Key Pile Camp, British Columbia, to the airstrip at Helmut, a distance of 10 kilometres. The pilot descended on approach over surrounding trees while headed in an easterly direction toward the west side of the threshold of runway 31.
The pilot had been in radio communication with a helicopter operating in the immediate area and did not indicate any emergency situation. The helicopter descended rapidly in a nose-low, right-banked turn. The approach path was cluttered with temporary buildings, vehicles, and water-filled dugouts. The lower vertical fin of the helicopter struck a steel pipe fence located on the west side of the threshold of runway 31. The fuselage contacted the threshold surface in a nose-down, right-side-low attitude, breaking off the skid gear and cross tubes.
The helicopter swung around in a clockwise direction, came to rest on a magnetic heading of 213 degrees, and was consumed by fire. The pilot did not escape from the wreckage and succumbed to the fire. The occurrence happened at about 0755 Pacific daylight time, in daylight conditions.
Findings as to Causes and Contributing Factors
1. A screw on the engine fuel control unit failed, resulting in fuel leakage and a decrease in engine power below that required to sustain flight.
2. The screw did not conform to the manufacturer=s drawing or heat treatment specifications and failed because of hydrogen embrittlement cracking.
3. While the pilot attempted to autorotate the helicopter to a suitable landing area, the main-rotor rpm decayed, and the helicopter struck a steel pipe fence.
