Analysis

The pilot stated that the fuel gauge indicated 150 lbs of fuel remaining when he began the flight. Since the drop point was within 2 to 3 minutes of the departure point, he elected to proceed without refueling. While hovering and being guided into the drop point, the low fuel warning light flickered. The pilot completed the drop, and while returning to the refueling area, the light flickered 3 more times. The pilot stated that when he arrived at the refueling area, the fuel gauge indicated approximately 50 to 60 lbs of fuel remaining. Shortly after that, the engine lost power while the helicopter was still about 50 to 60 ft AGL. During an autorotation, the helicopter was landed on the hillside of a logging area while avoiding a truck.
