The commercial pilot reported that, while relocating the helicopter to a staging area to refuel, the engine experienced a total loss of power. He initiated an autorotation to a partially-wooded area, where the helicopter touched down and rolled onto its right side. The pilot stated that, before the loss of engine power, he noticed that the fuel quantity indication was not decreasing as he would have expected. Postaccident examination revealed that the fuel quantity gauge indicated more fuel in the fuel tank than the amount that was physically present. This erroneous fuel level indication led the pilot to believe that more fuel was available than what was in the fuel tanks, and subsequently resulted in a total loss of engine power due to fuel exhaustion.
Probable Cause: A total loss of engine power during cruise flight due to fuel exhaustion. Contributing to the accident was the improper calibration of the fuel quantity gauge.
