The NTSB's narrative final · quoted from the NTSB record
The engine of the helicopter lost power after about 3 hours of flying. An autorotative descent was made to a site at 6,500 feet density altitude, and the helicopter was damaged during the landing. After the accident, 1.9 gallons of fuel were drained from the entire fuel system. The helicopter's unusable fuel quantity was 2.5 gallons. Examination of the helicopter revealed no evidence of a preaccident mechanical malfunction or failure. A manufacturer's representative opined that an autorotative landing at 6,500 feet density altitude would likely result in a hard landing. The engine carburetor flow tested within the manufacturer's specifications.
