The helicopter landed hard following a loss of engine power during cruise flight. The pilot was en route to refuel his single-engine turbo-shaft powered helicopter. The pilot stated in the Pilot/Operator Accident/Incident Report (NTSB form 6120.1) that the aircraft was in cruise flight at an indicated airspeed of 115 knots while at 500 feet above ground level when the engine lost power without warning. The pilot added that following the loss of engine power, he immediately entered autorotation and landed on a logging road surrounded by tall trees. The aircraft sustained structural damage to the tailboom and main rotor blades during the forced landing. The helicopter came to rest in the upright position. A detailed investigation was conducted on the fuel system by a Federal Aviation Administration inspector and a representative from the helicopter manufacturer. Their investigation revealed that a fuel transfer check valve located in the aft section of the fuel tank that receives fuel from the forward section of the fuel tank, was found stuck in the closed position, which resulted in fuel starvation to the engine.
Probable Cause: The loss of engine power due to fuel starvation as result of a fuel transfer check valve stuck in the closed position. A contributing factor was the lack of suitable terrain for the forced landing.
