NTSB Narrative Summary Released at Completion of Accident

During a maintenance test flight, the pilot reported that while performing blade tracking procedures, a rotor droop was noticed followed by engine rpm decay. The pilot tried to increase engine power, however, the engine did not respond. During the autorotation, beginning at about 450 feet AGL, the helicopter landed hard. The main rotors subsequently contacted and severed the tail boom. Inspection of the engine revealed that the fuel nozzle filter was found to be completely covered with a dark green/brown colored substance and was collapsed. The fuel filter bowl was removed and a volume of water was present in the fuel that was drained from the filter bowl. Samples were taken and analyzed. The analysis "strongly indicated water contamination and possible fungal or bacteria growth in the fuel supply." The pilot reported that the fuel supplier and mobile pick-up truck all had filtering devices. The helicopter was not equipped with an external airframe mounted filter.

NTSB Probable Cause Narrative

Fuel starvation as a result of a collapsed fuel nozzle filter screen. Contamination that blocked the fuel nozzle screen and water contamination were factors.
