Archer City, TX, USA
N2875F
BELL-TRANSWORLD HELICOPTERS 47D1
The private pilot reported that he departed from his ranch and was flying about 100 ft above ground level and at 50 knots. He intended to position the carburetor heat to "on," but he inadvertently positioned the mixture control to the "fuel cutoff" position instead, and the engine lost total power. He immediately entered an autorotation, but because the helicopter was so low and slow, there was insufficient time and altitude to flare the helicopter. He stated that the airspeed decreased and that the main rotor blade stalled, which caused the helicopter to just "drop." The pilot reported no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation. The pilot's inadvertent positioning of the mixture control to the "fuel cutoff" position resulted in fuel starvation and the total loss of engine power.
