Aircraft Accident/Incident Report

Chiefland, Florida 32626
Friday, March 1, 1996 15:15 EST

NTSB Narrative Summary Released at Completion of Accident

The pilot stated that during cruise flight about 400 feet mean sea level he heard the engine decelerate then heard the engine-out audio. He maneuvered the helicopter for an autorotative landing in a clearing, but after observing uneven terrain he elected to zero his forward airspeed. After a hard landing the helicopter rocked forward causing the main rotor blades to contact the tailboom. Fuel quantity was sufficient to sustain engine operation and visually no contaminants were noted. The helicopter was recovered and the engine was started several times using the fuel supply in the fuel tank with no discrepancies noted. The engine was removed from the helicopter and tested at the manufacturers facility with no discrepancies noted. The power turbine governor (PTG) and the main fuel control and engine driven fuel pump were removed for bench testing. The only discrepancy noted was a failed roll pin for the throttle level stop in the PTG. The PTG manufacturer states that the failed roll pin would not effect operation of the unit.

NTSB Probable Cause Narrative

Improper cyclic and collective input by the pilot-in-command resulting in the hard landing during the autorotative landing. Contributing to the accident was the total loss of engine power due to undetermined reasons.
