Flight Details
The helicopter had just departed from runway 05. According to ground witnesses and several occupants on board, when the helicopter reached approximately 150 feet above ground level (AGL), it experienced a total loss of engine power.
Accident Sequence
The pilot immediately initiated an autorotation, performing an abrupt right turn. The airport is situated on a plateau, and the surrounding terrain slopes downward from the runway. The helicopter subsequently crashed about 100 yards east of the departure end of the runway.
Post-Impact Examination
Examination of the engine after the accident revealed that it was not operating at the time of impact. However, when the engine was tested during the investigation, it operated normally. The airframe fuel filter was found to contain discolored fuel and some contaminants. Notably, the fuel downstream of the filter was free of any discoloration or contaminants.
