Probable cause

The pilot's failure to maintain control of the helicopter after a loss of engine power. The reason for the loss of engine power could not be determined because examination did not reveal any anomalies that would have precluded operation.

NTSB narrative

The commercial pilot and his passenger were conducting a low-level aerial photography operation in a helicopter when the engine stopped producing power. Several witnesses observed the helicopter descend vertically to the ground as the body of the helicopter spun to the left around the main rotor blades. A postimpact fire consumed most of the helicopter. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. Although the weather conditions at the time of the accident were conducive to the formation of carburetor icing at cruise and glide power settings, the investigation could not conclusively determine that carburetor ice caused the loss of engine power. The cause of the power loss could not be determined.
