Aircraft Accident/Incident Report

Stoneyford, California 95979
Thursday, June 17, 1993 11:30 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot said that he had established a hover in a mountain landing zone and was in the process of air taxiing to a point where the cargo could be unloaded. The pilot said that a gust of wind buffeted the helicopter and the tail rotor contacted a rise in the ground. The pilot said he then lost all yaw directional control and the helicopter settled hard into a creek, resulting in a buckle to the boom and damage to the internal skid attach structure.

NTSB Probable Cause Narrative

the pilot's inadequate compensation for the existing wind conditions during a hover operation. A factor in the accident was the high density altitude and the gusting, variable wind conditions.
