Aircraft Accident/Incident Report

Minden, Nevada 89423
Tuesady, September 9, 1997 15:35 PDT

NTSB Narrative Summary Released at Completion of Accident

The helicopter landed hard and a main rotor blade separated and struck a parked airplane. At the time of the accident the winds were 190 to 250 degrees at 15 knots, gusting to 23 knots. As the pilot continued his approach to the landing pad in a northeasterly direction, the helicopter yawed to the right and the pilot applied full left pedal and pulled collective. The pilot stated that the engine was running fine, and he had experienced 'no unusual noise,' and that he had 'run out of tail rotor.' Review of a relative wind chart shows the helicopter's heading during the approach to the pad placed it in an area of the chart where unanticipated right yaw might occur.

NTSB Probable Cause Narrative

A hard landing due to the failure of the pilot to adequately compensate for the wind direction and velocity on initiating his approach to the landing area, resulting in a loss of tail rotor authority.
