NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
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.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: 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.
