Aircraft Accident/Incident Report

Jacksonville, Florida 32244
Wednesday, July 25, 2001 18:40 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot stated that he started a descent into the area heading east into the wind, and down to 300 feet. He said he made several passes, and on the last pass he made a left turn, and had started turning to the right when the aircraft developed a fast yaw to the right, indicative of imminent loss of tail rotor effectiveness (LTE). The pilot said he immediately reduced collective and nosed the aircraft forward, and started losing altitude fast with no significant improvement in the yaw rate to the right. He said he pulled power to arrest the descent rate, and the yaw rate got faster, and he made a forced landing between two houses, pulling power at the bottom to arrest the descent rate. During the forced landing, the right skid touched down on the side of the roof, the aircraft then rolled left and came down to the ground. The pilot said that prior to the accident, there had been no mechanical failure or malfunction to the aircraft, or to any of its systems.

NTSB Probable Cause Narrative

the pilot's failure to recognize and correct for unanticipated right yaw/loss of tail rotor effectiveness (LTE) during an approach to hover at a low altitude, which resulted in a loss of control and the helicopter descending and colliding with a house and the ground.
