THIS CASE WAS MODIFIED DECEMBER 20, 2005.
The pilot was attempting to land in a strong quartering tailwind because his passenger had become air sick. He said the helicopter 'was practically in a hover [with] full power applied. . .when a gust of wind from behind hit me just as I was turning into the wind using left pedal. The helicopter weather vaned, I reacted with full right pedal and then the gust either stopped or came from a different direction weather vaning us back to the west where I applied full left pedal. I could feel buffeting in the controls similar to turbulence. The right yaw was so rapid that I entered loss of tail rotor effectiveness.' The helicopter collided with terrain while it was still turning and rolled over. According to the passenger, the pilot had attempted landings earlier in the day but had difficulty with the wind. He succeeded in landing after several attempts.
Probable Cause: Loss of tail rotor effectiveness. A factor was the quartering tailwind.
