The Bell 206B helicopter was being utilized to sling barrels of fuel at a remote tent camp. As the pilot was about to place two barrels near the camp generator shed, he lost tail rotor authority. The helicopter rotated rapidly to the right through approximately three revolutions, struck the ground upright, and rolled onto the right side. The pilot received minor injuries and the helicopter was substantially damaged.
The Board determined that the aft short tail rotor drive shaft failed in an area weakened by intergranular cracking which initiated from corrosive attack on the interior wall of the shaft. The drive shaft failure resulted in a loss of tail rotor thrust. The failure occurred when the helicopter was hovering at an altitude which precluded a successful autorotation.
