The pilot was hovering to parking when the helicopter experienced a failure of the tail rotor drive shaft. The pilot attempted a hovering autorotation, hovering he did not apply collective pitch. The helicopter collided with the ground in a right skid low condition and rolled over on its right side. Examination of the tailrotor drive shaft revealed excessive wear on the splines to the upper U-joint and on the splines of the transmission output shaft.
Probable Cause: The disconnection of the tail rotor drive shaft and subsequent lack of tail rotor control. Contributing factors were the worn drive shaft splines and the pilots' failure to apply collective on the touchdown resulting in a hard landing and subsequent roll over.
