The NTSB's narrative final · quoted from the NTSB record
The pilot was using the helicopter to herd cattle and was attempting to move a bull towards a corral when the animal charged the helicopter. As the pilot maneuvered to avoid the bull, the helicopter's tail rotor contacted the water in a stock tank (pond), resulting in failure of the tail rotor drive shaft. The pilot performed an autorotation. The helicopter spun twice to the right, touched down in a level attitude in the stock tank, and rolled onto its right side.
