The pilot reported that he was flying the helicopter parallel to a 10-ft-tall fence while herding cows into a livestock pen. While maneuvering, the tail rotor struck the fence, and the helicopter spun multiple times. The helicopter ascended about 10 ft, and the pilot retarded the throttle and lowered the collective to the full-down position to minimize the rapid right spin. The helicopter impacted the ground and came to rest upright. The helicopter sustained substantial damage to the tail rotor drive system and tailboom.

Probable Cause: The pilot's failure to maintain clearance from a fence during low-altitude maneuvering.
