The NTSB's narrative final · quoted from the NTSB record
While attempting to turn some horses, the pilot applied excessive aft cyclic control and the tail rotor struck a large sage brush. Directional control was lost and the helicopter turned right. The pilot attempted a 'hovering autorotation' from 15 feet and a hard landing ensued. The main rotor blades struck and severed the tail boom, and the right skid collapsed.
