Aircraft Accident/Incident Report

Rangely, Colorado 81648
Tuesady, September 10, 1996 16:15 MDT

NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

the pilot's excessive cyclic control input during a low altitude operation, and his failure to maintain altitude/clearance from high vegetation (sage brush). The proximity of high vegetation was a related factor.
