Aircraft Accident/Incident Report

Allen, Texas 75002
Sunday, July 16, 2000 1:40 CDT

NTSB Narrative Summary Released at Completion of Accident

The commercial helicopter pilot terminated the night approach to a 6 to 8-foot hover, with 'trees and 2 post-box's to the right and a large ditch to the left.' The pilot hovered the helicopter sideways to the left to move away from the trees. He then started a left pedal turn to face EMS units located behind the helicopter. He had turned the helicopter approximately 120 degrees, 'when I moved backwards' and struck the trees with the tail rotor. He immediately stopped the turn and moved the helicopter forward before losing tail rotor control. As the helicopter began to spin, he 'lowered the collective and landed hard.' The tail rotor drive shaft forward of the 45 degree gearbox was sheared.

NTSB Probable Cause Narrative

the pilot's failure to maintain obstacle clearance while hovering the helicopter. A contributing factor was the dark night light conditions.
