Sunday, August 12, 2001 14:30 MDT
NTSB Narrative Summary Released at Completion of Accident
The pilot was performing an off-site landing with a long-line. The line became entangled in brush, and subsequenmtly, the line became entangled in the tail rotor drive shaft. The tail rotor drive shaft failed, and the pilot performed an autorotation impacting equipment on the ground. During the landing sequence, the tail boom and horizontal stabilizer were bent, and the bottom of the helicopter's fuselage was penetrated.
NTSB Probable Cause Narrative
the pilot's inadequate in-flight planning for an off site landing, which resulted in failure of the tail rotor drive shaft due to entanglement of his long-line in the drive shaft.
