Aircraft Accident/Incident Report
Eagle Pass, Texas 78852
Tuesady, October 7, 2003 11:58 CDT
NTSB Narrative Summary Released at Completion of Accident
The 2,363-hour pilot reported that he was maneuvering the helicopter at an altitude of 30 to 60 feet AGL, with 5 to 10 knots forward airspeed when the nose of the helicopter started to move to the right. The pilot corrected for this with the left pedal. The nose of the helicopter stopped momentarily then started moving back to the right and could not be stopped with full left pedal. The helicopter was spinning uncontrollably to the right and the engine and rotor RPM increased. The pilot tried to hold the helicopter level with the cyclic, lowered the collective, held full left pedal and started to retard the throttle when contact with the ground occurred. The helicopter came to rest on its left side. The pilot reported that the tail rotor was not turning when the helicopter hit the ground. Examination of the helicopter by the operator revealed that the aft segment of the tail rotor drive shaft, approximately 24 inches forward of the tail rotor gear box attach point, was separated. The reason for the separation was not determined.
NTSB Probable Cause Narrative
The failure of the aft segment of the tail rotor drive shaft for undertermined reasons. A contibuting factor was the lack of suitable terrain for the foced landing.
