Aircraft Accident/Incident Report

Wahiawa, Hawaii 96786
Wednesday, December 17, 2003 16:30 HST

NTSB Narrative Summary Released at Completion of Accident

The commercial helicopter pilot was transporting a sling load of ladders taped together and suspended by a 15-foot line. During the flight, the load shifted, and a ladder struck the tail rotor. The tail rotor separated from the helicopter, and the pilot initiated an emergency autorotation. The helicopter landed at an off-airport site and rolled onto its side. According to the operator's FAA-approved flight manual for external loads, the pilot has the sole responsibility to ensure that the load is properly rigged.

NTSB Probable Cause Narrative

The pilot's failure to properly secure the external sling load, which allowed the load to shift, and subsequently strike and remove the tail rotor.
