The NTSB's narrative final · quoted from the NTSB record
The helicopter came out of maintenance, the captain and first officer conducted a test flight, and then ferried it to the area of operation. The next day, the captain entered a 155-foot out of ground effect hover, and an external load was connected. About the same time, the helicopter started a slow uncommanded yaw to the right. The captain applied full left pedal, released the load, and entered an autorotation. Examination of the tailrotor control system revealed that the left anti-torque control cable was broken. The break was associated with a pulley assembly, the cable strands were bent rearward, and deformed. The cable fracture surfaces were irregular, and also deformed. The associated keeper pins displayed wear marks, and light scratches consistent with control cable contact. The associated pulley was intact. The pulley channel contained an oil-based debris, and control cable fragments. Both tailrotor cables were removed and reinstalled within the last 5.3 hours of operation by company maintenance personnel.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number NYC03LA037.
