Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

THE HELICOPTER WAS BEING USED ON AN EXTERNAL LOAD OPERATION TO MOVE EQUIPMENT FROM THE SIDE OF A MOUNTAIN. A 100 FT CABLE WAS STILL ATTACHED TO THE HELICOPTER WHEN WORKERS NEEDED TO BE TRANSPORTED UP THE HILL. WITNESSES REPORTED THE PILOT INITIATED A NORMAL TAKEOFF, INSTEAD OF A VERTICAL TAKEOFF, WHICH HE HAD BEEN USING WITH THE CABLE ATTACHED. DURING THE TAKEOFF, THE HOOK ON THE END OF THE CABLE SNAGGED ON AN EQUIPMENT TRAILER. THE HOOK BROKE FREE OF THE TRAILER AND THE CABLE REBOUNDED INTO THE MAIN ROTOR BLADES. THE HELICOPTER THEN BECAME UNCONTROLLABLE AND CRASHED.
NTSB Probable Cause
FAILURE OF THE PILOT TO MAKE A VERTICAL TAKEOFF, WHILE DEPARTING WITH A CABLE ATTACHED, AND HIS FAILURE TO INSURE THE CABLE REMAINED CLEAR OF THE TRAILER. THE TRAILER (VEHICLE) WAS A CONTRIBUTING FACTOR.
