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 PILOT WAS CONDUCTING A SLING LOAD OPERATION WITH A 50 FT CABLE ATTACHED. AFTER THE LAST SLING LOAD WAS MOVED TO A NEW DRILLING SITE, THE PILOT ELECTED TO LEAVE THE CABLE ATTACHED SINCE THERE WAS NO SUITABLE LANDING AREA NEARBY. HE STATED THAT THE CABLE WAS TRAILING NICELY AS HE DESCENDED DOWN A 1500 FT BLUFF ABOVE THE MAIN CAMP. HOWEVER, AS HE REDUCED THE RATE OF DESCENT AND FORWARD VELOCITY, AND APPLIED POWER, THE CABLE BECAME ENGAGED IN THE TAIL ROTOR. SUBSEQUENTLY, THE PILOT LOST EFFECTIVE CONTROL OF THE HELICOPTER AND CRASHED ON A ROCKY BEACH. THE TAIL ROTOR AND TAIL ROTOR GEAR BOX WERE FOUND ABOUT 100 FT FROM THE HELICOPTER.
