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 ROLLED OVER AS IT WAS LIFTING OFF FROM A TRANSPORT TRAILER. A POST-CRASH EXAM REVEALED THAT THE LEFT REAR TIE-DOWN STRAP ON THE TRAILER WAS WRAPPED AROUND ONE OF THE HELICOPTER SKIDS. THE GROUND CREWMAN BELIEVED HE HAD REMOVED ALL OF THE STRAPS PRIOR TO THE ATTEMPTED TAKEOFF. THE PLT STATED HE HAD VISUALLY CHECKED ALL TIE-DOWN STRAPS DURING HIS PREFLT. HOWEVER, THERE WAS EVIDENCE THE LEFT REAR TIE-DOWN STRAP (WHICH WAS ATTACHED TO THE TRAILER) HAD NOT BEEN UNHOOKED PROPERLY. THE PLT ACKNOWLEDGED THAT A HANDS-ON INSPN OF THE STRAP MAY HAVE PREVENTED THE OCCURRENCE.
