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 FLT WAS DESCENDING THRU 13000 FT WHEN TURBULENCE WAS ENCOUNTERED. FOUR PASSENGERS AND TWO FLIGHT ATTENDENTS WERE INJURED. THE PASSENGERS WERE INJURED WHEN THEIR SEATBELTS' END FITTINGS DETACHED FROM THEIR SEATS' TIE-DOWN SHACKLES AND THE PASSENGERS STRUCK CABIN FURNISHINGS. TESTS DETERMINED THAT WHEN A SHACKLE'S ATTACHMENT BOLT WAS OVERTIGHTENED (AND THE SHACKLE WAS NOT FREE TO SELF-CENTER) A SEATBELT LOAD WOULD BEND THE KEEPER ON THE BELT'S END FITTING AND THE FITTING WOULD OPEN AND DETACH FROM THE SHACKLE.
