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 PLT WAS SPRAYING A POTATOE FIELD WITH A LIGHTLY LOADED HELICOPTER WHEN THE ENG FAILED. AT THAT TIME, THE HELICOPTER WAS ABOUT 10 FT AGL IN A SLIGHT RIGHT TURN & AT APRX 35 MPH. THE PLT FLARED TO STOP THE FORWARD MOVEMENT & LANDED, BUT THE TAIL ROTOR SECTION CONTACTED THE GROUND & SEPARATED FROM THE TAIL BOOM. AN EXAM OF THE ENG REVEALED THAT THE #6 CONNECTION ROD HAD FAILED & PUNCTURED THE CRANKCASE.
