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 HEARDING CATTLE WITH THE HELICOPTER WHEN THE ACCIDENT OCCURRED. HE WAS TRAVELING SLOW AND PARALLEL WITH A BARBED WIRE FENCE. HE HAD TO TURN TO THE RIGHT TO AVOID A TREE WHICH WAS DIRECTLY AHEAD OF THE ACFT. UPON MAKING THE TURN HE CAUGHT THE TAIL ROTOR IN THE FENCE AND TORE THE TAIL ROTOR ASSEMBLY OFF THE TAIL BOOM. THE HELICOPTER THEN WENT INTO A SPIN. THE PLT CLOSED THE THROTTLE AND LANDED THE HELICOPTER. THE TOUCHDOWN WAS HARD ENOUGH THAT THE FUSELAGE WAS SLIGHTLY WARPED DURING THE IMPACT.
