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 OPERATOR SAID THE PILOT TOLD THEM HE WAS PRACTICING SLOW FLIGHT MANEUVERS AND THE ENGINE FALTERED WHEN HE ADDED POWER TO EXIT THE MANEUVER. THE PILOT FIRST DECIDED TO LAND ON A NEARBY GOLF COURSE, HOWEVER, HE OBSERVED MANY PEOPLE ON THE FAIRWAYS AND ELECTED TO LAND ON NEARBY BEACH. THE AIRCRAFT COLLIDED WITH ROCKS AND THE GROUND DURING THE LANDING FLARE. THE OFFICIAL SAIPAN WEATHER OBSERVATION FOR THE ACCIDENT TIME LISTS A TEMPERATURE OF 80 DEGREES AND A DEW POINT OF 74 DEGREES. EXAMINATION OF THE CARBURETOR ICING PROBABILITY CHART REVEALS THAT THE TEMPERATURE AND DEW POINT ARE IN AN AREA DEFINED AS 'SERIOUS ICING GLIDE POWER.'
