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 PILOT SAID THE AIRCRAFT WAS IN CRUISE FLIGHT WHEN THE ENGINE BEGAN TO GRADUALLY LOSE POWER, THEN QUIT ALTOGETHER. HE ATTEMPTED A FORCED LANDING IN A PASTURE, HIT A BERM DURING THE LANDING ROLL OUT AND THE AIRCRAFT NOSED OVER. FAA INSPECTORS EXAMINED THE AIRCRAFT AND FOUND FUEL IN ALL TANKS AND LINES. THE ENGINE WAS STARTED IN THE AIRCRAFT AND EXERCISED THROUGHOUT ITS NORMAL POWER RANGE. THE ARCATA AVIATION SURFACE OBSERVATION WAS REPORTING A TEMPERATURE OF 50 DEGREES AND A DEW POINT OF 38 DEGREES. REVIEW OF THE CARBURETOR ICING PROBABILITY CHART REVEALED THAT THE TEMPERATURE AND DEW POINT WAS LOCATED IN AN AREA OF THE CHART DEFINED AS 'SERIOUS ICING, CLIMB OR CRUISE POWER.'
