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.

POST-ACCIDENT EXAMINATION REVEALED NO EVIDENCE OF PRE-IMPACT MECHANICAL MALFUNCTION. WEATHER CONDITIONS WERE CONDUCIVE TO SERIOUS INDUCTION SYSTEM ICING AT CRUISE POWER SETTINGS.
NTSB Probable Cause
THE PILOT'S FAILURE TO SELECT CARBURETOR HEAT IN A TIMELY MANNER, AND THE TOTAL LOSS OF ENGINE POWER DUE TO CARBURETOR ICE. RELATED FACTORS ARE CARBURETOR ICING CONDITIONS, REDUCED VISIBILITIES IN SNOW, LOW CEILINGS, THE DARK NIGHT, AND SOFT TERRAIN CONDITIONS.
