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.

NTSB Probable Cause
POOR JUDGEMENT OF THE NON-RATED PILOT, DUE TO IMPAIRMENT FROM CONSUMPTION OF ALCOHOL, HIS LACK OF TRAINING/QUALIFICATION, HIS IMPROPER USE OF THE ENGINE CONTROLS WHICH RESULTED IN LOSS OF ENGINE POWER FROM PROBABLE CARBURETOR ICE, AND HIS FAILURE TO MAINTAIN SUFFICIENT AIRSPEED WHICH RESULTED IN AN INADVERTENT STALL AND SUBSEQUENT COLLISION WITH THE TERRAIN.
