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
THE PILOT'S INADEQUATE PREFLIGHT INSPECTION OF THE AIRCRAFT AFTER REFUELING. THE FAILURE OF THE AIRCRAFT MANUFACTURER TO PUBLISH THE REFUELING INSTRUCTIONS IN THE OPERATOR'S MANUAL, THE INADEQUATE FUEL SERVICING OF THE AIRCRAFT BY OTHER MAINTENANCE PERSONNEL AND THE FAILURE OF BOTH ENGINES FROM FUEL EXHAUSTION WERE FACTORS IN THE ACCIDENT.
