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
ENGINE FAILURE DUE TO TOTAL OIL LOSS. CONTRIBUTING TO THE ACCIDENT WERE THE SEPARATION OF THE OIL FILTER ADAPTER FROM THE OIL PUMP DUE TO IMPROPER MAINTENANCE PROCEDURES AND NON ADHERENCE TO RECOMMENDED DIRECTIVES BY COMPANY MAINTENANCE PERSONNEL, AND THE UNSUITABLE TERRAIN ON WHICH TO MAKE THE FORCED LANDING.
