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.

WARNINGS PLACED ON ALLEREST STATE THAT THE MEDICATION 'MAY CAUSE DROWSINESS; ALCOHOL, SEDATIVES, AND TRANQUILIZERS MAY INCREASE THE DROWSINESS EFFECT...USE CAUTION WHEN DRIVING A MOTOR VEHICLE OR OPERATING MACHINERY.'
