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 STUDENT'S FAILURE TO MAINTAIN A PROPER ALTITUDE AND CLEARANCE FROM THE TERRAIN ALONG WITH THE CFI'S FAILURE TO ADEQUATELY SUPERVISE THE STUDENT'S ACTIONS. A FACTOR CONTRIBUTING TO THE ACCIDENT WAS THE INADEQUATE VISUAL LOOKOUT AVAILABLE DUE TO THE NIGHT LIGHT CONDITIONS.
