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 INTENTIONAL VFR FLIGHT INTO INSTRUMENT METEOROLOGICAL CONDITIONS, AND HIS FAILURE TO MAINTAIN ADEQUATE TERRAIN CLEARANCE. CONTRIBUTING FACTORS TO THE ACCIDENT WERE: THE PILOT'S FAILURE TO OBTAIN WEATHER INFORMATION, HIS OVERCONFIDENCE IN HIS ABILITY TO FLY IN MOUNTAINOUS TERRAIN IN THE EXISTING WEATHER CONDITIONS, THE URGENCY TO RETURN FOR OTHER PLANNED ACTIVITIES, THE EXISTING WEATHER CONDITIONS, AND THE MOUNTAINOUS TERRAIN CONDITION.
