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.

THE INADEQUATE PREFLIGHT PLANNING AND PREPARATION BY THE STUDENT PILOT, THE STUDENT PILOT'S CONTINUED FLIGHT INTO KNOWN ADVERSE WEATHER AND THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL ON THE ROADWAY LANDING. FACTORS RELATING TO THE ACCIDENT WERE: THE WEATHER OBSCURATION, INADEQUATE STUDENT TRAINING IN CROSS COUNTRY PLANNING AND WEATHER AVOIDANCE BY THE INSTRUCTOR, THE TERRAIN (ROADWAY) SELECTED FOR FORCED LANDING, AND THE SNOWBANK BORDERING THE LANDING AREA.
