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.

DURING A SOLO INSTRUCTIONAL FLIGHT, THE PILOT ALLOWED THE GLIDER TO GET LOW ON FINAL APPROACH. UNABLE TO REACH THE AIRPORT, HE LANDED THE GLIDER SHORT OF THE RUNWAY. DURING THE LANDING ROLL, IT COLLIDED WITH THE AIRPORT BOUNDARY FENCE.

NTSB Probable Cause

THE PILOT MISJUDGED HIS DISTANCE AND ALTITUDE TO THE RUNWAY DURING THE APPROACH AND FAILED TO ATTAIN THE PROPER TOUCHDOWN POINT FOR LANDING. HIS LACK OF EXPERIENCE IN THE MAKE AND MODEL OF GLIDER WAS A RELATED FACTOR.
