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
IMPROPER IN-FLIGHT PLANNING/DECISION BY THE PILOT AND HIS FAILURE TO MAINTAIN ADEQUATE FLYING SPEED, WHICH RESULTED IN A STALL AND SUBSEQUENT IMPACT WITH THE TERRAIN. CONTRIBUTING FACTORS WERE: OPERATION OF THE AIRCRAFT BY THE PILOT WITH EXCESSIVE GROSS WEIGHT, HIS LACK OF EXPERIENCE IN THIS MAKE AND MODEL OF AIRCRAFT AND THE TERRAIN CONDITIONS.
