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.

BOTH PILOTS REPORTED THAT THEY ENCOUNTERED A DOWNDRAFT DURING THE FINAL APPROACH WHICH CAUSED THE AIRPLANE TO DEVELOP A HIGHER THAN DESIRED SINK RATE. THE APPLICATION OF POWER FAILED TO ARREST THE SINK RATE BEFORE THE AIRPLANE TOUCHED DOWN APPROXIMATELY ONE FOOT SHORT OF THE RUNWAY. THE AIRPLANE CAME TO A STOP ABOUT 1,000 FEET DOWN THE RUNWAY, WITH ALL THREE LANDING GEAR COLLAPSED. THE PILOT SAID THAT HE HAD ENCOUNTERED LIGHT TO MODERATE TURBULENCE DURING THE APPROACH, AND HE WAS 'SHOOTING FOR THE END OF THE RUNWAY'.
NTSB Probable Cause
THE PILOT'S IMPROPER INFLIGHT PLANNING/PREPARATION, AND HIS FAILURE TO ATTAIN THE PROPER TOUCHDOWN POINT. CONTRIBUTING TO THE ACCIDENT WAS THE DOWNDRAFT.
