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 PLT RPRTD THAT DRG TAKEOFF, THE ACFT REACHED AN ALTITUDE OF ABOUT 50 TO 75 FT, WHEN HE NOTICED THE AIRSPEED WAS SLOWLY DROPPING. HE DID NOT BELIEVE THE ACFT WOULD CLEAR TREES BEYOND THE END OF THE RWY, SO HE ELECTED TO ABORT THE TAKEOFF. SUBSEQUENTLY, THE ACFT TOUCHED DOWN, NOSEWHEEL FIRST, BETWEEN THE END OF THE RWY & THE TREES, THEN IT NOSED OVER. RPRTDLY, THE FLAPS WERE IN A FULL DOWN POSITION.
NTSB Probable Cause
IMPROPER PREFLIGHT PREPARATION BY THE PILOT BY TAKING OFF WITH THE FLAPS EXTENDED, WHICH RESULTED IN AN INADEQUATE RATE OF CLIMB TO CLEAR OBSTRUCTIONS BEYOND THE END OF THE RUNWAY, AND THE PILOT'S DELAY IN ABORTING THE TAKEOFF AND HIS FAILURE IN MAINTAINING AIRSPEED, WHICH REDUCED HIS ABILITY TO FLARE THE AIRCRAFT. THE HIGH OBSTRUCTIONS (TREES) NEAR THE END OF THE RUNWAY WERE CONSIDERED TO BE A FACTOR.
