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.

AFTER PASSING OVER THE MIDFIELD LOCATION A DOWNDRAFT WAS ENCOUNTERED AND THE AIRCRAFT'S AIRSPEED DECREASED FROM 80 TO 65 KNOTS. THE RUNWAY WAS 8544 FEET LONG, AND THE PILOT, BELIEVING THE AIRCRAFT WOULD LIKELY NOT OUTCLIMB THE HIGH TERRAIN SOUTH OF THE FIELD, DECIDED TO ABORT THE TAKEOFF. THE PILOT IMMEDIATELY APPLIED FULL FLAPS, LOWERED THE NOSE AND ATTEMPTED TO LAND ON THE REMAINING RUNWAY. THE AIRCRAFT OVERRAN THE END OF THE RUNWAY BY 100 YARDS AND COLLIDED WITH A BERM.
