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 CERTIFICATED PRIVATE PILOT, THE SOLE OCCUPANT, WAS LANDING AFTER CONDUCTING TOUCH AND GO TAKEOFFS AND LANDINGS. DURING THE FINAL LANDING APPROACH, THE PILOT FAILED TO ARREST THE EXCESSIVE SINK AND THE AIRPLANE TOUCHED DOWN ABOUT 12 INCHES SHORT OF THE PAVED END OF THE RUNWAY. THE PAVED RUNWAY WAS ABOUT 6 INCHES ABOVE THE SURROUNDING UNPAVED AREA. WHEN THE RIGHT LANDING GEAR STRUCK THE LIP OF THE RUNWAY, THE STRUT WAS BENT AFT ABOUT 20 DEGREES AND THE RIGHT WING RECEIVED STRUCTURAL DAMAGE. THE FAA ADVISORY CIRCULAR RECOMMENDS THAT THE RUNWAY LIP DISTANCE TO THE SURROUNDING RUNWAY SAFETY AREA IS 1 AND 1/2 INCHES FOR DRAINAGE, WITH A MAXIMUM RECOMMENDED DISTANCE OF 3 INCHES. THE AIRPORT PERSONNEL FAILED TO MAINTAIN THESE RECOMMENDED DISTANCES.
NTSB Probable Cause
THE FAILURE OF THE PILOT TO ARREST AN EXCESSIVE SINK RATE RESULTING IN NOT ATTAINING THE PROPER TOUCH DOWN POINT AND LANDING SHORT OF THE RUNWAY THRESHOLD. CONTRIBUTING TO THE ACCIDENT WAS AN EXCESSIVE RUNWAY END LIP DUE TO INADEQUATE RUNWAY END MAINTENANCE.
