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 PILOT REPORTED THAT APPROACHING THE DESTINATION AIRPORT HE EXTENDED THE WING FLAPS, LOWERED THE LANDING GEAR AND OBSERVED THREE GREEN GEAR LIGHTS. THE AIRPLANE 'FLOATED' OVER THE 3640-FOOT LONG RUNWAY AND INITIALLY TOUCHED DOWN 800 TO 900 FEET BEYOND THE THRESHOLD. THEREAFTER, THE RIGHT MAIN LANDING GEAR PARTIALLY RETRACTED, THE WING CONTACTED THE RUNWAY'S SURFACE AND THE AIRPLANE VEERED INTO A DITCH. DURING THE EXAMINATION OF THE WRECKAGE, THE WING FLAPS WERE FOUND IN THE RETRACTED POSITION AND THE LANDING GEAR SYSTEM FUNCTIONED NORMALLY. THE PHYSICAL EVIDENCE INDICATED THAT DURING ROLLOUT THE LANDING GEAR MOTOR WAS ACTIVATED WHILE SOME WEIGHT WAS ON THE LEFT MAIN GEAR. THIS RESULTED IN A BENDING OF THE LEFT GEAR ACTUATOR ARM AND THE PARTIAL RETRACTION OF THE RIGHT GEAR. THE FLAPS WERE FOUND GROUND IMPACT DAMAGED AND RETRACTED.
NTSB Probable Cause
