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 REPORTED THAT HE NOTED A FAIRLY LOUD SOUND AS THE LANDING GEAR LOCKED IN THE UP POSITION. LATER, HE WAS UNABLE TO EXTEND THE GEAR WITH EITHER THE NORMAL OR EMERGENCY SYSTEMS. THE CIRCUIT BREAKER WOULD POP EACH TIME HE TRIED THE NORMAL SYSTEM. THE EMERGENCY GEAR HANDCRANK WOULD NOT ENGAGE TO EXTEND THE GEAR MANUALLY. THE ACFT WAS LANDED WITH THE GEAR RETRACTED. AN INVESTIGATION REVEALED THAT A BUSHING, PN 35-810077-3, IN THE LANDING GEAR ACTUATOR HAD FAILED. THIS ALLOWED A WORM GEAR IN THE ACTUATOR TO MOVE AND JAM THE REDUCTION GEAR. THIS ALSO PREVENTED THE HANDCRANK FROM ENGAGING.
