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.

DURING FLT BEFORE ACCIDENT FLT, THE LANDING GEAR MALFUNCTIONED. EMERGENCY GEAR EXTENSION WAS ACCOMPLISHED BUT REQUIRED EXCESSIVE FORCE. MAINTENANCE PERSONNEL LUBRICATED THE NOSE GEAR RETRACT CHAIN & ADJUSTED THE GEAR DOWN LIGHT INDICATOR SWITCH. THE AIRPLANE WAS FLOWN WITH NO DISCREPANCIES NOTED. THE ACCIDENT FLT WAS UNEVENTFUL UNTIL AFTER LOWERING THE LANDING GEAR SELECTOR HANDLE, THE GEAR DID NOT FULLY EXTEND. THE EMERGENCY METHOD WAS UNSUCCESSFUL. THE MAIN GEAR COLLAPSED DURING THE LANDING ROLL. EXAM OF THE LANDING GEAR SYSTEM REVEALED THAT THE NOSE GEAR ACTUATOR WAS SEIZED DUE TO LACK OF LUBRICATION. THE ACFT LOGBOOKS INDICATE THAT ALL GEAR ACTUATORS WERE REPLACED ON 8-23-86. THERE WERE NO FURTHER ENTRIES INDICATING THAT THEY WERE LUBRICATED. ACCORDING TO THE MAINT MANUAL, THE ACTUATORS SHOULD BE REMOVED FOR LUBRICATION EVERY 1,000 CYCLES OF OPERATION OR 30 MOS., WHICHEVER OCCURS FIRST. THE ACFT ACCUMULATED 3,154 CYCLES SINCE REPLACEMENT OF THE ACTUATORS.
