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.

WHEN THE PLT EXTENDED THE GEAR, THE LANDING GEAR MOTOR CIRCUIT BREAKER (C/B) POPPED. HE RESET THE C/B & AFTER A COOL DOWN PERIOD ATTEMPTED TO EXTEND THE GEAR AGAIN, BUT WITH THE SAME RESULTS. THE PLT WAS NOT ABLE TO EXTEND THE GEAR FULLY DOWN & LOCKED WITH THE EMERGENCY EXTENSION SYSTEM. THE ACFT WAS SUBSEQUENTLY LANDED WITH THE LANDING GEAR PARTIALLY EXTENDED & THE GEAR COLLAPSED. EXAM REVEALED THAT SEVERAL P/N 5201KD BEARINGS WERE BROKEN & HAD BECOME JAMMED BETWEEN THE WORM GEAR & THE GEAR BOX HOUSING OF THE LANDING GEAR ACTUATING SYSTEM. THERE WAS LITTLE GEAR LUBRICANT IN THE ACTUATOR. THE ACTUATOR HAD BEEN OPERATED 4,538 HRS SINCE NEW & HAD NOT BEEN OVERHAULED. THE MANUFACTURER'S RECOMMENDED OVERHAUL PERIOD IS 2,000 HRS.
