The NTSB's narrative final · quoted from the NTSB record
THE PLT HEARD A LOUD 'SNAP' WHILE TAXIING TO THE RWY, AND THE LDG GEAR COLLAPSED IMMEDIATELY THEREAFTER. THE PLT OBSERVED THAT THE GEAR HANDLE WAS STILL IN THE DOWN-AND-LOCKED POSITION AND THAT THE GREEN 'GEAR DOWN' LIGHT REMAINED ILLUMINATED. FAA EXAM OF THE MANUALLY OPERATED LDG GEAR SYSTEM REVEALED THAT THE GEAR HANDLE/LEVER ASSY HAD CRACKED AND SEPARATED WHERE IT WAS WELDED TO A CROSS MEMBER. METALLURGICAL EXAM OF THE FRACTURE SURFACES REVEALED EVIDENCE OF BENDING OVERSTRESS SEPARATION. EXAM OF THE ACFT MAINTENANCE RECORDS REVEALED THAT THE LDG GEAR HAD BEEN RE-RIGGED ABOUT 11 FLT HRS BEFORE THE ACCIDENT OCCURRED. THE ACFT MAINTENANCE MANUAL NOTES THAT THE OVERCENTER CONFIGURATION OF THE RETRACTION LINKAGE HOLDS THE GEAR DOWN AND LOCKED, AND WARNS THAT IMPROPER GEAR RIGGING CAN RESULT IN A GEAR COLLAPSE DURING TAXIING OR LDG.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number ATL87LA247.
