The directive was issued after discovering the original brackets were prone to cracking at specific stress points.\n\n**What must be done:**\n- **Inspection:** Check the left-hand and right-hand hinge brackets (part numbers 60-524078-3 and 60-524078-4) for cracks, especially at the ends of the vertical leg and forward ends of the angled legs. This must happen every 50 flight hours until the parts are replaced.\n- **Replacement:** Install improved brackets (following Beechcraft Service Instruction 0342-132, Revision IV) within 200 flight hours after 20 May 1975.\n\n**Who it affects:**\nAnyone operating or maintaining the specified Beechcraft 60 and 60A aircraft — typically private owners, charter operators, or flying schools using these twin-engine piston aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-60-22-amdt-1-elevator-hinge-bracket","history":"/api/acts/ad-beech-60-22-amdt-1-elevator-hinge-bracket/history","analysis":"/api/acts/ad-beech-60-22-amdt-1-elevator-hinge-bracket/analysis","conflicts":"/api/acts/ad-beech-60-22-amdt-1-elevator-hinge-bracket/conflicts","importantCases":"/api/acts/ad-beech-60-22-amdt-1-elevator-hinge-bracket/important-cases","documents":"/api/acts/ad-beech-60-22-amdt-1-elevator-hinge-bracket/documents"}}
