The concern is that these seat attachments could fail during an emergency landing, which would obviously be catastrophic if the pilots were thrown around or lost control.\n\n**Who it affects:**\n- Owners and operators of specific Beechcraft Model A36, A36TC, and B36TC aircraft with particular serial numbers (listed in the \"Applicability\" section)\n- Maintenance engineers who issue Maintenance Releases (the Australian equivalent of an airworthiness certificate for continued operation)\n\n**What must be done:**\n- For some aircraft: Follow Beechcraft Mandatory Service Bulletin 2010, Part I\n- For others: Follow both Part I and Part II of that same bulletin\n- Alternatively, compliance with Beechcraft Service Bulletin 2233 is also acceptable\n\n**When:**\nBy the next scheduled inspection when the Maintenance Release is due for renewal after 29 December 1988.\n\n**Why it matters:**\nThis is a **life-safety issue**. If the seat tracks fail in a crash landing, the pilots could be injured or unable to control the aircraft, endangering everyone on board. The directive ensures critical structural components are reinforced before they can fail."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-36-33-amdt-1-pilot-and-co-pilot-seat-tracks-and-seat-frames","history":"/api/acts/ad-beech-36-33-amdt-1-pilot-and-co-pilot-seat-tracks-and-seat-frames/history","analysis":"/api/acts/ad-beech-36-33-amdt-1-pilot-and-co-pilot-seat-tracks-and-seat-frames/analysis","conflicts":"/api/acts/ad-beech-36-33-amdt-1-pilot-and-co-pilot-seat-tracks-and-seat-frames/conflicts","importantCases":"/api/acts/ad-beech-36-33-amdt-1-pilot-and-co-pilot-seat-tracks-and-seat-frames/important-cases","documents":"/api/acts/ad-beech-36-33-amdt-1-pilot-and-co-pilot-seat-tracks-and-seat-frames/documents"}}
