No. 8\n\n**What you must do:**\n- Inspect the \"NK Inner Shell\" of the combustion chamber for cracks, wear, or damage that could cause engine failure\n\n**When:**\n- At least every **100 hours of flight time** (time in service)\n\n**How:**\n- Follow the technical procedures in **Turbomeca Service Bulletin No. 72.218.0018**, or alternatively comply with the older directive **AD/TURB-T/1**\n\nThis rule exists to catch deterioration in this critical high-temperature component before it leads to catastrophic engine failure."}},"importantCases":[],"_links":{"self":"/api/acts/ad-artouste-3-combustion-chamber-inner-shell-inspection","history":"/api/acts/ad-artouste-3-combustion-chamber-inner-shell-inspection/history","analysis":"/api/acts/ad-artouste-3-combustion-chamber-inner-shell-inspection/analysis","conflicts":"/api/acts/ad-artouste-3-combustion-chamber-inner-shell-inspection/conflicts","importantCases":"/api/acts/ad-artouste-3-combustion-chamber-inner-shell-inspection/important-cases","documents":"/api/acts/ad-artouste-3-combustion-chamber-inner-shell-inspection/documents"}}
