The tailcone is essential for aircraft structural integrity. The directive ensures these specific aircraft meet current safety standards following production changes in later models.\n\n**Key points:**\n- **Compliance deadline:** As specified in the Cessna service letter (not stated in this document itself).\n- **Credit for prior work:** If you already did inspections under earlier versions of this directive, those count toward compliance.\n- **This is Amendment 2:** The directive was updated to account for manufacturing changes in newer aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-207-7-amdt-2-aft-tailcone-assembly","history":"/api/acts/ad-cessna-207-7-amdt-2-aft-tailcone-assembly/history","analysis":"/api/acts/ad-cessna-207-7-amdt-2-aft-tailcone-assembly/analysis","conflicts":"/api/acts/ad-cessna-207-7-amdt-2-aft-tailcone-assembly/conflicts","importantCases":"/api/acts/ad-cessna-207-7-amdt-2-aft-tailcone-assembly/important-cases","documents":"/api/acts/ad-cessna-207-7-amdt-2-aft-tailcone-assembly/documents"}}
