It requires owners and operators of certain Bell and Agusta-Bell helicopters to inspect a specific part called the **pylon support link** (part number 206-031-508).\n\n**What it does:**\n- Mandates inspection of a critical structural component that connects the helicopter's body to its tail boom\n- Applies to all Bell 206 and Agusta-Bell 206 series helicopters\n- Requires compliance with Bell Service Bulletin 206-01-73-2 (Revision A)\n\n**Who it affects:**\n- Owners and operators of Bell 206 and Agusta-Bell 206 helicopters\n- Maintenance organisations servicing these aircraft\n\n**Why it matters:**\nThe pylon support link is vital for structural integrity. Failure could lead to catastrophic separation of the tail section. This directive ensures potential cracks or defects are found before they cause accidents. The \"Amdt 2\" indicates this is the second revision, suggesting ongoing safety monitoring of this component."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The AD text supplied does not state any change of applicability or scope within the body of the instrument; it identifies applicability as 'All models' and delegates procedural detail to Bell SB No. 206-01-73-2, Rev.
