It **revokes** (cancels) two existing Airworthiness Directives (ADs) for Diamond HK-36 series aeroplanes and **immediately remakes** them as separate, standalone legal instruments.\n\n**Who it affects:**\n- Owners and operators of Diamond HK-36 series aeroplanes (motor gliders)\n- Maintenance organisations servicing these aircraft\n- The Civil Aviation Safety Authority (CASA), which issues safety mandates\n\n**Why it matters:**\nAirworthiness Directives are legally binding safety orders. They require specific inspections, repairs, or modifications to address unsafe conditions in aircraft. This instrument doesn't change the actual safety requirements — the two ADs remain identical in content to their previous versions. Instead, it changes their legal form: rather than being grouped together in a 2004 compilation, each AD now exists as its own separate instrument.\n\nThis matters because:\n- It makes the ADs easier to find and reference individually\n- It aligns with CASA's practice of issuing ADs as standalone instruments\n- It ensures the safety requirements remain enforceable under current regulations\n\n**The two ADs covered:**\n- **AD/DIMO/1**: Addresses software issues in the turbocharger control unit\n- **AD/DIMO/2**: Addresses the aileron control system push rods (components that help steer the aircraft)"},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The instrument does not change the substantive requirements applicable to Diamond HK-36 series aeroplanes. It revokes the listed Airworthiness Directives and re‑makes each as a separate instrument \"in exactly the same form as appears in the latest published edition of the Directive\" (Note).
