Specifically, it is **AD/G73/9**, which applies to **Frakes (Grumman) G73 Series Aeroplanes**.\n\n**What it does:**\n- This directive has been **superseded** (replaced) by a newer directive, **AD/G73/21**.\n- Airworthiness Directives are legally binding instructions issued by aviation safety regulators to address unsafe conditions in aircraft, engines, propellers, or other aeronautical products. They typically require owners or operators to perform specific inspections, repairs, or modifications to ensure continued safe operation.\n\n**Who it affects:**\n- Owners and operators of Frakes (Grumman) G73 series aircraft (these are amphibious aircraft, also known as the Grumman G-73 Mallard).\n\n**Why it matters:**\n- Compliance with Airworthiness Directives is mandatory. Even though this particular version (AD/G73/9) has been replaced, it forms part of the regulatory history showing the evolution of safety requirements for this aircraft type. The current applicable requirement is now found in AD/G73/21.\n\n**Key takeaway:** If you operate a Grumman G73, you must follow the current directive AD/G73/21, not this older version."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The entry withdraws AD/G73/9 by superseding it with AD/G73/21.
