An Airworthiness Directive is a mandatory safety notice issued by the Civil Aviation Safety Authority (CASA) that requires aircraft owners or operators to perform specific inspections, repairs, or modifications to address unsafe conditions.\n\n**What this document shows:**\n- **Aircraft type:** Frakes (Grumman) G73 Series Aeroplanes (also known as Grumman Mallard amphibious aircraft)\n- **Directive number:** AD/G73/16\n- **Status:** **Superseded** — meaning this directive has been replaced by a newer version (AD/G73/21)\n- **Issuing body:** Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998\n\n**Why it matters:**\nAirworthiness Directives are legally binding safety requirements. When an AD is superseded, aircraft operators must follow the newer directive (AD/G73/21 in this case) rather than this older one. This document serves as a historical reference point showing the regulatory lineage of safety requirements for these particular aircraft.\n\n**Note:** The actual technical content of the directive (what specific action was required, why it was needed, compliance deadlines) is not present in this fragment — this appears to be a header or navigation page only."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The recorded scope of AD/G73/16 has changed in that this entry is marked as superseded by AD/G73/21.
