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 affected:** Frakes (Grumman) G73 Series Aeroplanes (also known as Grumman Mallard amphibious aircraft)\n- **Directive number:** AD/G73/19\n- **Status:** This directive has been **replaced** by a newer version (AD/G73/21)\n\n**Why it matters:**\nAirworthiness Directives are legally binding safety requirements. Aircraft cannot legally fly unless they comply with all applicable ADs. When an AD is \"superseded,\" it means the old requirements have been updated, expanded, or replaced by new ones. Operators must follow the current version (AD/G73/21) rather than this outdated one.\n\n**Key takeaway:** This is essentially a placeholder or historical reference indicating that the safety requirements for these Grumman G73 aircraft have been updated, and anyone responsible for maintaining or operating these planes should consult the current directive AD/G73/21 instead."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":true,"description":"The supplied entry records that AD/G73/19 has been superseded by AD/G73/21 (source: \"AD/G73/19 Superseded by AD/G73/21\").
