This means the requirements in AD/G73/20 are no longer in force, and anyone operating these aircraft must now follow the updated directive instead.\n\n**Why it matters:** Airworthiness Directives are legally binding safety requirements. Failing to comply can ground an aircraft or result in penalties. For maintenance records and historical compliance purposes, knowing which ADs have been superseded helps track what work was required at different points in time."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":true,"description":"The entry explicitly records that AD/G73/20 has been superseded by AD/G73/21, indicating a change in which directive is operative for the Frakes (Grumman) G73 Series.
