This marker prevents confusion by clearly stating that AD/G73/8 is no longer valid and pointing to the current replacement.\n- Anyone researching historical compliance or investigating incidents involving G73 aircraft would use this to trace which safety rules applied at different times.\n\n**In short:** This isn't the actual safety rule itself—it's a signpost telling aviation professionals to look at AD/G73/21 instead."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":true,"description":"The supplied Schedule entry explicitly records that AD/G73/8 has been superseded by AD/G73/21 (text: “AD/G73/8  Superseded by AD/G73/21”).
