Even though this particular AD is inactive now, it shows how aviation safety works — when a potential defect is found (in this case, possibly with oxygen cylinders that supply emergency breathing masks), regulators issue mandatory inspection orders. If a BAe 125 were ever re-registered in Australia, this AD might be reactivated or replaced with updated requirements."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The operative scope has been narrowed compared with an active AD: the entry has been removed from the Schedule on the ground that the BAe 125 model is not on the Australian register (quoted sentence).
