This means there are no BAe 125 aircraft currently on the Australian civil aircraft register, so the safety requirement no longer needs to be enforced.\n\n**Why this matters:**\nAirworthiness Directives are legally binding safety instructions. When an aircraft type leaves the Australian register (through retirement, export, or deregistration), related directives are typically withdrawn or marked as removed since there are no affected operators to comply. This keeps the regulatory framework clean and avoids imposing obligations on non-existent aircraft."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The original scope (an AD requiring inspection of flexible hydraulic hoses on BAe 125 series aeroplanes) has been narrowed in practice: the AD entry has been removed from the published listing because the BAe 125 is not currently on the Australian register.
