The modification was identified as \"6/69\".\n\n**What it is now:** The directive has been **removed from active use** because the aircraft model it applies to — the British Aerospace BAe 125 Series — is **no longer registered in Australia**. In other words, there are no planes of this type currently flying under Australian registration, so the safety rule no longer needs to be enforced.\n\n**Who it affects:** Nobody, currently. It previously affected operators and maintainers of BAe 125 Series aircraft in Australia.\n\n**Why it matters:** This shows how aviation safety regulations are kept current. When aircraft types are retired or deregistered, associated safety directives are cleaned up rather than left cluttering the rulebooks."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The original entry title indicates the AD would apply to British Aerospace BAe 125 series aeroplanes for a hydraulic flow indicator modification (source: \"AD/HS 125/17 Hydraulic Flow Indicator - Modification\").
