The original scope, as indicated by the AD title, was to require inspection of flap hinge levers on British Aerospace BAe 125 series aeroplanes (AD/HS 125/29 — Flap Hinge Levers - Inspection). The current entry states that the AD has been removed from the listing because the aircraft model is not on the Australian register (\"This AD contents has been removed from the listing because the aircraft model is not currently on the register\"). Mechanically, that changes the on-the-ground scope in Australia from an active listed inspection requirement (for registered BAe 125s) to no active listing-based requirement while the model remains unregistered; the directive’s technical scope could be reinstated if the model reappears on the register or if CASA issues a new AD."},"complexity_factors":["Very short directive entry with minimal text and no technical inspection detail.","Applicability conditioned on register status (removal because model not on the register).","Lack of specified inspection procedure, intervals, corrective actions or compliance timeline in the provided text.","Regulatory discretion evident (removal from listing) but without explanation of reactivation criteria.","Potential external substitution effects (same AD may be active in other jurisdictions) not addressed in text."],"plain_english_summary":"AD/HS 125/29 required inspection of flap hinge levers on British Aerospace BAe 125 series aircraft to address an airworthiness concern.

Flap hinge levers are mechanical components that help control the flaps — the movable surfaces on wings that help aircraft slow down and land safely.\n\n**Current status:**\nThe directive's contents have been **removed from the active register** because no BAe 125 aircraft are currently registered in Australia. This means there's no fleet to inspect, so the directive sits dormant.\n\n**Who it affects:**\n- Previously: Owners and operators of British Aerospace BAe 125 series aircraft in Australia\n- Currently: Nobody, unless someone re-registers this aircraft type\n\n**Why it matters:**\nAirworthiness directives exist to prevent accidents. Even though this one is inactive, it demonstrates how aviation safety works — mechanical defects get identified, mandatory inspections get issued, and when aircraft types leave the fleet, the rules get shelved. If someone imports or re-registers a BAe 125 in Australia, this directive would likely be reactivated."}},"importantCases":[],"_links":{"self":"/api/acts/ad-hs-125-29-flap-hinge-levers-inspection","history":"/api/acts/ad-hs-125-29-flap-hinge-levers-inspection/history","analysis":"/api/acts/ad-hs-125-29-flap-hinge-levers-inspection/analysis","conflicts":"/api/acts/ad-hs-125-29-flap-hinge-levers-inspection/conflicts","importantCases":"/api/acts/ad-hs-125-29-flap-hinge-levers-inspection/important-cases","documents":"/api/acts/ad-hs-125-29-flap-hinge-levers-inspection/documents"}}
