If they fail or leak, a fire in the engine or cabin could become uncontrollable. This AD ensured these bottles were checked properly.\n\n**Current status:**\nThe directive has been **removed from active use** because no BAe 125 aircraft are currently registered in Australia. CASA has essentially archived it — there's no point enforcing a safety rule on planes that aren't flying here anymore."}},"importantCases":[],"_links":{"self":"/api/acts/ad-hs-125-36-fire-extinguisher-bottles-inspection","history":"/api/acts/ad-hs-125-36-fire-extinguisher-bottles-inspection/history","analysis":"/api/acts/ad-hs-125-36-fire-extinguisher-bottles-inspection/analysis","conflicts":"/api/acts/ad-hs-125-36-fire-extinguisher-bottles-inspection/conflicts","importantCases":"/api/acts/ad-hs-125-36-fire-extinguisher-bottles-inspection/important-cases","documents":"/api/acts/ad-hs-125-36-fire-extinguisher-bottles-inspection/documents"}}
