They ground aircraft or mandate repairs when design flaws are discovered. This particular AD addressed a structural concern that could affect flight safety. Its removal simply reflects that the specific aircraft type is no longer operated in Australia, not that the safety issue was resolved."}},"importantCases":[],"_links":{"self":"/api/acts/ad-hs-125-84-canopy-upper-rail","history":"/api/acts/ad-hs-125-84-canopy-upper-rail/history","analysis":"/api/acts/ad-hs-125-84-canopy-upper-rail/analysis","conflicts":"/api/acts/ad-hs-125-84-canopy-upper-rail/conflicts","importantCases":"/api/acts/ad-hs-125-84-canopy-upper-rail/important-cases","documents":"/api/acts/ad-hs-125-84-canopy-upper-rail/documents"}}
