Under Australian aviation regulations (CASR Part 39.001A), European airworthiness directives issued after 1 October 2009 automatically apply as Australian law, making the separate local directive redundant."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bn-2-85-amdt-1-elevator-tip-assemblies-cancelled","history":"/api/acts/ad-bn-2-85-amdt-1-elevator-tip-assemblies-cancelled/history","analysis":"/api/acts/ad-bn-2-85-amdt-1-elevator-tip-assemblies-cancelled/analysis","conflicts":"/api/acts/ad-bn-2-85-amdt-1-elevator-tip-assemblies-cancelled/conflicts","importantCases":"/api/acts/ad-bn-2-85-amdt-1-elevator-tip-assemblies-cancelled/important-cases","documents":"/api/acts/ad-bn-2-85-amdt-1-elevator-tip-assemblies-cancelled/documents"}}
