Under Australian regulations (CASR 39.001A), FAA directives issued after 1 October 2009 are automatically recognised as binding in Australia, making the local directive redundant.\n\n**Who is affected:** Aircraft owners and operators with General Electric CF34 series engines. They must now follow the FAA directive instead of this cancelled Australian directive."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cf34-16-fadec-software-version-8ev5-40-cancelled","history":"/api/acts/ad-cf34-16-fadec-software-version-8ev5-40-cancelled/history","analysis":"/api/acts/ad-cf34-16-fadec-software-version-8ev5-40-cancelled/analysis","conflicts":"/api/acts/ad-cf34-16-fadec-software-version-8ev5-40-cancelled/conflicts","importantCases":"/api/acts/ad-cf34-16-fadec-software-version-8ev5-40-cancelled/important-cases","documents":"/api/acts/ad-cf34-16-fadec-software-version-8ev5-40-cancelled/documents"}}
