Instead, a European safety rule (EASA AD 2009-0249) now applies to these aircraft. Under Australian aviation regulations (CASR 30.001A), European safety directives issued after 1 October 2009 are automatically recognised as Australian law for imported aircraft, making the old local rule redundant."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pc-12-58-air-data-attitude-heading-reference-system-cancelled","history":"/api/acts/ad-pc-12-58-air-data-attitude-heading-reference-system-cancelled/history","analysis":"/api/acts/ad-pc-12-58-air-data-attitude-heading-reference-system-cancelled/analysis","conflicts":"/api/acts/ad-pc-12-58-air-data-attitude-heading-reference-system-cancelled/conflicts","importantCases":"/api/acts/ad-pc-12-58-air-data-attitude-heading-reference-system-cancelled/important-cases","documents":"/api/acts/ad-pc-12-58-air-data-attitude-heading-reference-system-cancelled/documents"}}
