Instead of following separate Australian rules, affected operators now comply directly with the European regulation. This simplifies compliance by aligning Australian requirements with the engine manufacturer's home jurisdiction (France)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-arriel-34-module-m05-lubrication-duct-cancelled","history":"/api/acts/ad-arriel-34-module-m05-lubrication-duct-cancelled/history","analysis":"/api/acts/ad-arriel-34-module-m05-lubrication-duct-cancelled/analysis","conflicts":"/api/acts/ad-arriel-34-module-m05-lubrication-duct-cancelled/conflicts","importantCases":"/api/acts/ad-arriel-34-module-m05-lubrication-duct-cancelled/important-cases","documents":"/api/acts/ad-arriel-34-module-m05-lubrication-duct-cancelled/documents"}}
