Australian operators must now follow the European directive instead of this cancelled Australian one. This is part of how Australia recognises foreign safety standards to avoid duplicate regulations."}},"importantCases":[],"_links":{"self":"/api/acts/ad-arriel-19-amdt-1-fuel-metering-unit-acceleration-controller-axle-cancelled","history":"/api/acts/ad-arriel-19-amdt-1-fuel-metering-unit-acceleration-controller-axle-cancelled/history","analysis":"/api/acts/ad-arriel-19-amdt-1-fuel-metering-unit-acceleration-controller-axle-cancelled/analysis","conflicts":"/api/acts/ad-arriel-19-amdt-1-fuel-metering-unit-acceleration-controller-axle-cancelled/conflicts","importantCases":"/api/acts/ad-arriel-19-amdt-1-fuel-metering-unit-acceleration-controller-axle-cancelled/important-cases","documents":"/api/acts/ad-arriel-19-amdt-1-fuel-metering-unit-acceleration-controller-axle-cancelled/documents"}}
