Rather than keeping an outdated requirement, the Civil Aviation Safety Authority cancelled the Australian rule entirely. Operators must now comply with the new American directive (FAA AD 2009-26-09) instead of this cancelled Australian rule."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cf34-5-amdt-3-fan-disks-cancelled","history":"/api/acts/ad-cf34-5-amdt-3-fan-disks-cancelled/history","analysis":"/api/acts/ad-cf34-5-amdt-3-fan-disks-cancelled/analysis","conflicts":"/api/acts/ad-cf34-5-amdt-3-fan-disks-cancelled/conflicts","importantCases":"/api/acts/ad-cf34-5-amdt-3-fan-disks-cancelled/important-cases","documents":"/api/acts/ad-cf34-5-amdt-3-fan-disks-cancelled/documents"}}
