The FAA issued a new directive in November 2009 that supersedes the old one. Under Australian law, when the country of manufacture (the \"State of Design\") issues a new safety directive after 1 October 2009, it automatically applies in Australia. This makes the old separate Australian requirement redundant, so the Civil Aviation Safety Authority is cancelling it to avoid duplication."}},"importantCases":[],"_links":{"self":"/api/acts/ad-jt8d-16-amdt-2-second-stage-fan-blades-cancelled","history":"/api/acts/ad-jt8d-16-amdt-2-second-stage-fan-blades-cancelled/history","analysis":"/api/acts/ad-jt8d-16-amdt-2-second-stage-fan-blades-cancelled/analysis","conflicts":"/api/acts/ad-jt8d-16-amdt-2-second-stage-fan-blades-cancelled/conflicts","importantCases":"/api/acts/ad-jt8d-16-amdt-2-second-stage-fan-blades-cancelled/important-cases","documents":"/api/acts/ad-jt8d-16-amdt-2-second-stage-fan-blades-cancelled/documents"}}
