This instrument ensures the Winjeel's rudder pulley bracket (a component that helps control the aircraft's steering) continues to be inspected and maintained to current safety standards. The \"revoke and remake\" process is a housekeeping measure—likely done to reissue the directive under updated legal authority or to correct administrative details—while keeping the actual safety requirements exactly the same.\n\n**Key point:** The safety requirements haven't changed. This is purely administrative maintenance of the regulatory framework."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-c-a-c-ca-25-winjeel-series-aeroplanes","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-c-a-c-ca-25-winjeel-series-aeroplanes/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-c-a-c-ca-25-winjeel-series-aeroplanes/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-c-a-c-ca-25-winjeel-series-aeroplanes/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-c-a-c-ca-25-winjeel-series-aeroplanes/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-c-a-c-ca-25-winjeel-series-aeroplanes/documents"}}
