ADs are legally binding safety orders issued by the Civil Aviation Safety Authority (CASA) that require aircraft owners and operators to perform specific maintenance, inspections, or modifications to address unsafe conditions.\n\n**Who it affects**\n\nAircraft operators, owners, and maintenance organisations responsible for:\n*   **Rolls-Royce AE 3007 engines** (specifically AD/AE 3007/6 Amdt 2)\n*   **Airbus A330 aircraft** (AD/A330/89)\n*   **Cessna 750 Citation X aircraft** (AD/CESSNA 750/4)\n*   **MBB/Kawasaki BK 117 helicopters** (AD/JBK 117/30)\n\n**Why it matters**\n\nFrom the dates specified in the Schedule (between 6 October and 1 November 2010), the mandatory maintenance requirements imposed by these four directives ceased to apply. Revocations typically occur when the safety issue has been resolved through design changes, alternative regulatory measures, or when the directive is no longer considered necessary for airworthiness."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-025-10-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-025-10-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-025-10-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-025-10-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-025-10-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-025-10-revocation-of-airworthiness-directives/documents"}}
