When the safety issue is resolved (for example, through fleet modifications or new data showing the risk no longer exists), CASA cancels the directive to remove unnecessary regulatory burdens and compliance costs from the aviation industry."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-021-14-repeal-of-airworthiness-directive","history":"/api/acts/casa-adcx-021-14-repeal-of-airworthiness-directive/history","analysis":"/api/acts/casa-adcx-021-14-repeal-of-airworthiness-directive/analysis","conflicts":"/api/acts/casa-adcx-021-14-repeal-of-airworthiness-directive/conflicts","importantCases":"/api/acts/casa-adcx-021-14-repeal-of-airworthiness-directive/important-cases","documents":"/api/acts/casa-adcx-021-14-repeal-of-airworthiness-directive/documents"}}
