This typically happens when the safety issues have been resolved through design modifications, newer directives have replaced the old ones, or the affected aircraft are being retired from service.\n\n**Why it matters:**\nRemoving obsolete rules reduces paperwork and compliance costs for aviation businesses while maintaining safety standards through more current regulations."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-018-14-repeal-of-airworthiness-directives","history":"/api/acts/casa-adcx-018-14-repeal-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-018-14-repeal-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-018-14-repeal-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-018-14-repeal-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-018-14-repeal-of-airworthiness-directives/documents"}}
