This typically occurs when the safety issue has been resolved through design changes, when a newer directive replaces the old one, or when the affected aircraft fleet has been retired from Australian service."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-007-11-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-007-11-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-007-11-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-007-11-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-007-11-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-007-11-revocation-of-airworthiness-directives/documents"}}
