This means affected operators no longer need to follow the maintenance or inspection requirements contained in these particular directives, reducing administrative burden and costs assuming previous requirements have been met."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-019-11-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-019-11-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-019-11-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-019-11-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-019-11-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-019-11-revocation-of-airworthiness-directives/documents"}}
