While operators must still comply with all other safety regulations, they no longer need to perform the specific corrective actions previously required by these two directives. This typically occurs when the safety issue has been resolved through design changes, equipment has been retired, or newer standards have replaced the old requirements."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-019-12-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-019-12-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-019-12-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-019-12-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-019-12-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-019-12-revocation-of-airworthiness-directives/documents"}}
