When an AD is revoked, those specific repair or inspection requirements no longer apply—typically because the safety issue has been resolved through design changes, the affected parts are no longer in use, or newer directives have superseded the old ones.\n\nThis instrument takes effect on **24 April 2013** and was issued by a CASA (Civil Aviation Safety Authority) delegate under aviation safety regulations."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-006-13-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-006-13-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-006-13-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-006-13-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-006-13-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-006-13-revocation-of-airworthiness-directives/documents"}}
