Two directives are cancelled immediately on 29 September 2013, and two others are cancelled a few weeks later on 18 October 2013.\n\n**Why this matters:** Removing outdated directives reduces unnecessary maintenance burdens and compliance costs for operators, provided CASA has determined these safety requirements are no longer needed (perhaps because newer directives replace them, or the safety issue has been resolved through other means)."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-019-13-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-019-13-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-019-13-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-019-13-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-019-13-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-019-13-revocation-of-airworthiness-directives/documents"}}
