It suggests CASA has determined these particular safety mandates are no longer necessary — either because the safety issue has been resolved through other means, the affected aircraft are no longer in service, or newer standards have superseded them.\n\n**When it takes effect:**\nThe instrument itself starts on 8 January 2012, but the actual revocation of the two directives happens on 9 January 2012."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-026-11-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-026-11-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-026-11-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-026-11-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-026-11-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-026-11-revocation-of-airworthiness-directives/documents"}}
