Once the revocation dates pass, these requirements no longer apply.\n\n**Why it matters**\nThis is regulatory \"housekeeping\" that removes outdated or superseded safety requirements. It reduces compliance costs and paperwork for the aviation industry without creating any new obligations."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-027-11-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-027-11-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-027-11-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-027-11-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-027-11-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-027-11-revocation-of-airworthiness-directives/documents"}}
