When safety issues are permanently resolved, superseded by newer rules, or become irrelevant, CASA revokes them to reduce regulatory clutter and prevent confusion for pilots, aircraft owners, and maintenance engineers.\n\n**Who is affected:**\nAircraft operators, owners, and maintenance organisations who were previously required to comply with these specific general-category directives. Once revoked, the requirements in these directives no longer apply."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-031-10-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-031-10-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-031-10-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-031-10-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-031-10-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-031-10-revocation-of-airworthiness-directives/documents"}}
