This removes the legal obligation for operators to comply with the specific maintenance requirements previously mandated by those directives.\n\n**Why it matters:** Revoking an AD typically happens when a safety issue has been resolved through design changes, the requirement is found to be unnecessary, or it has been replaced by a newer directive. This reduces compliance costs and regulatory burden for operators of these specific aircraft models."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-003-11-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-003-11-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-003-11-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-003-11-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-003-11-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-003-11-revocation-of-airworthiness-directives/documents"}}
