Airworthiness Directives are legally binding instructions issued by CASA (the Civil Aviation Safety Authority) that mandate specific maintenance, inspections, or modifications to address unsafe conditions in aircraft. When an AD is revoked, operators no longer need to comply with that specific maintenance requirement—typically because the safety issue has been resolved by design changes, the directive has been superseded by a newer version, or the affected components are no longer in the fleet.\n\n**Why it matters:** This reduces regulatory burden for aircraft operators by removing an outdated compliance obligation, while ensuring the safety regulations remain current and relevant."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-002-12-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-002-12-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-002-12-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-002-12-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-002-12-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-002-12-revocation-of-airworthiness-directives/documents"}}
