When an AD is revoked, that particular safety requirement no longer applies. This typically occurs when the safety issue has been permanently resolved, the directive has been superseded by a new requirement, or compliance deadlines have passed.\n\nThis instrument was made by a delegate of CASA (Civil Aviation Safety Authority) under the Civil Aviation Safety Regulations."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-025-13-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-025-13-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-025-13-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-025-13-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-025-13-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-025-13-revocation-of-airworthiness-directives/documents"}}
