As of 17 January 2012, that particular requirement no longer applies. Operators no longer need to comply with that specific directive, though all other safety regulations remain in force.\n\n**Why it matters:** Airworthiness Directives are legally binding safety instructions issued when unsafe conditions are found in aircraft. Revoking one typically occurs when the safety issue has been resolved, superseded by an updated rule, or deemed no longer necessary based on new evidence."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-025-11-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-025-11-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-025-11-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-025-11-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-025-11-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-025-11-revocation-of-airworthiness-directives/documents"}}
