This means a specific maintenance instruction or inspection requirement previously mandated for these aircraft is no longer legally required.\n\n**Why it matters:** Airworthiness Directives are legally binding safety instructions issued by the Civil Aviation Safety Authority (CASA). Removing one typically means the safety issue has been resolved through other means, the requirement is obsolete, or it has been replaced by a different rule."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-014-15-repeal-of-airworthiness-directive","history":"/api/acts/casa-adcx-014-15-repeal-of-airworthiness-directive/history","analysis":"/api/acts/casa-adcx-014-15-repeal-of-airworthiness-directive/analysis","conflicts":"/api/acts/casa-adcx-014-15-repeal-of-airworthiness-directive/conflicts","importantCases":"/api/acts/casa-adcx-014-15-repeal-of-airworthiness-directive/important-cases","documents":"/api/acts/casa-adcx-014-15-repeal-of-airworthiness-directive/documents"}}
