Specifically, it repeals (removes) Airworthiness Directive **AD/A320/79 Amdt 2** effective 27 May 2015.\n\n**Who it affects**\nThis affects airlines, charter operators, and private owners who operate Airbus A320 aircraft that were previously required to comply with the repealed directive.\n\n**Why it matters**\nAirworthiness Directives (legally binding safety instructions issued when aircraft have potentially unsafe conditions) impose mandatory maintenance, inspection, or modification requirements. Repealing one typically means the safety issue has been resolved—perhaps through manufacturer design changes, new technical evidence showing the risk no longer exists, or the affected fleet being modified. Once repealed, operators are no longer legally required to follow the specific compliance actions outlined in the old directive, potentially reducing maintenance costs and administrative burden."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-006-15-repeal-of-airworthiness-directive","history":"/api/acts/casa-adcx-006-15-repeal-of-airworthiness-directive/history","analysis":"/api/acts/casa-adcx-006-15-repeal-of-airworthiness-directive/analysis","conflicts":"/api/acts/casa-adcx-006-15-repeal-of-airworthiness-directive/conflicts","importantCases":"/api/acts/casa-adcx-006-15-repeal-of-airworthiness-directive/important-cases","documents":"/api/acts/casa-adcx-006-15-repeal-of-airworthiness-directive/documents"}}
