When CASA repeals one, it means the specific repair, inspection, or modification requirement is no longer legally required—typically because the safety risk has been resolved, the rule has been replaced, or it has become obsolete. Operators of BAe 146 aircraft will no longer need to comply with the specific requirements outlined in the old directive."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-019-16-repeal-of-airworthiness-directive","history":"/api/acts/casa-adcx-019-16-repeal-of-airworthiness-directive/history","analysis":"/api/acts/casa-adcx-019-16-repeal-of-airworthiness-directive/analysis","conflicts":"/api/acts/casa-adcx-019-16-repeal-of-airworthiness-directive/conflicts","importantCases":"/api/acts/casa-adcx-019-16-repeal-of-airworthiness-directive/important-cases","documents":"/api/acts/casa-adcx-019-16-repeal-of-airworthiness-directive/documents"}}
