An Airworthiness Directive is a mandatory safety notice issued by the Civil Aviation Safety Authority (CASA) requiring aircraft owners or operators to perform specific maintenance or inspections to address unsafe conditions.\n\n**What this does:**\n*   Cancels **AD/BAe 146/43** effective 15 July 2010\n*   Cancels **AD/BAe 146/107 Amendment 3** effective 16 July 2010\n\n**Who is affected:**\nOwners and operators of British Aerospace 146 aircraft who were previously required to comply with these two specific safety directives.\n\n**Why this matters:**\nOnce revoked, the maintenance or inspection requirements contained in these directives are no longer legally mandatory. This typically occurs when the safety issue has been resolved through design changes, the directive has been superseded by newer requirements, or CASA has determined the directive is no longer necessary for airworthiness."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-018-10-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-018-10-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-018-10-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-018-10-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-018-10-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-018-10-revocation-of-airworthiness-directives/documents"}}
