They exist because design flaws or wear patterns have been discovered that could cause accidents if left unaddressed. This instrument ensures these safety requirements remain legally enforceable and up-to-date. The \"revoke and remake\" procedure is a housekeeping measure — it allows CASA to reissue the directives under current legal authority (the 1998 Civil Aviation Safety Regulations) without changing the actual safety requirements."}},"importantCases":[],"_links":{"self":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dornier-228-series-aeroplanes","history":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dornier-228-series-aeroplanes/history","analysis":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dornier-228-series-aeroplanes/analysis","conflicts":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dornier-228-series-aeroplanes/conflicts","importantCases":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dornier-228-series-aeroplanes/important-cases","documents":"/api/acts/airworthiness-directives-2004-revocation-and-remaking-dornier-228-series-aeroplanes/documents"}}
