It repeals (cancels) **Airworthiness Directive AD/DO 228/17** effective **6 April 2016**.\n\n**Who it affects**\nOwners and operators of **Dornier 228 aircraft** (the \"DO 228\" in the directive code refers to this German-built twin-turboprop aircraft type).\n\n**What changes**\n* **Before:** Operators had to comply with a specific mandatory inspection, repair, or modification required by Airworthiness Directive AD/DO 228/17.\n* **After 6 April 2016:** That specific directive no longer exists. Operators no longer need to perform whatever maintenance action it mandated.\n\n**Why it matters**\nThis reduces regulatory burden and maintenance costs for Dornier 228 operators. The Civil Aviation Safety Authority (CASA) has determined that the safety risk addressed by the old directive is now adequately managed through other means, the affected components are no longer in widespread use, or the original safety issue has been resolved."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-008-16-repeal-of-airworthiness-directive","history":"/api/acts/casa-adcx-008-16-repeal-of-airworthiness-directive/history","analysis":"/api/acts/casa-adcx-008-16-repeal-of-airworthiness-directive/analysis","conflicts":"/api/acts/casa-adcx-008-16-repeal-of-airworthiness-directive/conflicts","importantCases":"/api/acts/casa-adcx-008-16-repeal-of-airworthiness-directive/important-cases","documents":"/api/acts/casa-adcx-008-16-repeal-of-airworthiness-directive/documents"}}
