These are mandatory safety instructions issued by the Civil Aviation Safety Authority (CASA) that require aircraft owners to perform specific maintenance or modifications to keep their planes safe to fly.\n\n**What's being removed**\nThe document removes the following requirements:\n* **AD/CF6/16, AD/CF6/22 and AD/CF6/73** — Three rules affecting **CF6 jet engines** (engines commonly used on Boeing 747, 767 and Airbus A300 aircraft). These end on **28 November 2014**.\n* **AD/B737/243** — One rule affecting **Boeing 737 aircraft**, ending on **17 December 2014**.\n\n**Why it matters**\nThis clears out outdated regulations, reducing paperwork and compliance costs for airlines and maintenance companies. The safety issues these rules originally addressed have likely been resolved through newer directives or design improvements."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-019-14-repeal-of-airworthiness-directives","history":"/api/acts/casa-adcx-019-14-repeal-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-019-14-repeal-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-019-14-repeal-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-019-14-repeal-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-019-14-repeal-of-airworthiness-directives/documents"}}
