If they break during flight, the pilot could lose control of the aircraft. These mandatory checks catch wear and tear before it causes an accident."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-185-1-amdt-2-plastic-control-wheel","history":"/api/acts/ad-cessna-185-1-amdt-2-plastic-control-wheel/history","analysis":"/api/acts/ad-cessna-185-1-amdt-2-plastic-control-wheel/analysis","conflicts":"/api/acts/ad-cessna-185-1-amdt-2-plastic-control-wheel/conflicts","importantCases":"/api/acts/ad-cessna-185-1-amdt-2-plastic-control-wheel/important-cases","documents":"/api/acts/ad-cessna-185-1-amdt-2-plastic-control-wheel/documents"}}
