Full official abstract
This amendment adopts a new airworthiness directive (AD) that applies to certain Fairchild Aircraft SA226 and SA227 series airplanes. This AD requires you to replace the brake shuttle valves with parts of improved design and install a shield over the hydraulic lines. This AD also requires replacing the rubber fuel hose with a metal device for certain SA226 series airplanes. This AD is the result of a report of a wheel brake system malfunction caused by a faulty brake shuttle valve. The actions specified by this AD are intended to correct potential brake shuttle valve problems, which could cause the brake assembly to drag and overheat. Hydraulic or fuel line damage could then occur if the overheated brake assembly is retracted into the main wheel well, with a consequent fire if the hydraulic or fuel lines ruptured.
