Airworthiness Directives; Fairchild Aircraft, Inc. SA226 and SA227 Series Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain Fairchild Aircraft, Inc. (Fairchild) SA226 and SA227 series airplanes equipped with Skidmore-Wilheim Manufacturing Co. (Skidmore-Wilheim) (formerly Hydromotive) Model V1-15-1000 brake master cylinders. This AD requires you to replace these brake master cylinders with new or overhauled units of the same design. This AD is the result of reports of dragging brakes during taxi operations. The actions specified by this AD are intended to correct and prevent future malfunctioning brake master cylinders. Malfunctioning brake master cylinders could cause dragging brakes, which can result in overheated brakes and a wheelwell fire if the dragging takes place during takeoff and the gear is later retracted.
