Airworthiness Directives; Canadair Model CL-600-2A12 (CL-601) and CL-600-2B16 (CL-601-3A) Series Airplanes

الملخص

This amendment adopts a new airworthiness directive (AD), applicable to certain Canadair Model CL-600-2A12 and CL-600-2B16 series airplanes, that requires a one-time visual inspection to verify proper installation of shoulder bolts and to detect damage of the adjacent flap actuator housings, and correction of discrepancies. This amendment is prompted by a report of failure of the flap actuator on the left wing inboard flap. The actions specified by this AD are intended to prevent asymmetric deployment or retraction (blow back) of the flaps, which could reduce controllability of the airplane.
