Airworthiness Directives; Bombardier, Inc., Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (CL-604 Variant) airplanes. This AD was prompted by reports of in-flight uncommanded rudder movements on airplanes with an installation similar to the installation on certain Model CL-600-2B16 (CL-604 Variant) airplanes. This AD requires modification of the wiring harness for the yaw damper control system. We are issuing this AD to address the unsafe condition on these products.
