## Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. This proposed AD was prompted by reports of in-flight uncommanded rudder movements. This proposed AD would require revising the airplane flight manual (AFM) to incorporate an uncommanded yaw motion procedure. We are proposing this AD to prevent in-flight uncommanded rudder movements, which could lead to structural failure and subsequent loss of the airplane.
