Summary

We propose to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440), CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), and Model CL-600-2D24 (Regional Jet Series 900) airplanes. This proposed AD was prompted by development of a modification to prevent uncommanded rudder movement during flight. This proposed AD would require modifying the wiring harness of the yaw damper control system. We are proposing this AD to address the unsafe condition on these products.
