We are adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440), Model 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 AD was prompted by development of a modification to prevent uncommanded rudder movement during flight. This AD requires modifying the wiring harness of the yaw damper control system. We are issuing this AD to address the unsafe condition on these products.
Within 6,600 flight hours or 36 months after the effective date of this AD, whichever occurs first: Modify the wiring harness of the yaw damper control system, in accordance with the applicable service information specified in table 1 to paragraph (g) of this AD.
