This AD applies to all MHI RJ Aviation ULC (Type Certificate previously held by Bombardier, Inc.) airplanes, certificated in any category, as identified in paragraphs (c)(1) through (6) of this AD.
(1) Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes.
(2) Model CL-600-2C10 (Regional Jet Series 700, 701, and 702) airplanes.
(3) Model CL-600-2C11 (Regional Jet Series 550) airplanes.
(4) Model CL-600-2D15 (Regional Jet Series 705) airplanes.
(5) Model CL-600-2D24 (Regional Jet Series 900) airplanes.

The FAA is adopting a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440), CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by multiple reports of elevator autopilot control cable failure. This AD requires replacing the elevator autopilot control cables. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada AD CF-2025-63, dated November 28, 2025 (Transport Canada AD CF-2025-63).
Where Transport Canada AD CF-2025-63 specifies to do the actions within the compliance time shown in Table 1 of Transport Canada AD CF-2025-63, for this AD, the actions must be done within the applicable compliance times identified in Figure 1 to paragraph (h) of this AD.
