2026-02-03: Flight control

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2026-02-03 MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.): Amendment 39-23239; Docket No. FAA-2026-0013; Project Identifier MCAI-2025-01774-T. (a) Effective Date This airworthiness directive (AD) is effective February 5, 2026. (b) Affected ADs None. (c) Applicability 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. (6) Model CL-600-2E25 (Regional Jet Series 1000) airplanes. (d) Subject Air Transport Association (ATA) of America Code 27, Flight control. (e) Unsafe Condition This AD was prompted by multiple reports of elevator autopilot control cable failure. The FAA is issuing this AD to address elevator autopilot control cable failure. The unsafe condition, if not addressed, could result in jamming of the elevator servo drum, restricting elevator movement in one direction. An elevator servo drum jam during the landing phase can result in insufficient elevator control authority and could lead to loss of continued safe flight and landing. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements 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). (h) Exception to 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. Figure 1 to Paragraph ( h )-Compliance Time Airplane model Elevator autopilot control cable total flight hours as of the effective date of this AD a Compliance time CL-600-2C10, CL-600-2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25 More than 40,000 5 months (after the effective date of this AD). Between 25,000 and 40,000 11 months (after the effective date of this AD). Between 20,500 and 24,999 15 months (after the effective date of this AD). Between 12,000 and 20,499 20 months (after the effective date of this AD). Less than 12,000 Before the elevator autopilot control cables reach 16,000 total flight hours. CL-600-2B19 More than 40,000 11 months (after the effective date of this AD). Between 12,000 and 40,000 15 months (after the effective date of this AD). Less than 12,000 Before the elevator autopilot control cables reach 16,000 total flight hours. a If elevator autopilot cable total flight hours cannot be demonstrated, airplane total flight hours since entry into service must be used to determine compliance time. (i) Special Flight Permits Special flight permits may be issued in accordance with 14 CFR 21.197 and 21.199 to operate the airplane to a location where the airplane can be modified (if the operator elects to do so), provided no passengers are onboard. (j) Additional AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
