2023-25-06: Landing gear

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: 2023-25-06 Saab AB, Support and Services (Formerly Known as Saab AB, Saab Aeronautics): Amendment 39-22633; Docket No. FAA-2023-1896; Project Identifier MCAI-2023-00837-T. (a) Effective Date This airworthiness directive (AD) is effective February 7, 2024. (b) Affected ADs None. (c) Applicability This AD applies to all Saab AB, Support and Services (formerly known as Saab AB, Saab Aeronautics) Model SAAB 2000 airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. (e) Unsafe Condition This AD was prompted by a review of the anti-skid system that revealed the possibility of inadvertently connecting the inboard harness to the outboard channel (and vice versa) of the wheel speed transducers in the main landing gear (MLG) wheel axles. The FAA is issuing this AD to address incorrect connections of the harnesses to the wheel speed transducers. The unsafe condition, if not addressed, could result in wrong inputs to the anti-skid function, whenever activated, with consequent reduced braking capability, possibly resulting in damage to the airplane. (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, EASA AD 2023-0135, dated July 10, 2023 (EASA AD 2023-0135). (h) Exceptions to EASA AD 2023-0135 (1) Where EASA AD 2023-0135 refers to its effective date, this AD requires using the effective date of this AD. (2) Where EASA AD 2023-0135 requires a "visual check," this AD requires replacing those words with "visual inspection." (3) This AD does not adopt the "Remarks" section of EASA AD 2023-0135. (i) 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.
