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: 2025-20-01 ATR-GIE Avions de Transport Régional: Amendment 39-23154; Docket No. FAA-2025-1354; Project Identifier MCAI-2025-00012-T. (a) Effective Date This airworthiness directive (AD) is effective November 6, 2025. (b) Affected ADs None. (c) Applicability This AD applies to the ATR-GIE Avions de Transport Régional airplanes identified in paragraphs (c)(1) and (2) of this AD, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2025-0004, dated January 7, 2025 (EASA AD 2025-0004). (1) ATR42-500 airplanes. (2) ATR72-101, -102, -201, -202, -211, -212, and -212A airplanes. (d) Subject Air Transport Association (ATA) of America Code 27, Flight Controls. (e) Unsafe Condition This AD was prompted by an investigation indicating that an erroneous monitoring of the travel limitation unit (TLU) could occur when the airplane is flying above a certain speed as a result of the logic input from either air data computer (ADC) 1 or ADC2 input. The FAA is issuing this AD to address this condition, which if not detected and corrected, could result in the rudder deflection not being limited at high airplane speed, which, if combined with a large rudder pedal input, could lead to the loss of control of 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 2025-0004. (h) Exceptions to EASA AD 2025-0004 (1) Where EASA AD 2025-0004 refers to its effective date, this AD requires using the effective date of this AD. (2) Paragraph (1) of EASA AD 2025-0004 applies to all airplanes except for airplanes identified in paragraph (4) of EASA AD 2025-0004. (3) Where paragraph (3) of EASA AD 2025-0004 specifies "as required by paragraph (2) of this AD", this AD requires replacing that text with "as required by paragraphs (2) and (4) of this AD". (4) Where paragraph (4) of EASA AD 2025-0004 specifies "the additional work", this AD requires replacing that text with "the functional test of the rudder Travel Limiter Unit". (5) This AD does not adopt the "Remarks" section of EASA AD 2025-0004. (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.
