AD 2025-17-17 ACTIVE

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. This AD was prompted by a determination that a batch of main landing gear (MLG) aft pintle pins did not have nickel plating applied to the inner bore during manufacturing. This AD requires replacing affected parts with serviceable parts and also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.

Final rule; request for comments.

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: 2025-17-17 Airbus SAS: Amendment 39-23127; Docket No. FAA-2025-2268; Project Identifier MCAI-2025-01296-T. (a) Effective Date This airworthiness directive (AD) is effective September 17, 2025. (b) Affected ADs None. (c) Applicability This AD applies to all Airbus SAS Model airplanes specified in paragraphs (c)(1) through (4) of this AD, certificated in any category. (1) Model A318-111, -112, -121, and -122 airplanes. (2) Model A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, -153N, -171N, and -173N airplanes. (3) Model A320-211, -212, -214, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes. (4) Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -253NY, -271N, -271NX, -271NY, -272N, and -272NX airplanes. (d) Subject Air Transport Association (ATA) of America Code 32, Landing Gear. (e) Unsafe Condition This AD was prompted by a determination that a batch of main landing gear (MLG) aft pintle pins did not have nickel plating applied to the inner bore during manufacturing. The FAA is issuing this AD to address MLG aft pintle pins without nickel plating. The unsafe condition, if not corrected, could lead to the development of corrosion with potential crack initiation in the affected parts, possibly resulting in a MLG collapse, with consequent damage to the airplane and injury to occupants. (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, European Union Aviation Safety Agency (EASA) AD 2025-0167, dated July 30, 2025 (EASA AD 2025-0167). (h) Exceptions to EASA AD 2025-0167 (1) Where EASA AD 2025-0167 refers to its effective date, this AD requires using the effective date of this AD. (2) Where EASA AD 2025-0167 defines a serviceable part as "MLG Aft Pintle Pin eligible for installation in accordance with Airbus instructions, which is not an affected part", this AD requires replacing that text with "MLG Aft Pintle Pin eligible for installation, which is not an affected part". (3) Where paragraph (1) of EASA AD 2025-0167 specifies to replace an affected part "in accordance with the instructions of the AOT", this AD requires replacing that text with "in accordance with paragraphs 5.5 of the instructions of the AOT". (4) Where the definition of affected part in EASA AD 2025-0167 specifies "a serial number as listed in the Appendix 1 of the AOT, as defined in this AD", this AD requires replacing that text with "a serial number as listed in the Appendix 1 of Airbus AOT A32N036-25, dated July 23, 2025". (5) This AD does not adopt the "Remarks" section of EASA AD 2025-0167.

Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2025-0167, dated July 30, 2025 (EASA AD 2025-0167) (also referred to as the MCAI), to correct an unsafe condition for all Airbus SAS Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, -153N, -171N, and -173N airplanes; Model A320-211, -212, -214, -215, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes; Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -253NY, -271N, -271NX, -271NY, -272N, and -272NX airplanes. Model A320-215 airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability. The MCAI states that it was determined that a batch of MLG aft pintle pins having Part Number (P/N) D3215600500600 or P/N D3215303000800 did not have nickel plating applied to the inner bore during manufacturing. The unsafe condition, if not corrected, could lead to the development of corrosion with potential crack initiation in the affected parts, possibly resulting in a MLG collapse, with consequent damage to the airplane and injury to occupants. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2025-2268. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed EASA AD 2025-0167, which specifies procedures to replace affected MLG pintle pins having Part Number P/N D3215600500600 or P/N D3215303000800 with a serviceable part. EASA AD 2025-0167 also prohibits the installation of affected parts. This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA's Determination These products have been approved by the civil aviation authority of another country and are approved for operation in the United States. Pursuant to the FAA's bilateral agreement with this State of Design Authority, that authority has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA is issuing this AD after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Requirements of This AD This AD requires accomplishing the actions specified in EASA AD 2025-0167 described previously, except for any differences identified as exceptions in the regulatory text of this AD. Explanation of Required Compliance Information In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, EASA AD 2025-0167 is incorporated by reference in this AD. This AD requires compliance with EASA AD 2025-0167 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Using common terms that are the same as the heading of a particular section in EASA AD 2025-0167 does not mean that operators need comply only with that section. For example, where the AD requirement refers to "all required actions and compliance times," compliance with this AD requirement is not limited to the section titled "Required Action(s) and Compliance Time(s)" in EASA AD 2025-0167. Material required by EASA AD 2025-0167 for compliance will be available at regulations.gov under Docket No. FAA-2025-2268 after this AD is published. Justification for Immediate Adoption and Determination of the Effective Date Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq. ) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for "good cause," finds that those procedures are "impracticable, unnecessary, or contrary to the public interest." Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies forgoing notice and comment prior to adoption of this rule because MLG aft pintle pins that do not have nickel plating applied to the inner bore could lead to the development of corrosion with potential crack initiation in the affected parts, possibly resulting in a MLG collapse, consequent damage to the airplane and injury to occupants. Additionally, the compliance time in this AD is shorter than the time necessary for the public to comment and for publication of the final rule. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b). In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forgo notice and comment. Regulatory Flexibility Act (RFA) The requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 1,945 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: Estimated Costs for Required Actions Labor cost Parts cost Cost per product Cost on U.S. operators 35 work-hours × $85 per hour = $2,975 $14,000 $16,975 $305,550 (Up to 18 airplanes *). * Only airplanes with affected parts must do the replacement. There are only 18 affected parts. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority. The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a "significant regulatory action" under Executive Order 12866, and (2) Will not affect intrastate aviation in Alaska.
