AD Amdt-39-23201

52560 Federal Register / Vol. 90, No. 223 / Friday, November 21, 2025 / Rules and Regulations 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES ■ 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] ■ 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2025–23–10 Rolls-Royce Deutschland Ltd & Co KG: Amendment 39–23194; Docket No. FAA–2025–4003; Project Identifier MCAI–2025–01205–E. (a) Effective Date This airworthiness directive (AD) is effective December 8, 2025. (b) Affected ADs None. (c) Applicability This AD applies to all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 1000–A, Trent 1000–AE, Trent 1000–C, Trent 1000–CE, Trent 1000–D, Trent 1000–E, Trent 1000–G, Trent 1000–H, Trent 1000–A2, Trent 1000–AE2, Trent 1000–C2, Trent 1000–CE2, Trent 1000–D2, Trent 1000–E2, Trent 1000– G2, Trent 1000–H2, Trent 1000–J2, Trent 1000–K2, and Trent 1000–L2 engines. (d) Subject Joint Aircraft System Component (JASC) Code 7230, Turbine Engine Compressor Section. (e) Unsafe Condition This AD was prompted by an investigation which revealed that certain low-pressure compressor (LPC) fan blades are at risk of cracking due to incorrect dressing. The FAA is issuing this AD to detect and correct cracking of the LPC fan blades. The unsafe condition, if not addressed, could result in fan blade failure and release of uncontained high-energy debris with consequent engine in-flight shut-down, which could result in damage to, and reduced control of, the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Except as specified in paragraph (h) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2025–0143, dated July 08, 2025 (EASA AD 2025–0143).

52561 Federal Register / Vol. 90, No. 223 / Friday, November 21, 2025 / Rules and Regulations ACTION : Final rule; removal; request for comments. SUMMARY : The FAA is removing Airworthiness Directive (AD) 2025–05– 14, which applied to all Airbus SAS Model A350–941 and –1041 airplanes. AD 2025–05–14 required repetitively testing the pre-cooler exchanger (PCE) for air leaks and reporting the results, and, depending on findings, inspecting the thermal blankets for damage and replacing the PCE. The FAA issued AD 2025–05–14 to address PCE leaking air, which could result in thermal blanket damage that, if combined with an independent event of engine fire, could lead to a temporary uncontrolled fire. Since the FAA issued AD 2025–05–14, a risk re-assessment has shown that the airworthiness concern is not an unsafe condition that warrants an AD. Accordingly, AD 2025–05–14 is removed. DATES : This AD becomes effective November 21, 2025. The FAA must receive comments on this AD by January 5, 2026. ADDRESSES : You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to regulations.gov. Follow the instructions for submitting comments. • Fax: 202–493–2251. • Mail: U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE, Washington, DC 20590. • Hand Delivery: Deliver to Mail address above between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA–2025–5029; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this final rule, the mandatory continuing airworthiness information (MCAI), any comments received, and other information. The street address for Docket Operations is listed above.

SUPPLEMENTARY INFORMATION : Comments Invited The FAA invites you to send any written data, views, or arguments about this final rule. Send your comments using a method listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2025–5029; Project Identifier MCAI–2024–00153–T’’ at the beginning of your comments. The most helpful comments reference a specific portion of the final rule, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule. Confidential Business Information CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this AD contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this AD, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ‘‘PROPIN.’’ The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this AD. Submissions containing CBI should be sent to Tak Kobayashi, Aviation Safety Engineer, FAA, 2200 South 216th St., Des Moines, WA 98198; phone: 206–231–3553; email: takahisa.kobayashi@faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. SUPPLEMENTARY INFORMATION : Background The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, previously issued EASA AD 2024–0058R2, dated October 4, 2024 (EASA AD 2024–0058R2), to correct an unsafe condition on all Airbus SAS Model A350–941 and –1041 airplanes. The FAA issued corresponding AD 2025–05–14, Amendment 39–22986 (90 FR 12449, March 18, 2025); corrected April 1, 2025 (90 FR 14331) (AD 2025–05–14), for those airplanes, as an interim AD. AD 2025–05–14 required repetitively testing the PCE for air leaks and reporting the results, and, depending on findings, inspecting the thermal blankets for damage and replacing the PCE. AD 2025–05–14 was prompted by a report indicating that the thrust reverser and pylon thermal blankets were found damaged due to air leaking from the PCE. The FAA issued AD 2025–05–14 to address PCE leaking air, which could result in thermal blanket damage that, if combined with an independent event of an engine fire, could lead to a temporary uncontrolled fire. Actions Since AD 2025–05–14 Was Issued Since the FAA issued AD 2025–05– 14, EASA issued AD 2024–0058R2–CN, dated August 20, 2025 (EASA AD 2024– 0058R2–CN), to cancel EASA AD 2024– 0058R2. EASA AD 2024–0058R2–CN states that further investigations confirmed that the fire barrier function of the inner fixed structure remained effective, and that the observed PCE air leakages are not impacting the fire detection/extinguishing capability. Consequently, the subsequent risk re- assessment has determined that the safety issue addressed by EASA AD 2024–0058R2 does not qualify as an unsafe condition. FAA’s Conclusions Upon further consideration, the FAA has determined that AD 2025–05–14 is no longer appropriate. Accordingly, this AD removes AD 2025–05–14. Removal of AD 2025–05–14 does not preclude the FAA from issuing another related action or commit the FAA to any course of action in the future. This AD removes all actions of AD 2025–05–14. Therefore, this AD terminates all requirements of AD 2025–05–14. 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. The actions required by interim AD 2025–05–14 are unnecessary because further investigations and the subsequent risk re-assessment have VerDate Sep<11>2014 16:20 Nov 20, 2025 Jkt 268001 PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 E:\FR\FM\21NOR1.SGM 21NOR1 khammond on DSK9W7S144PROD with RULES

52562 Federal Register / Vol. 90, No. 223 / Friday, November 21, 2025 / Rules and Regulations shown that the airworthiness concern addressed by that AD is not an unsafe condition that warrants an AD. Accordingly, notice and opportunity for prior public comment are unnecessary pursuant to 5 U.S.C. 553(b). In addition, for the foregoing reason, 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. Regulatory Flexibility Act (RFA) The requirements of the Regulatory Flexibility Act (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 FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required. Related Costs of Compliance This AD adds no costs. This AD removes AD 2025–05–14 from 14 CFR part 39; therefore, operators are no longer required to show compliance with that AD. 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. Regulatory Findings The FAA determined that 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.
