[FR Doc. 2026–13372 Filed 7–1–26; 8:45 am] BILLING CODE 3410–90–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2026–4661; Project Identifier MCAI–2025–01530–E; Amendment 39–23388; AD 2026–13–06] RIN 2120–AA64 Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines AGENCY : Federal Aviation Administration (FAA), DOT. ACTION : Final rule; request for comments. SUMMARY : The FAA is superseding Airworthiness Directive (AD) 2024–25– 10, which applied to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent XWB–97 engines. AD 2024–25–10 required a one-time set of visual and dimensional inspections of the main fuel hose assembly of the fuel manifold to confirm softness, compliance, and lack of resistance, and for shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire; and, if necessary, replacement of the main fuel hose assembly of the fuel manifold. Since the FAA issued AD 2024–25–10, the FAA has determined that additional engine models are affected by the unsafe condition and that the required inspections should be repetitive. This AD requires, for certain engines, a one-time set of on-wing visual and dimensional inspections of the main fuel hose assembly of the fuel manifold to confirm softness, compliance, and lack of resistance, and for shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire and, if necessary, replacement of the main fuel hose assembly of the fuel manifold. This AD also requires, for certain other engines, on-wing and in-shop repetitive visual and dimensional inspections of the main fuel hose assembly of the fuel manifold to confirm softness, compliance, and lack of resistance, and for shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire and, if necessary, replacement of the main fuel hose assembly of the fuel manifold. This AD also expands the applicability to include certain RRD Model Trent XWB– 75, Trent XWB–79, Trent XWB–79B, and Trent XWB–84 engines. This AD also provides criteria for installation of an affected part and optional terminating action for the repetitive visual and dimensional inspections. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD is effective July 17, 2026. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 17, 2026. The FAA must receive comments on this AD by August 17, 2026.

Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA issued AD 2024–25–10, Amendment 39–22912 (90 FR 8661, January 31, 2025) (AD 2024–25–10), for certain RRD Model Trent XWB–97 engines. AD 2024–25–10 was prompted by an emergency AD originated by EASA, which is the Technical Agent for the Member States of the European Union. EASA issued EASA Emergency AD 2024–0174–E, dated September 5, 2024 (EASA Emergency AD 2024–0174– E) to correct an unsafe condition identified as damage to the main fuel hose assembly of the fuel manifold. AD 2024–25–10 required a one-time set of visual and dimensional inspections of the main fuel hose assembly of the fuel manifold to confirm softness, compliance, and lack of resistance, and for shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire; and, if necessary, replacement of the main fuel hose assembly of the fuel manifold. The FAA issued AD 2024–25–10 to prevent damage to the main fuel hose assembly of the fuel manifold. Actions Since EASA Emergency AD 2024–0174–E Was Issued EASA superseded EASA Emergency AD 2024–0174–E and issued EASA AD 2024–0182, dated September 19, 2024 (later revised) (EASA AD 2024–0182); EASA AD 2024–0182R1, dated October 9, 2024 (superseded) (EASA AD 2024– 0182R1); EASA AD 2025–0128, dated June 3, 2025 (later revised) (EASA AD 2025–0128); and EASA AD 2025– 0128R1, dated June 17, 2025 (EASA AD 2025–0128R1) (also referred to as the MCAI). EASA AD 2024–0182 included new service material, specified that a certain cleaning process available during engine refurbishment may lead to degradation of the main fuel hose assembly of the fuel manifold, that additional engine model groups were affected by the unsafe condition, and that repetitive inspections were necessary. EASA AD 2024–0182R1 included a revision to the service material and clarified the terminating action for the repetitive inspections. EASA AD 2025–0128, included a revision to the service material and identified an additional population of engines affected by the unsafe condition and required repetitive inspections and corrective actions for those engines. The MCAI states that damage to a fuel manifold main fuel hose was reported, which led to a controlled, temporary engine fire and heat damage to the exterior and interior of the engine nacelle (thrust reverser C-ducts). The occurrence resulted in an in-flight shutdown. In-service and in-shop inspections identified a specific cleaning process available during engine refurbishment that may lead to degradation of the main fuel hose assembly of the fuel manifold. Additionally, multiple additional populations of affected engines were identified, and a determination was made that the initial population of affected engines could be reduced to exclude certain engine serial numbers. To address this potential unsafe condition, the manufacturer published service information that specifies procedures for a one-time set of visual and dimensional inspections of the fuel manifold main fuel hoses and corrective action instructions. This condition, if not addressed, in combination with additional failures, could lead to an engine fire and damage to the airplane. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2026–4661. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed EASA AD 2025– 0128R1, which specifies procedures for a one-time set of on-wing visual and dimensional inspections of the main fuel hose assembly of the fuel manifold to confirm softness, compliance, and lack of resistance, and for shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire and, if necessary, replacement of the main fuel hose assembly of the fuel manifold, and reporting the inspection results to RRD. EASA AD 2025–0128R1 also specifies procedures for on-wing and in-shop repetitive visual and dimensional inspections of the main fuel hose assembly of the fuel manifold to confirm softness, compliance, and lack of resistance, and for shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire and, if necessary, replacement of the main fuel hose assembly of the fuel manifold, and reporting the inspection results to RRD. EASA AD 2025–0128R1 also allows installation of an affected part on any airplane provided that the part is serviceable and allows installation of an affected engine provided that the engine passed the required inspections, or the findings were corrected. EASA AD 2025–0128R1 also includes optional terminating action for the repetitive visual and dimensional inspections provided that the engine has passed an inspection with no findings or the findings are corrected, or the engine has not yet reached the threshold of the required inspections. 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.

40355 Federal Register / Vol. 91, No. 126 / Thursday, July 2, 2026 / Rules and Regulations FAA’s Determination These products have been approved by the civil aviation authority (CAA) 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. AD Requirements This AD requires accomplishing the actions specified in EASA AD 2025– 0128R1, described previously, as incorporated by reference, 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 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 2025–0128R1 is incorporated by reference in this AD. This AD requires compliance with EASA AD 2025–0128R1 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 2025–0128R1 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 2025–0128R1. Material required by EASA AD 2025– 0128R1 for compliance will be available at regulations.gov under Docket No. FAA–2026–4661 after this AD is published. Interim Action The preamble to AD 2024–25–10 specifies that the FAA considers that AD to be an ‘‘interim action’’ and that the FAA might consider further rulemaking depending on the results of the investigation. The manufacturer has since developed such repetitive inspections and, if necessary, replacement of the main fuel hose assembly of the fuel manifold for certain engines, which is optional terminating action to the repetitive inspections required by AD 2024–25–10. The FAA has determined that these actions must be required to mitigate the unsafe condition. 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 FAA justifies waiving notice and comment prior to adoption of this rule because no domestic operators use this product. It is unlikely that the FAA will receive any adverse comments or useful information about this AD from any U.S. operator. Accordingly, notice and opportunity for prior public comment are unnecessary, pursuant to 5 U.S.C. 553(b). In addition, for the foregoing reason(s), 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 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. Costs of Compliance There are no costs of compliance with this AD because there are no engines with this type certificate on the U.S. Registry. 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.
