The FAA's summary their words, unchanged

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.

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: a. Removing Airworthiness Directive 2024-25-10, Amendment 39-22912 (90 FR 8661, January 31, 2025); and b. Adding the following new airworthiness directive: 2026-13-06 Rolls-Royce Deutschland Ltd & Co KG: Amendment 39-23388; Docket No. FAA-2026-4661; Project Identifier MCAI-2025-01530-E. (a) Effective Date This airworthiness directive (AD) is effective July 17, 2026. (b) Affected ADs This AD replaces AD 2024-25-10, Amendment 39-22912 (90 FR 8661, January 31, 2025) (AD 2024-25-10). (c) Applicability This AD applies to certain Rolls-Royce Deutschland Ltd & Co KG Model Trent XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and Trent XWB-97 engines, as identified in European Union Aviation Safety Agency (EASA) AD 2025-0128R1, dated June 17, 2025 (EASA AD 2025-0128R1). (d) Subject Joint Aircraft System Component (JASC) Code 7200, Engine (Turbine/Turboprop); 7310, Engine Fuel Distribution. (e) Unsafe Condition This AD was prompted by a report of damage to the main fuel hose assembly of the fuel manifold, which led to a controlled, temporary engine fire and heat damage to the exterior and interior of the engine nacelle (thrust reverser C-ducts), and resulted in a commanded in-flight engine shut down. The FAA is issuing this AD to prevent damage to the main fuel hose assembly of the fuel manifold. The unsafe condition, if not addressed, in combination with additional failures, could lead to an engine fire and result in damage to the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Except as specified in paragraphs (h) and (i) of this AD: Do all required actions within the compliance times specified in, and in accordance with, EASA AD 2025-0128R1.

(7) Where EASA AD 2025-0128R1 states "engine flying hours (EFH)", this AD requires replacing that text with "engine flight hours (EFH)". (8) Where EASA AD 2025-0128R1 states "engine flying cycles (EFC)", this AD requires replacing that text with "engine flight cycles (EFC)". (9) This AD does not adopt the "Remarks" paragraph of EASA AD 2025-0128R1.
