AD 2026-13-06: Rolls-Royce Deutschland Ltd & Co KG Engines

What the FAA requires

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.

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
