What the agency says
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.
