Description

The FAA is superseding Airworthiness Directive (AD) 2024-25-10 for certain Rolls-Royce Deutschland Ltd & Co KG Model Trent XWB-97 engines. The directive requires visual and dimensional inspections of the main fuel hose assembly of the fuel manifold to check for softness, compliance, resistance, shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire, with replacement if necessary. The new AD expands applicability to include additional engine models and requires repetitive inspections for some engines. It also provides criteria for installation of affected parts and optional terminating actions for inspections to address an unsafe condition that could lead to engine fire and damage to the airplane.
