Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
The comment period closed Oct 1, 2026.
The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent XWB-75, XWB-79, XWB-79B, and XWB-84 engines. This proposed AD was prompted by reports of differential oil pressure measurements that were lower than expected on in-service engines. This proposed AD would require modification of the engine with an improved front bearing housing
