FAA Proposes Fix for Oil Pressure Issues in Rolls-Royce Trent XWB Engines

Table of Contents
The Federal Aviation Administration (FAA) has proposed a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent XWB-75, XWB-79, XWB-79B, and XWB-84 engines. This proposal is a response to reports that some in-service engines showed differential oil pressure measurements lower than expected.
Why it matters: This is a standard safety maintenance action. The practical significance is that airlines operating these specific engine models will likely need to schedule work to replace a specific part to ensure oil pressure remains within expected ranges. It does not change how the planes fly or who can fly them, but it does add a maintenance requirement to keep the engines running safely.
Who it affects
- Airlines operating aircraft equipped with Rolls-Royce Trent XWB-75, -79, -79B, or -84 engines
