Proposed rule

Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines

Built by the Tribune's code from the Federal Register. No AI wrote this page. Published in the Federal Register May 20, 2026. Document 2026-10076. Updated Nov. 11, 2026.

What it does

The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent7000-72 and Trent7000-72C engines. This proposed AD was prompted by reports of engine in-flight shut-downs (IFSDs) caused by the premature failure of certain parts. This proposed AD would prohibit the installation of certain lubrication/scavenge pumps unless certain installation criteria are met. The FAA is proposing this AD to address the unsafe condition on these products.
