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 June 1, 2026. Document 2026-10902. Updated Nov. 10, 2026.

What it does

The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines. This proposed AD was prompted by a report that a batch of low-pressure compressor (LPC) blades were exposed to a non-conforming repair and are more prone to cracking due to a deviation from the approved blade configuration design. This proposed AD would require removal from service of the affected LPC blades and replacement with a serviceable part. The FAA is proposing this AD to address the unsafe condition on these products.
