Description

The FAA proposes a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG Model RB211 Trent 768-60, 772-60, and 772B-60 engines. This AD is prompted by a report that a batch of low-pressure compressor (LPC) blades were exposed to a non-conforming repair, making them more prone to cracking due to deviation from the approved blade configuration design. The proposed AD requires removal from service of the affected LPC blades and replacement with serviceable parts to address the unsafe condition and prevent potential structural failures, in-flight shutdown, engine fire, and uncontained debris release. Comments on the proposal are due by July 16, 2026.
