FAA Targets Cracking Blades in Trent Engines

Published Date: 6/1/2026

Proposed Rule

Summary

The FAA wants to make sure Rolls-Royce Deutschland RB211 Trent 768-60, 772-60, and 772B-60 engines stay safe by fixing a problem with some low-pressure compressor blades that might crack. They’re proposing to remove the faulty blades and replace them with good ones. If you own or operate these engines, you’ll need to act soon, and the FAA is asking for comments by July 16, 2026.

Analyzed Economic Effects

2 provisions identified: 1 benefits, 1 costs, 0 mixed.

Operators Must Replace Faulty LPC Blades

If you own or operate Rolls‑Royce RB211 Trent 768-60, 772-60, or 772B-60 engines, the FAA proposes you must remove affected low‑pressure compressor (LPC) blades and replace them with serviceable parts. The FAA estimates parts cost $225,000 plus 2 work‑hours at $85/hour ($170) per engine, for a total of $225,170 per engine and $1,801,360 for eight engines on U.S. registry.

Reduces Risk of Catastrophic Engine Failures

The rule targets LPC blades exposed to a non‑conforming repair that are prone to cracking. Removing and replacing those blades is intended to reduce the risk of in‑flight shutdown, engine fire, and uncontained high‑energy debris release on aircraft using these engines.
