FAA proposes rule to replace cracked engine blades on Rolls-Royce engines

The Federal Aviation Administration is proposing a new airworthiness directive that would require airlines to remove and replace certain engine blades on Rolls-Royce Deutschland Ltd & Co KG engines. The proposal targets the low-pressure compressor (LPC) blades found in specific models of the RB211 Trent 700 series engines, including the 768-60, 772-60, 772B-60, and 772C-60.

Why it matters: While this is a safety measure, it affects a very small number of engines currently flying in the United States. The FAA estimates that only eight engines installed on U.S.-registered airplanes are subject to this rule. For most travelers, the impact will be negligible; for the few airlines operating these specific engines, it means additional maintenance costs and potential downtime while parts are replaced.

Who it affects

• Airlines and operators using Rolls-Royce RB211 Trent 768-60, 772-60, 772B-60, and 772C-60 engines.
