Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
§ 01 Summary
The FAA proposes a new airworthiness directive for Rolls-Royce Deutschland RB211 Trent 768-60, 772-60, and 772B-60 engines. The proposal would require operators to remove affected low-pressure compressor blades that underwent a non-conforming repair and replace them with serviceable parts.
§ 02 Why this matters
If finalized, the AD would create a mandatory maintenance obligation to remove specific non-conforming LPC blades from service and replace them with serviceable parts. The obligation is tied to an identified unsafe condition involving increased cracking risk in affected Rolls-Royce Trent engine blades.

Type: Proposed Rule Agencies: Transportation Department; Federal Aviation Administration Citation: 91 FR 32364 Title: Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines Abstract: 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.
