Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines

Resumen

The FAA is withdrawing an NPRM that published on September 15, 2025, that would have applied to all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines. The NPRM would have required removal from service of affected low-pressure compressor (LPC) blades and replacement with a serviceable part. Since the NPRM was issued, it was determined that additional LPC blades are affected by the unsafe condition and were not included in the service material, and the FAA is evaluating for further rulemaking action. Accordingly, during this evaluation, the NPRM is withdrawn.
