Rolls-Royce Deutschland Ltd & Co KG Engines
This AD applies to all Rolls-Royce Deutschland Ltd & Co KG Model RB211 Trent 768-60, 772-60, and 772B-60 engines.
The FAA is adopting 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 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 AD requires removal from service of the affected LPC blades and replacement with a serviceable part. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, European Union Aviation Safety Agency AD 2025-0288R1, dated June 26, 2026 (EASA AD 2025-0288R1).
(1) Where EASA AD 2025-0288R1 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2025-0288R1 refers to July 22, 2024 (the effective date of EASA AD 2024-0130), this AD requires using the effective date of this AD.
(3) This AD does not adopt the “Remarks” paragraph of EASA AD 2025-0288R1.
