The FAA's summary their words, unchanged

The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG Model Trent 1000-AE3, Trent 1000- CE3, Trent 1000-D3, Trent 1000-G3, Trent 1000-H3, Trent 1000-J3, Trent 1000-K3, Trent 1000-L3, Trent 1000-M3, Trent 1000-N3, Trent 1000-P3, Trent 1000-Q3, Trent 1000-R3, Trent 7000-72, and Trent 7000-72C engines. This AD was prompted by reports of cracked intermediate pressure compressor (IPC) shaft assembly front air seals. This AD requires an inspection of the affected IPC shaft assembly for cracking and, depending on the results of the inspection, repetitive inspections or replacement of the IPC shaft assembly front air seals, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(f), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2025-02-14 Rolls-Royce Deutschland Ltd & Co KG: Amendment 39-22947; Docket No. FAA-2024-2414; Project Identifier MCAI-2024-00530-E. (a) Effective Date This airworthiness directive (AD) is effective April 1, 2025. (b) Affected ADs None. (c) Applicability This AD applies to Rolls-Royce Deutschland Ltd & Co KG Model Trent 1000-AE3, Trent 1000-CE3, Trent 1000-D3, Trent 1000-G3, Trent 1000-H3, Trent 1000-J3, Trent 1000-K3, Trent 1000-L3, Trent 1000-M3, Trent 1000-N3, Trent 1000-P3, Trent 1000-Q3, Trent 1000-R3, Trent 7000-72, and Trent 7000-72C engines. (d) Subject Joint Aircraft System Component (JASC) Code 7230, Turbine Engine Compressor Section. (e) Unsafe Condition This AD was prompted by reports of cracked intermediate pressure compressor (IPC) shaft assembly front air seals. The FAA is issuing this AD to prevent an IPC stage 1 disk burst or failure of the IPC front seal. The unsafe condition, if not addressed, could result in an IPC stage 1 disk burst with consequent release of high energy debris and damage to the airplane or failure of the IPC front seal and release of debris, which could lead to an engine in-flight shutdown (IFSD) and in the case of a dual IFSD could result in reduced control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Except as specified in paragraphs (h), and (i) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, European Union Aviation Safety Agency AD 2024-0178, dated September 12, 2024 (EASA AD 2024-0178).

(2) Where the service information referenced in EASA AD 2024-0178 specifies to reject the engine, this AD requires removing the affected part from service. (3) This AD does not adopt the Remarks paragraph of EASA AD 2024-0178. (i) No Reporting Requirement Although the service information referenced in EASA AD 2024-0178 specifies to submit certain information to the manufacturer, this AD does not include that requirement. (j) Alternative Methods of Compliance (AMOCs) (1) The Manager, AIR-520 Continued Operational Safety Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
