The FAA's summary their words, unchanged

The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 7000-72 and Trent 7000-72C engines. This AD was prompted by the manufacturer's determination that certain intervals for visual inspection of the intermediate pressure 8 (IP8) and high pressure 3 (HP3) air tubes need to be reduced for certain engines, and instructions for visual inspection of the IP8 and HP3 air tubes were not available for certain other engines. This AD requires initial and repetitive visual inspections of the IP8 and HP3 air tubes for cracking, damage, or air leakage wear, and replacement if necessary. 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(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2026-04-13 Rolls-Royce Deutschland Ltd & Co KG: Amendment 39-23273; Docket No. FAA-2025-1730; Project Identifier MCAI-2023-01122-E. (a) Effective Date This airworthiness directive (AD) is effective April 10, 2026. (b) Affected ADs None. (c) Applicability This AD applies to all Rolls-Royce Deutschland Ltd & Co KG Model Trent 7000-72 and Trent 7000-72C engines. (d) Subject Joint Aircraft System Component (JASC) Code 7500, Engine Bleed Air System. (e) Unsafe Condition This AD was prompted by the manufacturer's determination that certain intervals for visual inspection of the intermediate pressure 8 (IP8) and high pressure 3 (HP3) air tubes need to be reduced for certain engines, and instructions for visual inspection of the IP8 and HP3 air tubes were not available for certain other engines. The FAA is issuing this AD to prevent failure of the IP8 and HP3 air tubes. The unsafe condition, if not addressed, could result in reduced efficiency of internal cooling and sealing flows, failure of the IP8 air tubes and HP3 air tubes, damage to the engine, and 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 2023-0186, dated October 27, 2023 (EASA AD 2023-0186). (h) Exceptions to EASA AD 2023-0186 (1) Where EASA AD 2023-0186 requires compliance from its effective date, this AD requires using the effective date of this AD. (2) Where paragraph (6) of EASA AD 2023-0186 states "any damage is detected", this AD requires replacing that text with "any cracking, damage, or sign of air leakage is detected". (3) This AD does not adopt the "Remarks" paragraph of EASA AD 2023-0186. (i) No Reporting Requirement Although the service material referenced in EASA AD 2023-0186 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.
