The FAA's summary their words, unchanged

The FAA is superseding Airworthiness Directive (AD) 2023-26-04 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) 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, and Trent 1000-R3 engines. AD 2023-26-04 required initial and repetitive in-shop visual inspections of the intermediate-pressure stage 8 (IP8) and high-pressure stage 3 (HP3) air transfer tubes and front bearing housing IP8 air feed tubes for cracking, damage, or air leakage wear, and replacement, if necessary. Since the FAA issued AD 2023-26-04, the FAA has determined that a new set of initial and repetitive on-wing visual inspections of the IP8 and HP3 air transfer tubes for cracking, damage, or air leakage wear are necessary, and consequently the inspection interval for the repetitive in-shop visual inspections of front bearing housing IP8 air feed tubes may be increased. This AD requires initial and repetitive in-shop visual inspections of the IP8 and HP3 air transfer tubes and front bearing housing IP8 air feed tubes (with increased inspection interval) for cracking, damage, or air leakage wear, and replacement, if necessary. This AD also requires initial and repetitive on-wing visual inspections of the IP8 and HP3 air transfer 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: a. Removing Airworthiness Directive 2023-26-04, Amendment 39-22647 (89 FR 251, January 3, 2024); and b. Adding the following new airworthiness directive: 2026-10-21 Rolls-Royce Deutschland Ltd & Co KG: Amendment 39-23361; Docket No. FAA-2026-0742; Project Identifier MCAI-2025-01337-E. (a) Effective Date This airworthiness directive (AD) is effective July 9, 2026. (b) Affected ADs This AD replaces AD 2023-26-04, Amendment 39-22647 (89 FR 251, January 3, 2024). (c) Applicability This AD applies to 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, and Trent 1000-R3 engines. (d) Subject Joint Aircraft System Component (JASC) Code 7500, Engine Bleed Air System. (e) Unsafe Condition This AD was prompted by a determination that a new set of on-wing initial and repetitive visual inspections of the intermediate-pressure stage 8 (IP8) and high-pressure stage 3 (HP3) air transfer tubes for cracking, damage, or air leakage wear are necessary, and consequently the inspection interval for the repetitive in-shop visual inspections of the front bearing housing IP8 air feed tubes may be increased. The FAA is issuing this AD to prevent failure of the IP8 and HP3 air transfer tubes and front bearing housing IP8 air feed tubes. The unsafe condition, if not addressed, could affect the engine internal cooling and sealing flows, resulting in failure of the IP8 air transfer tubes, HP3 air transfer tubes, and front bearing housing IP8 air feed tubes, with consequent 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 paragraph (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 (EASA) AD 2025-0176, dated August 7, 2025 (EASA AD 2025-0176).
