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: 2026-16-08 Rolls-Royce Deutschland Ltd & Co KG: Amendment 39-23438; Docket No. FAA-2026-2294; Project Identifier MCAI-2025-00011-E. (a) Effective Date This airworthiness directive (AD) is effective September 18, 2026. (b) Affected ADs None. (c) Applicability This AD applies to all Rolls-Royce Deutschland Ltd & Co KG Model Trent 1000-A2, Trent 1000-AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 engines. (d) Subject Joint Aircraft System Component (JASC) Code 7200, Engine (Turbine/Turboprop); 7230, Turbine Engine Compressor Section. (e) Unsafe Condition This AD was prompted by reports of cracking of the intermediate pressure (IP) compressor variable inlet guide vanes (VIGVs) due to high-cycle fatigue propagation. The FAA is issuing this AD to detect and correct cracking of the IP compressor VIGVs. The unsafe condition, if not addressed, could result in release of fractured parts with a steady state surge, consequent uncommanded in-flight shutdown (IFSD) and, in the case of dual-engine IFSD, 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: Do all required actions within the compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2025-0002, dated January 7, 2025 (EASA AD 2025-0002). (h) Exceptions to EASA AD 2025-0002 (1) Where EASA AD 2025-0002 refers to its effective date, this AD requires using the effective date of this AD. (2) This AD does not adopt the "Remarks" section of EASA AD 2025-0002. (i) No Reporting Requirement Although the service material referenced in EASA AD 2025-0002 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.
