The FAA amends § 39.13 by adding the following new airworthiness directive: 2026-20-02 The Boeing Company: Amendment 39-23475; Docket No. FAA-2026-11785; Project Identifier AD-2026-00916-T.

(c) Applicability This AD applies to The Boeing Company Model 787-8 and 787-9 airplanes, certificated in any category, equipped with Rolls-Royce Deutschland Ltd & Co KG Model Trent 1000-A, Trent 1000-A2, Trent 1000-AE, Trent 1000-AE2, Trent 1000-C, Trent 1000-C2, Trent 1000-CE, Trent 1000-CE2, Trent 1000-D, Trent 1000-D2, Trent 1000-E, Trent 1000-G, Trent 1000-G2, Trent 1000-H, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 engines. (d) Subject Air Transport Association (ATA) of America Code 75, Air. (e) Unsafe Condition This AD was prompted by a report that there is no data to substantiate engine operability, including compressor stability, relight capability, surge recovery, and inclement weather capability, when an airplane is dispatched under Master Minimum Equipment List (MMEL) item 75-33-01. The FAA is issuing this AD to address the risk of MMEL dispatch with an inoperative engine intermediate pressure bleed valve (IPBV) on one or both engines. The unsafe condition, if not addressed, could result in loss of engine thrust control and consequent loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Dispatch Prohibitions As of 60 days after the effective date of this AD: No person may dispatch an airplane under the operational procedures of the operator's minimum equipment list item corresponding to MMEL 75-33-01 ("Engine Intermediate Pressure (IP) Bleed Valves (RR)"). (h) 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.

If sending information directly to the manager of the certification office, send it to the attention of the person identified in paragraph (i) of this AD. Information may be emailed to: AMOC@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
