The FAA's summary their words, unchanged

The FAA is superseding Airworthiness Directive (AD) 2020-24- 08, which applied to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211 Trent 768-60, 772-60, 772B-60, and 772C-60 engines. AD 2020-24-08 required replacement of high-pressure turbine (HPT) blades with parts eligible for installation before exceeding specified flight cycles since new. Since the FAA issued AD 2020-24-08, RRD published updated service material to revise the applicability for certain engines and introduce a terminating action for the repetitive replacements of the HPT blades. This AD requires removal from service of certain engines and replacement of the HPT blades before exceeding specified flight cycles since new. This AD also allows for a modification of the engine that would eliminate the need for the repetitive replacements of the HPT blades. 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 2020-24-08, Amendment 39-21338 (85 FR 82302, December 18, 2020); and b. Adding the following new airworthiness directive: 2026-10-06 Rolls-Royce Deutschland Ltd & Co KG: Amendment 39-23346; Docket No. FAA-2026-4635; Project Identifier MCAI-2025-00213-E. (a) Effective Date This airworthiness directive (AD) is effective June 12, 2026. (b) Affected ADs This AD replaces AD 2020-24-08, Amendment 39-21338 (85 FR 82302, December 18, 2020). (c) Applicability This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines as identified in European Union Aviation Safety Agency (EASA) 2018-0291R1, dated February 24, 2025 (EASA AD 2018-0291R1). (d) Subject Joint Aircraft System Component (JASC) Code 7250, Turbine Section. (e) Unsafe Condition This AD was prompted by a manufacturer determination that high-pressure turbine (HPT) blades on certain RRD Model RB211 Trent 700 engines have been subject to high levels of corrosion fatigue. The FAA is issuing this AD to prevent failure of the HPT blades. The unsafe condition, if not addressed, could result in blade failure with increased risk of high-energy debris release, which could result in damage to the airplane 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) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, EASA AD 2018-0291R1.
