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 2020-20-07, Amendment 39-21263 (85 FR 62975, October 6, 2020); and b. Adding the following new airworthiness directive: 2022-08-16 Rolls-Royce Deutschland Ltd & Co KG (Type Certificate previously held by Rolls-Royce plc): Amendment 39-22019; Docket No. FAA-2021-1164; Project Identifier MCAI-2021-00975-E. (a) Effective Date This airworthiness directive (AD) is effective May 31, 2022. (b) Affected ADs This AD replaces AD 2020-20-07, Amendment 39-21263 (85 FR 62975, October 6, 2020) (AD 2020-20-07). (c) Applicability This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) 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, Trent 1000-R3, Trent 7000-72, and Trent 7000-72C model turbofan engines installed as identified in European Union Aviation Safety Agency (EASA) AD 2019-0282R1, dated August 25, 2021 (EASA AD 2019-0282R1). (d) Subject Joint Aircraft Service Component (JASC) Code 7230, Turbine Engine Compressor Section. (e) Unsafe Condition This AD was prompted by a report of crack findings in the front air seal on the intermediate-pressure compressor (IPC) shaft assembly during the stripping of a flight test engine. The FAA is issuing this AD to prevent failure of the IPC shaft assembly. The unsafe condition, if not addressed, could result in loss of thrust control 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 2019-0282R1. (h) Exceptions to EASA AD 2019-0282R1 (1) Where EASA AD 2019-0282R1 requires compliance from November 27, 2019, the effective date of EASA AD 2019-0282, this AD requires compliance from November 10, 2020, the effective date of FAA AD 2020-20-07. (2) Where EASA AD 2019-0282R1 requires contacting Rolls-Royce for approved corrective actions if a crack is detected during any on-wing inspection and in-shop inspection, this AD requires removing the IPC shaft assembly and replacing it with a part eligible for installation before further flight. (3) Where EASA AD 2019-0282R1 defines a serviceable part as an IPC shaft assembly which is not an affected part; or an affected part which is new (never previously installed on an engine); or an affected part that, before (re)installation, has passed (no crack detected) an inspection in accordance with the instructions of the NMSB, this AD also includes in that definition an IPC shaft assembly that, before (re)installation, has passed a visual inspection (no crack detected) of the exposed part using FAA-approved maintenance procedures. (4) Where EASA AD 2019-0282R1 references on-wing inspections, this AD allows for a visual inspection of the IPC shaft assembly using FAA-approved maintenance procedures as a substitute for any on-wing borescope inspection if the affected part is exposed, provided that the compliance times specified in this AD are not exceeded. (5) This AD does not mandate compliance with the "Remarks" section of EASA AD 2019-0282R1. (i) Alternative Methods of Compliance (AMOCs) (1) The Manager, ECO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
