Airworthiness Directive · Amendment 39-22103 · Engine turbine/turboprop
Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
This AD applies to Rolls-Royce Deutschland Ltd & Co KG Trent XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and Trent XWB-97 model turbofan engines.
The FAA is superseding Airworthiness Directive (AD) 2021-15-01 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and Trent XWB-97 model turbofan engines. AD 2021-15-01 required revisions to the airworthiness limitations section (ALS) of the Rolls-Royce (RR) Trent XWB time limits manual (TLM) and the operator's existing approved aircraft maintenance program (AMP). Since the FAA issued AD 2021-15-01, the manufacturer has revised the TLM life limits and updated mandatory inspection intervals of certain critical rotating parts. This AD requires revisions to the ALS of the RR Trent XWB TLM and the operator's existing approved AMP, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2021-0217, dated September 23, 2021 (EASA AD 2021-0217).
(1) Where EASA AD 2021-0217 defines the AMP as the approved Aircraft Maintenance Programme on the basis of which the operator or the owner ensures the continuing airworthiness of each operated engine, this AD defines the AMP as the existing Aircraft Maintenance Program on the basis of which the operator or the owner ensures the continuing airworthiness of each operated airplane.
(2) Where EASA AD 2021-0217 requires revising the approved aircraft maintenance program (AMP) within 12 months after the effective date of EASA AD 2021-0217, this AD requires revising the existing approved AMP and airworthiness limitations section (ALS) within 120 days after the effective date of this AD.
(3) This AD does not require compliance with paragraph (1), Mandatory Inspections and Replacement of Life Limited Parts, of EASA AD 2021-0217.
(4) This AD does not require compliance with paragraph (2), Corrective Action(s), of EASA AD 2021-0217.

(7) This AD does not require compliance with the “Remarks” section of EASA AD 2021-0217.
