Airworthiness Directive · Amendment 39-22867 · Engine
Rolls-Royce Deutschland Ltd & Co KG Engines
This AD applies to Rolls-Royce Deutschland Ltd & Co KG Model Trent XWB-97 engines.
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent XWB-97 engines. This AD was prompted by the manufacturer revising the existing engine time limits manual (TLM) to introduce new or more restrictive instructions and associated thresholds and intervals for life-limited parts. This AD requires revising the airworthiness limitations section (ALS) of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive instructions and associated thresholds and intervals for life-limited parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). 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 AD 2024-0065, dated March 8, 2024 (EASA AD 2024-0065).
(1) Where EASA AD 2024-0065 refers to its effective date, this AD requires using the effective date of this AD.
(2) This AD does not require compliance with paragraphs (1), (2), (4), and (5) of EASA AD 2024-0065.
(3) Where paragraph (3) of EASA AD 2024-0065 specifies “Within 12 months after the effective date of this AD, revise the approved AMP,” replace that text with “Within 30 days after the effective date of this AD, revise the airworthiness limitation section (ALS) of the existing approved engine maintenance or inspection program, as applicable.”
(4) The initial compliance time for performing the tasks specified in paragraph (3) of EASA AD 2024-0065 is on or before the applicable “limitations” and “associated thresholds” as incorporated by the requirements of paragraph (3) of EASA AD 2024-0065, or within 30 days after the effective date of this AD, whichever occurs later.
(5) This AD does not adopt the “Remarks” paragraph of EASA AD 2024-0065.
After performing the actions required by paragraph (g) of this AD, no alternative actions and associated thresholds and intervals, including life limits, are allowed unless they are approved as specified in the “Ref. Publications” section of EASA AD 2024-0065.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
