Airworthiness Directive · Amendment 39-21872 · Engine
Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
Superseded. A later AD replaced this one: AD 2023-12-21. Comply with the one in force.
This AD applies to Rolls-Royce Deutschland Ltd & Co KG (Type Certificate previously held by Rolls-Royce plc) (RRD) Trent 1000-A2, Trent 1000-AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 model turbofan engines.
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000-A2, Trent 1000- AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 model turbofan engines. This AD was prompted by the manufacturer revising the engine Time Limits Manual (TLM) life limits of certain critical rotating parts, updating direct accumulation counting (DAC) data files, and updating certain maintenance tasks. This AD requires revision of the engine TLM life limits of certain critical rotating parts and DAC data files, 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 AD 2020-0241, dated November 5, 2020 (EASA AD 2020-0241).
(1) The requirements specified in paragraphs (1) and (2) of EASA AD 2020-0241 are not required by this AD.
(2) Where EASA AD 2020-0241 requires compliance from its effective date, this AD requires using the effective date of this AD.
(3) Paragraph (3) of EASA AD 2020-0241 specifies revising the approved airworthiness maintenance program within 12 months after its effective date, but this AD requires revising the existing approved continuous airworthiness maintenance program within 90 days after the effective date of this AD.
(4) This AD does not mandate compliance with the “Remarks” section of EASA AD 2020-0241.
Although the service information referenced in EASA AD 2020-0241 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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.
