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.

Compliance

Comply with this AD within the compliance times specified, unless already done.

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, European Union Aviation Safety Agency (EASA) AD 2021-0217, dated September 23, 2021 (EASA AD 2021-0217).

Unsafe condition

This AD was prompted by the manufacturer revising the time limits manual (TLM) to incorporate revised life limits and updated mandatory inspection intervals of certain critical rotating parts. The FAA is issuing this AD to prevent the failure of critical rotating parts. The unsafe condition, if not addressed, could result in failure of one or more engines, loss of thrust control, and loss of the airplane.

Affected ADs

This AD replaces AD 2021-15-01, Amendment 39-21648 (86 FR 36487, July 12, 2021).
