Rolls-Royce Deutschland Ltd & Co Engines
This AD applies to Rolls-Royce Deutschland Ltd & Co. KG (RRD) Model RB211-524G2-19, RB211-524G2-T-19, RB211-524G3-19, RB211-524G3-T-19, RB211-524H2-19, RB211-524H2-T-19, RB211-524H-36, and RB211-524H-T-36 engines.
The FAA is superseding Airworthiness Directive (AD) 2020-15-07 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) (type certificate previously held by Rolls-Royce plc) Model RB211-524G2-19, RB211-524G2- T-19, RB211-524G3-19, RB211-524G3-T-19, RB211-524H2-19, RB211-524H2-T- 19, RB211-524H-36, and RB211-524H-T-36 engines. AD 2020-15-07 required replacement of the low-pressure turbine (LPT) stage 1 disk with part number (P/N) UL37606, UL37607, UL37608, UL37722, or UL37790, installed. This AD was prompted by an updated analysis by the engine manufacturer, which indicates certain part-numbered and serial-numbered LPT stage 1 disks that have undergone rework could fail before the current published life limits. This AD retains the requirement to replace the LPT stage 1 disk and includes additional LPT stage 1 disks, 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 2022-0237, dated December 2, 2022 (EASA AD 2022-0237).
(1) Where EASA AD 2022-0237 refers to its effective date, this AD requires using the effective date of this AD.
(2) This AD does not adopt the “Remarks” section of EASA AD 2022-0237.
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.
