Applicability*9

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.

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 2022-0237, dated December 2, 2022 (EASA AD 2022-0237).

Unsafe condition

This AD was prompted by an updated analysis by the engine manufacturer, which indicates certain part-numbered and serial-numbered low-pressure turbine (LPT) stage 1 disks that have undergone rework could fail before the current published life limits. The FAA is issuing this AD to prevent failure of the LPT stage 1 disk. The unsafe condition, if not addressed, could result in uncontained release of high-energy debris from the engine, in-flight shutdown of the engine, damage to the engine, and damage to the airplane.

Affected ADs

This AD replaces AD 2020-15-07, Amendment 39-21170 (85 FR 43682, July 20, 2020).
