Airworthiness Directive · Amendment 39-22575 · Turbine engine compressor section
Rolls-Royce Deutschland Ltd & Co KG 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, RB211-524H-36, RB211-524H-T-36, RB211-524H2-19, and RB211-524H2-T-19 engines.
The FAA is superseding Airworthiness Directive (AD) 2013-26-10 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211- 524G2-19, RB211-524G3-19, RB211-524H-36, and RB211-524H2-19 engines. AD 2013-26-10 required a one-time reduction in the cyclic life of certain high-pressure compressor (HPC) rotor stage 1 and stage 2 disks, and removal of disks that exceed the reduced cycle life. Since the FAA issued AD 2013-26-10, the manufacturer has revised the engine time limits manual (TLM), introducing new and more restrictive instructions. This AD is prompted by the manufacturer revising the engine time limits manual, introducing new and more restrictive instructions. This AD requires revisions to the airworthiness limitations section (ALS) of the operator's existing approved engine maintenance or inspection program, as applicable, 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 2022-0232, dated November 28, 2022 (EASA AD 2022-0232).
(1) Where EASA AD 2022-0232 defines the AMP as the “approved Aircraft Maintenance Programme which contains the tasks on the basis of which the scheduled maintenance is conducted to ensure the continuing airworthiness of each operated engine,” replace that text with the “Aircraft Maintenance Program which contains the tasks of which the operator or the owner ensures the continuing airworthiness of each operated airplane.”
(2) Where EASA AD 2022-0232 refers to its effective date, this AD requires using the effective date of this AD.
(3) This AD does not require compliance with paragraph (1) of EASA AD 2022-0232.
(4) This AD does not require compliance with paragraph (2) of EASA AD 2022-0232.
(5) Where paragraph (3) of EASA AD 2022-0232 specifies revising the approved Aircraft Maintenance Programme within 12 months after the effective date of EASA AD 2022-0232, this AD requires revising the airworthiness limitations section (ALS) of the existing approved engine maintenance or inspection program, as applicable, within 90 days after the effective date of this AD.
(6) This AD does not require compliance with paragraph (4) of EASA AD 2022-0232.
(7) This AD does not require compliance with paragraph (5) of EASA AD 2022-0232.
(8) This AD does not adopt the Remarks paragraph of EASA AD 2022-0232.
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 provisions of the “Ref. Publications” section of EASA AD 2022-0232.
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.
