Airworthiness Directive · Amendment 39-22546 · Turbine engine compressor section
Rolls-Royce Deutschland Ltd & Co KG Engines
This AD applies to Rolls-Royce Deutschland Ltd & Co KG Model RB211-535C-37 engines.
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-535C-37 engines. This AD is prompted by the manufacturer revising the existing engine time limits manual (TLM) to introduce new or more restrictive airworthiness limitations and associated thresholds and intervals for life-limited parts. This AD requires revising the airworthiness limitations section (ALS) of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive instructions and associated thresholds and intervals for life-limited parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). 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 2022-0236, dated December 1, 2022 (EASA AD 2022-0236).
(1) Where EASA AD 2022-0236 defines the AMP as the approved Aircraft Maintenance Programme containing the tasks on the basis of which the scheduled maintenance is conducted to ensure the continuing airworthiness of each operated engine, this AD defines the AMP as the aircraft maintenance program containing the tasks on the basis of which the scheduled maintenance is conducted to ensure the continuing airworthiness of each operated airplane.
(2) Where EASA AD 2022-0236 refers to its effective date, this AD requires using the effective date of this AD.
(3) This AD does not require compliance with paragraphs (1), (2), (4), and (5) of EASA AD 2022-0236.
(4) Where paragraph (3) of EASA AD 2022-0236 specifies revising the approved AMP within 12 months after the effective date of EASA AD 2022-0236, this AD requires revising the airworthiness limitations section of the existing approved engine maintenance or inspection program, as applicable, within 90 days after the effective date of this AD.
(5) This AD does not adopt the Remarks paragraph of EASA AD 2022-0236.
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 2022-0236.
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.
