Airworthiness Directive · Amendment 39-22280 · Accessory gearboxes
Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
This AD applies to Rolls-Royce Deutschland Ltd & Co KG BR700-710A1-10, BR700-710A2-20, BR700-710C4-11, and BR700-710D5-21 model turbofan engines as identified in European Union Aviation Safety Agency (EASA) AD 2022-0033, dated March 03, 2022 (EASA AD 2022-0033).
The FAA is superseding Airworthiness Directive (AD) 2013-05-13 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-710 series turbofan engines. AD 2013-05-13 required replacing the affected fuel pump splined couplings. Since the FAA issued AD 2013-05-13, the manufacturer has revised the time limits manual (TLM), introducing new and more restrictive instructions, including the replacement of the fuel pump splined coupling. This AD is prompted by service experience that demonstrated premature wear of the splined coupling on the fuel pump and subsequent manufacturer revision of the TLM to incorporate revised life limits and updated mandatory inspection intervals, including replacement of the fuel pump splined coupling. This AD expands the applicability by adding a model turbofan engine and also requires revisions to the airworthiness limitations section (ALS) of the operator's existing approved aircraft maintenance program (AMP), 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 paragraphs (h) and (i) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, EASA AD 2022-0033.
(1) Where EASA AD 2022-0033 defines the AMP as the approved Aircraft Maintenance Programme on the basis of which the operator or the owner ensures the continuing airworthiness of each operated engine, this AD defines the AMP as the Aircraft Maintenance Program on the basis of which the operator or the owner ensures the continuing airworthiness of each operated airplane.
(2) Where EASA AD 2022-0033 refers to the effective date of EASA AD 2022-0033, this AD requires using the effective date of this AD.
(3) This AD does not require compliance with paragraph (1.2) of EASA AD 2022-0033.
(4) This AD does not require compliance with paragraph (2) of EASA AD 2022-0033.
(5) Where paragraph (3) of EASA AD 2022-0033 specifies revising the approved AMP within 12 months after its effective date, this AD requires incorporating the actions and associated thresholds and intervals, including life limits and maintenance tasks, into the existing approved maintenance or inspection program, as applicable, within 30 days of the initial replacement of the fuel pump splined coupling or within 90 days after the effective date of this AD, whichever comes later.
(6) This AD does not require compliance with paragraph (4) of EASA AD 2022-0033.
(7) This AD does not require compliance with paragraph (5) of EASA AD 2022-0033.
(8) This AD does not adopt the Remarks paragraph of EASA AD 2022-0033.
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 2022-0033.
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.
