Applicability*9

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).

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

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.

Unsafe condition

This AD was prompted by service experience that demonstrated premature wear of the splined coupling on the fuel pump and subsequent manufacturer revision of the time limits manual (TLM) to incorporate revised life limits and updated mandatory inspection intervals, including replacement of the fuel pump splined coupling. The FAA is issuing this AD to prevent premature wear of the splined coupling on the fuel pump. The unsafe condition, if not addressed, could result in failure of the engine and loss of the airplane.

Affected ADs

This AD replaces AD 2013-05-13, Amendment 39-17385 (78 FR 17080, March 20, 2013).
