2013-05-13: Fuel pump splined couplings

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2013-05-13 Rolls-Royce Deutschland Ltd & Co KG (Formerly Rolls-Royce Deutschland GmbH, and BMW Rolls-Royce plc): Amendment 39-17385; Docket No. FAA-2012-1100; Directorate Identifier 2012-NE-29-AD. (a) Effective Date This airworthiness directive (AD) becomes effective April 24, 2013. (b) Affected ADs None. (c) Applicability This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-710A1-10 and BR700-710A2-20 turbofan engines, all serial numbers, and BR700-710C4-11 turbofan engines that have either of the following hardware configuration standards engraved on the engine data plate: (1) Standard ``710C4-11''--RRD Alert Non-Modification Service Bulletin (NMSB) SB-BR700-72-101466 standard not incorporated, or (2) Standard ``710C4-11/10''--RRD Alert NMSB SB-BR700-72-101466 standard incorporated. (d) Reason This AD was prompted by service experience that demonstrated premature wear of the splined coupling on the fuel pump. We are issuing this AD to prevent failure of the engine and loss of the airplane. (e) Actions and Compliance Unless already done, do the following. (1) After the effective date of this AD, replace the fuel pump splined coupling as follows and every 4,000 hours time in service (TIS) thereafter: (i) If the engine has 3,750 hours TIS or more on the effective date of this AD, within 250 hours TIS. (ii) If the engine has less than 3,750 hours TIS on the effective date of this AD, before reaching 4,000 hours TIS. (2) If you replaced the engine fuel pump splined coupling beforethe effective date of this AD, replace the fuel pump splined coupling before reaching 4,000 hours TIS since last replacement, or before further flight, whichever comes later. (f) Installation Prohibition After the effective date of this AD, do not install into any engine a fuel pump with an affected splined coupling that has accumulated 4,000 hours TIS, or install any engine with an affected splined coupling that has accumulated 4,000 hours TIS onto an airplane. (g) Alternative Methods of Compliance (AMOCs) The Manager, Engine Certification Office, FAA, may approve AMOCs to this AD. Use the procedures found in 14 CFR 39.19 to make your request.
