The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive No. 2012-0161, dated August 24, 2012 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:
RRD has issued Alert Non-Modification Service Bulletin SB-BR700-72-A900509, Revision 3, dated August 2, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.
This product has been approved by EASA and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
We estimate that this proposed AD would affect about 1,040 engines installed on airplanes of U.S. registry. We also estimate that it would take about 6 work-hours per engine to comply with this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $1,035 per engine. Based on these figures, we estimate the cost of this proposed AD to U.S. operators to be $1,606,800.
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. “Subtitle VII: Aviation Programs,” describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in “Subtitle VII, Part A, Subpart III, Section 44701: General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on
We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify this proposed regulation:
1. Is not a “significant regulatory action” under Executive Order 12866;
2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
1. The authority citation for part 39 continues to read as follows:
49 U.S.C. 106(g), 40113, 44701.
2. The FAA amends § 39.13 by adding the following new AD:
We must receive comments by January 7, 2013.
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.
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.
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, within 250 hours TIS.
(ii) If the engine has less than 3,750 hours TIS, before reaching 4,000 hours TIS.
(2) If you replaced the engine fuel pump splined coupling before the 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.
After the effective date of this AD, do not approve for return to service any engine with a fuel pump with an affected splined coupling that has accumulated 4,000 hours TIS, or any airplane with an engine with an affected fuel pump splined coupling installed that has accumulated 4,000 hours TIS.
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.
