Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines 

AGENCY: Federal Aviation Administration (FAA), DOT. 

ACTION: Fina l rule. 

SUMMARY: We are adopting a new airworthiness directive (AD) for a ll Rolls-Royce 

Deutschland Ltd & Co KG (RRD) BR700-725A 1-12 turbofan engines. This AD requires 

removal of affected fuel metering units (FMUs) on RRD BR700-725A 1- 12 engines. This 

AD was prompted by reports of wear on the receptors of the double-ended unions in the 

FMU housing on BR700-725A 1-12 engines causing fuel leakage. We are issuing this AD 

to prevent failure of the FMU, which could lead to damage to one or more engines and 

damage to the airplane. 

OAT ES: This AD becomes effective [INSERT DATE 35 DAYS AFTER DATE OF 

PUBLICATION IN THE FEDERAL REGISTER].

SU PPLEM ENTARY INFORMATION: 

Discussion 

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by 

adding an AD that would apply to the specilied products. The NPRM was published in 

the Federal Register on February 14, 20 14 (79 FR 8905 ). The N PRM proposed to corTect 

an unsafe condition for the specified products. The MCAI states: 

2 
Comments 

We gave the public the opportunity to participate in developing this AD. We 

received no comments on the NPRM (79 FR 8905, February 14, 20 14 ). 

Conclusion 

We reviewed the available data and determined that air safety and the public 

interest require adopting this AD as proposed. 

Costs of Compliance 

We estimate that this AD affects 24 RRD turbofan engines installed on aircraft of 

U.S. registry. We also estimate that it would take about 6 hours per engine to comply 

with this AD. The average labor rate is $85 per hour. Required parts cost about $293,960 

per engine. Based on these figures, we estimate the cost of this AD on U.S. operators to 

be $7,067,280. 

Authority for This Rulemaking 

Title 49 of the United States Code specifies the FAA's authority to issue rules on 

aviation safety. Subtitle I, section I 06, describes the authority of the FAA Administrator. 

··subtitle Vll: Aviation Programs," describes in more detail the scope of the Agency's 

authority. 

We are issuing this rulemaking under the authority described in "Subtitle VTT, 

Part A, Subpart Ill, Section 4470 I: General requirements." Under that section, Congress 

3 
identified in this rulemaking action. 

Regulatory Findings 

We determined that this AD will not have federalism implications under 

Executive Order 13132. This AD will 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 AD: 

(I) Is not a "significant regulatory action" under Executive Order 12866, 

(2) Is not a "significant rule" under the DOT Regulatory Policies and Procedures 

(44 f'R II 034, February 26, 1979), 

(3) Will not affect intrastate aviation in Alaska to the extent that it justifies 

making a regulatory distinction, and 

(4) 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.

(g) Definition 

For the purpose of this AD, an f'MU eligible for install ation is a new FMU or an 

FMU with P/N G3000FMU03 that has accumulated fewer than 650 FHs since install ation
