Airworthiness Directives; Rolls-Royce 

plc Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Rolls-Royce plc (RR) RB211 Trent 768– 

60, 772–60, and 772B–60 turbofan 

engines. This proposed AD was 

prompted by fuel leaks caused by 

damage to the fan case low-pressure 

(LP) fuel tube. This proposed AD would 

require inspection of the fan case LP 

fuel tubes and associated clips and the 

fuel oil heat exchanger (FOHE) mounts 

and associated hardware. We are 

proposing this AD to prevent failure of 

the fan case LP fuel tube, which could 

lead to an in-flight shutdown of one or 

more engines due to fuel starvation, loss 

of thrust control, and damage to the 

airplane. 

DATES: We must receive comments on 

this proposed AD by September 2, 2014.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2014– 

0089, dated April 15, 2014 (referred to 

hereinafter as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Fuel leaks from the engine have occurred 

in-service due to damage to sections of the 

fan case low-pressure (LP) fuel tube which 

runs between the fuel oil heat exchanger 

(FOHE) and the high pressure fuel pump. 

Frettage damage between the securing clips 

and the tube outer surface has been caused 

by excessive movement within the system 

that resulted from deterioration of the FOHE 

mounting hardware. The thinning of the tube 

wall causes the tube to fracture and fuel loss 

to occur. 

This condition, if not detected and 

corrected, could lead to a critical fuel 

imbalance or in-flight fuel starvation, 

possibly resulting engine in-flight shut-down 

and, consequently, reduced control of the 

aeroplane. 

For the reasons described above, this AD 

requires repetitive on-wing and in-shop 

inspections and, depending on findings, 

replacement of fan case LP fuel tubes, clips 

and FOHE mounting hardware. 

You may obtain further information 

by examining the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2014– 

0363. 

Relevant Service Information 

RR has issued Alert Non-Modification 

Service Bulletin (NMSB) No. RB.211– 

73–AH522, Revision 1, dated March 18, 

2014. The Alert NMSB describes 

procedures for on-wing and in-shop 

inspection and replacement if 

necessary, of the LP fuel tubes and 

FOHE mounts and associated hardware. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of the United 

Kingdom 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. This 

proposed AD would require inspection 

of affected LP fuel tubes and FOHE 

mounts and associated hardware and, if 

necessary, replacement with a part 

eligible for installation. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 50 engines installed 

on airplanes of U.S. registry. We also 

estimate that it would take about 6 

hours per engine to comply with this 

proposed AD. The average labor rate is 

$85 per hour. Based on these figures, we 


ehiers on DSK2VPTVN1PROD with PROPOSALS
37966 Federal Register / Vol. 79, No. 128 / Thursday, July 3, 2014 / Proposed Rules 

estimate the cost of this proposed AD on 

U.S. operators to be $25,500. 

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 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 

products identified in this rulemaking 

action. 

Regulatory Findings 

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), 

(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.

(202) 267–9677, for a copy of Advisory 

Circular No. 11–2A, Notice of Proposed 

Rulemaking Distribution System, which 

describes the application procedure. 

The Proposal 

The FAA is proposing an amendment 

to Title 14 Code of Federal Regulations 

(14 CFR) Part 71 by modifying Class D 

airspace, Class E surface airspace and 

Class E airspace extending upward from 

700 feet above the surface at the TriCities Airport, Pasco, WA. After a 

biennial review of the airspace, the FAA 

found modification of the airspace 

necessary for the safety and 

management of aircraft departing and 

arriving under IFR operations at the 

airport. The Class D airspace area would 

be expanded from the existing 4.3 miles 

to 4.8 miles, west of the airport, from 

the 255° radial to the 12° radial and two 

segments extending 5.8 miles southwest 

and northeast of the airport would be 

added. The cutout of the Class D 

airspace for Vista Airport would be 

eliminated, as Vista Airport is closed. 

The Class E surface airspace would be 

adjusted to coincide with the 

dimensions of the Class D airspace. The 

Class E airspace designated as an 

extension to the Class D and Class E 

surface area would be removed as they 

are no longer needed for IFR operations. 

The Class E airspace extending 700 feet 

above the surface would be decreased to 

an 11 mile radius of the airport with 

segments extending from the 11 mile 

radius to 13 miles northeast and 

southeast of the airport and a segment 

4 miles south and 9 miles north of a 226 

degree bearing from the airport 

extending to 15 miles southwest of the 

airport. These actions are necessary to 

accommodate RNAV (GPS) standard 

instrument approach procedures and for 

the safety and management of IFR 

operations at the airport. 

Class D airspace and Class E airspace 

designations are published in paragraph 

5000, 6002, 6004 and 6005 respectively, 

of FAA Order 7400.9X, dated August 7, 

2013, and effective September 15, 2013, 

which is incorporated by reference in 14 

CFR 71.1. The Class D and Class E 

airspace designations listed in this 

document will be published 

subsequently in this Order. 

The FAA has determined this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. 

Therefore, this proposed regulation; (1) 

is not a ‘‘significant regulatory action’’ 

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under DOT 

Regulatory Policies and Procedures (44 

FR 11034; February 26, 1979); and (3)
