RIN 2120–AA64 

Airworthiness Directives; Rolls-Royce 

plc Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding 

airworthiness directive (AD) 98–07–07 

for all Rolls-Royce plc (RR) RB211– 

535E4 and RB211–535E4–B turbofan 

engines. AD 98–07–07 required 

removing certain part number (P/N) 

low-pressure (LP) fuel filter-to-highpressure (HP) fuel pump tube 

assemblies and installing flexible LP 

fuel filter-to-HP fuel pump tube 

assemblies. This AD expands the 

applicability of AD 98–07–07 to include 

the RB211–535E4–C–37 turbofan engine 

and requires removal from service of 

additional P/N LP fuel filter-to-highpressure HP fuel pump tube assemblies. 

This AD was prompted by reports of 

fuel leaks that have resulted in a 

number of engine in-flight shutdowns. 

We are issuing this AD to prevent loss 

of fuel supply to the engine, which 

could lead to an in-flight shutdown of 

one or more engines, loss of thrust 

control, and damage to the airplane. 

DATES: This AD is effective January 6, 

2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 98–07–07, 

Amendment 39–10426 (63 FR 18119, 

April 14, 1998), (‘‘AD 98–07–07’’). AD 

98–07–07 applied to the specified 

products. The NPRM published in the 

Federal Register on July 24, 2014 (79 FR 

42989). The NPRM proposed to expand 

the applicability of AD 98–07–07 to 

include the RB211–535E4–C–37 

turbofan engine and added two 

additional P/Ns identified for removal. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Support for the NPRM as Proposed 

United Airlines supports issuing the 

NPRM (79 FR 42989, July 24, 2014) as 

proposed. 

Request To Change the Compliance 

FedEx Express requested that the 

proposed AD require removal of only 

fuel tube assemblies, P/Ns 163521538 

and 163521545. These are the only fuel 

tube assemblies that are required to be 

removed by RR Service Bulletin No. 

RB.211–73–H131 and European 

Aviation Safety Agency AD 2014–0123. 

We do not agree. This AD will 

supersede AD 98–07–07. AD 98–07–07 

required the removal of fuel tube 

assemblies, P/Ns UL16692 and 

AE709623–1. Continuing to include 

these P/Ns would ensure, in the 

unlikely event that there is an engine 

containing fuel tube assemblies, P/Ns 

UL16692 and AE709623–1, that these 

fuel tube assemblies would still be 

removed. We did not change this AD. 

Change to the Compliance 

We changed paragraph (e)(2) of this 

AD to mandate installation of LP fuel 

filter-to-HP fuel pump tube assemblies 

eligible for installation. Paragraph (e)(2) 

was changed to support the Costs of 

Compliance as proposed in the NPRM 

(79 FR 42989, July 24, 2014). 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of 

this AD. 

Costs of Compliance 

We estimate that this AD affects 500 

engines installed on airplanes of U.S. 

registry. We also estimate that it will 

take about 7.33 hours per engine to 

comply with this AD. The average labor 

rate is $85 per hour. Required parts cost 

about $10,000 per engine. Based on 

these figures, we estimate the cost of 

this AD on U.S. operators to be 

$5,311,525. 

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 

This AD will not have federalism 

implications under Executive Order 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 79, No. 231 / Tuesday, December 2, 2014 / Rules and Regulations 71309 

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 that this AD: 

(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), 

(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.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends part 39 of the Federal 

Aviation Regulations (14 CFR part 39) as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing airworthiness directive (AD) 

98–07–07, Amendment 39–10426 (63 

FR 18119, April 14, 1998), and adding 

the following new AD: 

2014–24–08 Rolls-Royce plc: Amendment 

39–18041; Docket No. FAA–2014–0433; 

Directorate Identifier 94–ANE–39–AD. 

(a) Effective Date 

This AD is effective January 6, 2015. 

(b) Affected ADs 

This AD supersedes AD 98–07–07, 

Amendment 39–10426 (63 FR 18119, April 

14, 1998). 

(c) Applicability 

This AD applies to all Rolls-Royce plc (RR) 

RB211–535E4–37, RB211–535E4–B–37, and 

RB211–535E4–C–37 turbofan engines with 

low-pressure (LP) fuel filter-to-high-pressure 

(HP) fuel pump tube assembly, part number 

(P/N) UL16692, AE709623–1, 163521538, or 

163521545, installed. 

(d) Unsafe Condition 

This AD was prompted by reports of fuel 

leaks that have resulted in a number of 

engine in-flight shutdowns. We are issuing 

this AD to prevent loss of fuel supply to the 

engine, which could lead to an in-flight 

shutdown of one or more engines, loss of 

thrust control, and damage to the airplane. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(1) After the effective date of this AD, 

remove from service all LP fuel filter-to-HP 

fuel pump tube assemblies, P/Ns UL16692, 

AE709623–1, 163521538, and 163521545, at 

the next part removal or during the next 

engine shop visit, whichever occurs first. 

(2) Install LP fuel filter-to-HP fuel pump 

tube assemblies eligible for installation. 

(f) Definition 

For the purpose of this AD, an ‘‘engine 

shop visit’’ is the induction of an engine into 

the shop for maintenance. 

(g) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

may approve AMOCs for this AD. Use the

Amendment of Class D Airspace; 

MacDill AFB, FL 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; technical 

amendment. 

SUMMARY: This action amends Class D 

Airspace at MacDill AFB, FL, by adding

the annual revision of FAA Order 

7400.9 and publication of conforming 

amendments.

SUPPLEMENTARY INFORMATION: 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) Part 71 by 

clarifying in the airspace description the 

ceiling of the Class D airspace area at 

MacDill AFB, FL, adding the words ‘‘to 

but not including 1,200 feet MSL’’. This 

avoids any confusion with the floor of 

the overlying Tampa International 

Airport Class B airspace area, which is 

1,200 feet MSL. This is an 

administrative change and does not 

affect the boundaries, or operating 

requirements of the airspace, therefore, 

notice and public procedure under 5 

U.S.C. 553(b) are unnecessary. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation: (1) Is
