71364 Federal Register / Vol. 79, No. 231 / Tuesday, December 2, 2014 / Proposed Rules 

MCAI and service information 

referenced above. We are proposing this 

NPRM 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 

implementation of a life limit for certain 

P/N LPT stage 3 turbine blades and 

replacement of affected blades that 

reach or exceed the life limit. 

Costs of Compliance 

We estimate that this proposed AD 

affects 2 engines installed on airplanes 

of U.S. registry. We also estimate that it 

would take about 120 hours per engine 

to comply with this proposed AD. The 

average labor rate is $85 per hour. Based 

on these figures, we estimate the cost of 

this proposed AD on U.S. operators to 

be $20,400. 

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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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. Amend § 39.13 by adding the 

following new airworthiness directive 

(AD): 

Rolls-Royce plc: Docket No. FAA–2014– 

0904; Directorate Identifier 2014–NE– 

14–AD. 

(a) Comments Due Date 

We must receive comments by February 2, 

2015. 

(b) Affected ADs 

None. 

(c) Applicability 

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

RB211–524B–02, RB211–524B–B–02, 

RB211–524B2–19, RB211–524B2–B–19, 

RB211–524B3–02, RB211–524C2–19, and 

RB211–524C2–B–19 turbofan engines with 

low-pressure turbine (LPT) stage 3 turbine 

blade, part number (P/N) LK55386, LK86483, 

or LK86503, installed. 

(d) Reason 

This AD was prompted by reports of LPT 

stage 3 turbine blade failure, release of 

blades, and subsequent in-flight shutdown. 

We are issuing this AD to prevent failure of 

LPT stage 3 turbine blades and subsequent 

release of blade debris, which could lead to 

failure of one or more engines, loss of thrust 

control, and damage to the airplane. 

(e) Actions and Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(1) Remove from service before further 

flight any LPT stage 3 turbine blade, P/N 

LK55386, LK86483, or LK86503, that exceeds 

11,000 flight cycles since new. 

(2) If you cannot determine the 

accumulated flight cycles, remove any LPT 

stage 3 turbine blade, P/N LK55386, 

LK86483, or LK86503 within 200 flight 

cycles after the effective date of this AD. 

(3) After the effective date of this AD, do 

not install any LPT stage 3 turbine blade, 

P/N LK55386, LK86483, or LK86503, on any 

engine if the blade has accumulated 11,000 

or more flight cycles since new. 

(f) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

FAA, may approve AMOCs for this AD. Use 

the procedures found in 14 CFR 39.19 to 

make your request. You may email your 

request to: ANE-AD-AMOC@faa.gov.

SUPPLEMENTARY INFORMATION: On 

December 20, 2013, a NPRM was 

published in the Federal Register (78 

FR 77023) to amend Title 14 Code of 

Federal Regulations (14 CFR) part 71 to 

establish Class E Airspace extending 

upward from 1,200 feet above the 

surface at the Tucumcari VHF OmniDirectional Radio Range Tactical Air 

Navigation Aid (VORTAC) Tucumcari, 

NM, to contain aircraft while in 

Instrument Flight Rules conditions 

under control of Albuquerque Air Route 

Traffic Control Center by vectoring 

aircraft from en route airspace to 

terminal areas. As a result of objections 

that were raised during the comment 

period, the NPRM is being withdrawn. 

A new NPRM will be forthcoming.

The Proposal 

This action proposes to amend title 

14, Code of Federal Regulations (14 

CFR), part 71 by establishing Class E 

airspace extending upward from 700 

feet above the surface within a 6.5-mile 

radius of Clark County Airport, Clark, 

SD, to accommodate new standard 

instrument approach procedures. 

Controlled airspace is needed for the 

safety and management of IFR 

operations at the airport. 

Class E airspace areas are published 

in Paragraph 6005 of FAA Order 

7400.9Y, dated August 6, 2014 and 

effective September 15, 2014, which is 

incorporated by reference in 14 CFR 

71.1. The Class E airspace designation 

listed in this document will be 

published subsequently in the Order.
