Federal Aviation Administration 

14 CFR Part 39 

[Docket No. FAA–2013–0342; Directorate 

Identifier 2013–NE–14–AD; Amendment 39– 

17750; AD 2014–03–16]

Airworthiness Directives; Rolls-Royce 

Deutschland Ltd & Co. KG Turbofan 

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Rolls-Royce Deutschland Ltd & Co. KG 

(RRD) Tay 620–15, 650–15, and 651–54 

turbofan engines. This AD requires 

replacement of low-pressure compressor 

(LPC) fan blades. This AD was 

prompted by the discovery that the LPC 

fan blades leading edges erode in 

service and create an unacceptable 

blade flutter margin. We are issuing this 

AD to prevent LPC fan blade failure, 

damage to the engine, and damage to the 

airplane. 

DATES: This AD becomes effective 

March 18, 2014. 

ADDRESSES: The Docket Operations 

office is located at Docket Management 

Facility, U.S. Department of 

Transportation, 1200 New Jersey 

Avenue SE., West Building Ground 

Floor, Room W12–140, Washington, DC 

20590–0001.

SUPPLEMENTARY 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 specified products. The 

NPRM was published in the Federal 

Register on September 26, 2013 (78 FR 

59291). The NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Service history of Tay series engines 

discovered that low pressure compressor 

(LPC) fan blade leading edge is exposed to 

excessive deterioration. The LPC fan blade 

leading edge profile influences the LPC 

aerodynamic characteristics and stability. 

This condition, if not corrected, could reduce 

fan flutter margin and, in some cases, could 

lead to fan blade failure, possibly resulting in 

uncontained release of high energy debris 

with consequent damage to, and/or reduced 

control of, the aeroplane. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov/

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comment received. The 

commenter supports the NPRM (78 FR 

59291, September 26, 2013). 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

We estimate that this AD will affect 

about 52 engines of U.S. registry. We 

also estimate that it will take about six 

hours per product to comply with this 

AD. The average labor rate is $85 per 

hour. Required parts will cost about 

$11,000 per engine. Based on these 

figures, we estimate the cost of this AD 

on U.S. operators to be $598,520. 

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 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: 

(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.

Amendment to the International Traffic 

in Arms Regulations: Changes to 

Authorized Officials and the UK 

Defense Trade Treaty Exemption; 

Correction of Errors in Lebanon Policy 

and Violations; and Adoption of 

Recent Amendments as Final 

AGENCY: Department of State. 

ACTION: Final rule. 

SUMMARY: The Department of State is 

amending the International Traffic in 

Arms Regulations (ITAR) to remove the 

managing director as an authorized 

official, update the marking and 

reporting requirements for the UK 

defense treaty exemption, correct a 

typographical error in the paragraph on 

export policy regarding Lebanon, and 

correct an error of syntactical 

arrangement in a section of the 

regulations regarding violations. The 

Department is also adopting as a final 

rule certain sections of the ITAR that 

were published in an interim final rule. 

DATES: Effective Date: This rule is 

effective February 11, 2014. 

FOR FURTHER INFORMATION CONTACT: Mr. 

C. Edward Peartree, Director, Office of

Regulatory Change, Removing Managing 

Director, Other Changes. 

SUPPLEMENTARY INFORMATION: The 

Department is removing ‘‘Managing 

Director of Defense Trade Controls’’ as 

an authorized official from ITAR 

§ 120.1(b)(1) because it is no longer a 

position within the Department. Various 

sections of the ITAR are amended as a 

result. In each of these instances, 

another authorized official as identified 

in ITAR § 120.1(b) replaces the 

managing director. 

The Department is updating the text 

of the licensing exemption created 

pursuant to the Treaty Between the 

Government of the United States of 

America and the Government of the 

United Kingdom Concerning Defense 

Trade Cooperation (the ‘‘UK defense 

trade treaty exemption’’), at ITAR 

§ 126.17, so that it is a clearer 

representation of treaty requirements 

and is also consistent with ITAR 

§ 126.16 (the Australia defense trade 

treaty exemption). Most of the updates
