14 CFR Part 39 

[Docket No. FAA–2012–0940; Directorate 

Identifier 2012–NE–26–AD; Amendment 39– 

17321; AD 2013–01–07] 

RIN 2120–AA64 

Airworthiness Directives; Turbomeca 

S.A. Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

Turbomeca S.A. Arriel 2D turboshaft 

engines. This AD was prompted by a 

low fuel pressure event caused by 

deterioration and a loss of the lowpressure drive function within the 

hydro-mechanical metering unit (HMU). 

This AD requires replacing the HMU at 

a reduced life. We are issuing this AD 

to prevent an uncommanded in-flight 

shutdown of the engine, and possible 

loss of the helicopter. 

DATES: This AD becomes effective 

March 7, 2013. 

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 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on October 9, 2012 (77 FR 

61303). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information states: 

During an Arriel 2D endurance test, the 

illumination of the low fuel pressure warning 

light was observed. The investigation of the 

high pressure/low pressure (HP/LP) pump 

assembly within the hydro-mechanical 

metering unit (HMU), removed following this 

occurrence, revealed a deterioration and a 

loss of the LP pump drive function. 

This condition, if not detected and 

corrected, could lead to an uncommanded 

engine in-flight shut down. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (77 

FR 61303). 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

(77 FR 61303) as proposed. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD will affect about 

27 products of U.S. registry. We also 

estimate that it will take about 0.7 hour 

per engine to comply with this AD. The 

average labor rate is $85 per hour. 

Required parts will cost about $14,400 

per engine. Based on these figures, we 

estimate the cost of this AD on U.S. 

operators to be $390,407. 

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); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (phone: 

800–647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

replacement of the low-pressure pump 

spindle wheel assembly, high-pressure pump 

complete sleeve, bearings/pinions (matched 

assembly), and sleeve assembly.

Docket No. 11–AGL–30] 

Amendment of Class E Airspace; 

Ontonagon, MI 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action amends Class E 

airspace at Ontonagon, MI. Additional 

controlled airspace is necessary to 

accommodate new Area Navigation 

(RNAV) Standard Instrument Approach 

Procedures at Ontonagon County— 

Schuster Field Airport. Also, this action 

renames the airport. The FAA is taking 

this action to enhance the safety and 

management of Instrument Flight Rule 

(IFR) operations at the airport. 

DATES: Effective date: 0901 UTC, May 2, 

2013. The Director of the Federal 

Register approves this incorporation by 

reference action under 1 CFR Part 51, 

subject to the annual revision of FAA 

Order 7400.9 and publication of 

conforming amendments.

SUPPLEMENTARY INFORMATION: 

History 

On August 2, 2012, the FAA 

published in the Federal Register a 

notice of proposed rulemaking (NPRM) 

to amend Class E airspace for the 

Ontonagon, MI, area, creating additional 

controlled airspace at Ontonagon 

County—Schuster Field Airport (77 FR 

45984) Docket No. FAA–2011–1404. 

Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. No comments 

were received. Class E airspace 

designations are published in paragraph 

6005 of FAA Order 7400.9W dated 

August 8, 2012, and effective September 

15, 2012, which is incorporated by 

reference in 14 CFR 71.1. The Class E 

airspace designations listed in this 

document will be published 

subsequently in the Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) Part 71 by 

amending Class E airspace extending 

upward from 700 feet above the surface 

to accommodate new standard 

instrument approach procedures at 

Ontonagon County—Schuster Field 

Airport, Ontonagon, MI. This action is 

necessary for the safety and 

management of IFR operations at the 

airport. The airport name is also 

updated from Ontonagon County 

Airport to Ontonagon County—Schuster 

Field Airport to coincide with the 

FAA’s aeronautical database. 

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 

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) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. Since this is a 

routine matter that will only affect air 

traffic procedures and air navigation, it 

is certified that this rule, when 

promulgated, will not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act. 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the U.S. Code. Subtitle 1, 

Section 106, describes the authority of 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the agency’s 

authority. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it amends
