Turboshaft Engines Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: 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: tkelley on DSK3SPTVN1PROD with SUMMARY: VerDate Mar<15>2010 16:21 Jan 30, 2013 Jkt 229001 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 PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 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.

ACTION: Final rule. AGENCY: 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. FOR FURTHER INFORMATION CONTACT: Scott Enander, Central Service Center, Operations Support Group, Federal Aviation Administration, Southwest Region, 2601 Meacham Blvd., Fort Worth, TX 76137; telephone 817–321– 7716. SUMMARY: 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 PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 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 E:\FR\FM\31JAR1.SGM 31JAR1

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 low-
pressure 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.
