Federal Register published on April 11, 2000 (65 FR 19477–78). 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. wreier-aviles on DSK5TPTVN1PROD with List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

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 September 13, 2012 (77 FR 56585). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Several cases of uncommanded in-flight shut-down (IFSD) have been reported on ARRIEL 1 engines. Results of subsequent investigations showed that some Gas Generator (GG) rear bearing failures have occurred following ‘‘Level 3’’ maintenance actions on the GG rotating assembly. Some of these maintenance actions may have created an unbalanced condition of the GG rotating assembly and, ultimately, failure of the GG rear bearing. This condition, if not detected and corrected, could lead to an uncommanded engine in-flight shut down and may ultimately lead to an emergency landing. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (77 FR 56585, September 13, 2012).

SUPPLEMENTARY INFORMATION: SUMMARY: wreier-aviles on DSK5TPTVN1PROD with History On September 6, 2012, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to establish V–629 near Las Vegas, NV. (77 FR 54859). Interested parties were invited to participate in this rulemaking effort by submitting written comments on this proposal to the FAA. No comments were received. The Rule The FAA is amending Title 14, Code of Federal Regulations (14 CFR) part 71 VerDate Mar<15>2010 12:02 Jan 09, 2013 Jkt 229001 by establishing VOR Federal airway V– 629, near Las Vegas, NV, to supplement the existing route structure and provide positive course guidance for aircraft navigating in an area of marginal radar coverage. VOR Federal airways are published in paragraph 6010(a) of FAA Order 7400.9W signed August 8, 2012 and effective September 15, 2012, which is incorporated by reference in 14 CFR 71.1. The VOR Federal airway listed in this document will be published subsequently in the Order. 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 Department of Transportation (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 United States Code. 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. 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 the 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 establishes a VOR Federal airway to enhance the safety and efficiency of the National Airspace System in the vicinity of Las Vegas, NV. Except for editorial changes, this rulemaking is the same as published in the NPRM. Environmental Review The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1E, Environmental Impacts: Policies and Procedures, paragraph 311a. This airspace action is not expected to cause any potentially PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.

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 September 13, 2012 
(77 FR 56585). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    Several cases of uncommanded in-flight shut-down (IFSD) have 
been reported on ARRIEL 1 engines. Results of subsequent 
investigations showed that some Gas Generator (GG) rear bearing 
failures have occurred following ``Level 3'' maintenance actions on 
the GG rotating assembly. Some of these maintenance actions may have 
created an unbalanced condition of the GG rotating assembly and, 
ultimately, failure of the GG rear bearing.

    This condition, if not detected and corrected, could lead to an 
uncommanded engine in-flight shut down and may ultimately lead to an 
emergency landing.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 56585, September 
13, 2012).

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed (77 FR 56585, 
September 13, 2012).

Costs of Compliance

    Based on the service information, we estimate that this AD affects 
about 1,445 engines installed on airplanes of U.S. registry. We also 
estimate that it will take about 1 hour per product to comply with this 
AD. The average labor rate is $85 per hour. Based on these figures, we 
estimate the cost of the AD on U.S. operators to be $122,825.

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.
