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 March 1, 2016 (81 FR 10544). The NPRM proposed to correct E:\FR\FM\31MYR1.SGM 31MYR1 34266 Federal Register / Vol. 81, No. 104 / Tuesday, May 31, 2016 / Rules and Regulations an unsafe condition for the specified products. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2016– 0009, dated January 13, 2016 (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Some cases of divergent rubbing between the piston shaft small diameter labyrinth and the rear bearing support have been reported. This condition, if not corrected, could lead to an uncommanded engine in-flight shutdown. You may obtain further information by examining the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2016– 2859. Regulatory Findings Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (81 FR 10544, March 1, 2016). Conclusion We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed. asabaliauskas on DSK3SPTVN1PROD with RULES Related Service Information Turbomeca S.A. has issued Mandatory Service Bulletin (MSB) No. 292 72 1357, Version B, dated November 12, 2015. The MSB describes procedures for installing a postmodification (mod) TU357 gas generator module (M03). This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance We estimate that this proposed AD affects 426 engines installed on helicopters of U.S. registry. We also estimate that it would take about 40 hours per engine to comply with this proposed AD. The average labor rate is $85 per hour. Required parts cost about $16,500 per engine. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $8,477,400. 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 VerDate Sep<11>2014 16:39 May 27, 2016 Jkt 238001 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. 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.

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 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 controlled airspace at Lisbon Municipal Airport, Lisbon, ND. History On February 17, 2016, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to establish Class E Airspace in the Lisbon, ND area. (81 FR 8026) Docket No. FAA–2015–5800. 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 7400.9Z dated August 6, 2015, and effective September 15, 2015, 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. Availability and Summary of Documents for Incorporation by Reference This document amends FAA Order 7400.9Z, airspace Designations and Reporting Points, dated August 6, 2015, and effective September 15, 2015. FAA Order 7400.9Z is publicly available as listed in the ADDRESSES section of this document. FAA Order 7400.9Z lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points. The Rule This amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 establishes Class E airspace extending upward from 700 feet above the surface within a 6.5-mile radius of Lisbon Municipal Airport, Lisbon, ND, to accommodate new RNAV standard instrument approach procedures. Controlled airspace is needed for the PO 00000 Frm 00027 Fmt 4700 Sfmt 4700 34267 safety and management of IFR operations at the airport. Class E airspace designations are published in Paragraph 6005 of FAA Order 7400.9Z, dated August 6, 2015, and effective September 15, 2015, 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. Regulatory Notices and Analyses 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, is non-controversial and unlikely to result in adverse or negative comments. It, therefore: (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 only affects air traffic procedures and air navigation, it is certified that this rule, when promulgated, does not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. Environmental Review The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1F, ‘‘Environmental Impacts: Policies and Procedures,’’ paragraph 5–6.5. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exists that warrant preparation of an environmental assessment.

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 1D and 1D1 turboshaft engines with a pre-
modification (mod) TU357 gas generator module (M03), installed. This AD 
requires removing the pre-modification (mod) TU357 gas generator module 
(M03) and replacing with a part eligible for installation. This AD was 
prompted by reports of divergent rubbing between the piston shaft small 
diameter labyrinth and the rear bearing support. We are issuing this AD 
to prevent failure of the labyrinth seal and engine, in-flight 
shutdown, and loss of control of the helicopter.

DATES: This AD becomes effective July 5, 2016.

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 March 1, 2016 (81 FR 
10544). The NPRM proposed to correct

[[Page 34266]]

an unsafe condition for the specified products.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2016-0009, dated January 13, 2016 (referred to hereinafter as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    Some cases of divergent rubbing between the piston shaft small 
diameter labyrinth and the rear bearing support have been reported.
    This condition, if not corrected, could lead to an uncommanded 
engine in-flight shutdown.

    You may obtain further information by examining the MCAI in the AD 
docket on the Internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2016-2859.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (81 FR 10544, March 1, 
2016).

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed.

Related Service Information

    Turbomeca S.A. has issued Mandatory Service Bulletin (MSB) No. 292 
72 1357, Version B, dated November 12, 2015. The MSB describes 
procedures for installing a post-modification (mod) TU357 gas generator 
module (M03). This service information is reasonably available because 
the interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this proposed AD affects 426 engines installed on 
helicopters of U.S. registry. We also estimate that it would take about 
40 hours per engine to comply with this proposed AD. The average labor 
rate is $85 per hour. Required parts cost about $16,500 per engine. 
Based on these figures, we estimate the cost of this proposed AD on 
U.S. operators to be $8,477,400.

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 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.
