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 July 8, 2015 (80 FR 38990). The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Cases of a broken gearbox drive shaft have been reported on aeroplanes equipped with TAE 125–02 engines that have a Dual Mass Flywheel installed. Investigations results showed a possible overload of the gearbox drive shaft during starting of the engine or during restarting of the engine in-flight. This condition, if not corrected, could lead to engine power loss during flight, possibly resulting in loss of control of the aeroplane. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 38990, July 8, 2015). E:\FR\FM\23OCR1.SGM 23OCR1 Federal Register / Vol. 80, No. 205 / Friday, October 23, 2015 / Rules and Regulations Conclusion We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed. Related Service Information Under 1 CFR Part 51 Technify Motors GmbH has issued Service Bulletin No. SB TMG 125–1018 P1, Revision 1, dated February 5, 2015. The service information describes procedures for installing a start phase monitoring system and associated specified software mapping on particular airplane models. 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 of this final rule.

The service information describes procedures for installing a start phase monitoring system and associated specified software mapping. Costs of Compliance We estimate that this AD affects 97 engines installed on airplanes of U.S. registry. We also estimate that it will take about 3 hours per engine to comply with this AD. The average labor rate is $85 per hour. For 13 of the engines, required parts cost about $285 per engine. For 84 of the engines, required parts cost about $206 per engine. Based on these figures, we estimate the cost of this AD on U.S. operators to be $45,744. mstockstill on DSK4VPTVN1PROD with RULES Authority for This Rulemaking 16:44 Oct 22, 2015 Jkt 238001 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

SUPPLEMENTARY INFORMATION: ADDRESSES: Authority for This Rulemaking 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 BILLING CODE 4910–13–P VerDate Sep<11>2014 DEPARTMENT OF TRANSPORTATION Jkt 238001 PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 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 removes Class E airspace at O’Neal Airport, Vincennes, IN. History During an airspace review, the FAA found that O’Neal Airport, Vincennes, IN, has been abandoned since in 2009, therefore, controlled airspace is removed from the area. Since this eliminates the impact of controlled airspace on users of the National Airspace System, notice and public procedure under 553(b) are unnecessary. Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9Z dated August 6, 2015, and effective September 15, 2014, 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 removes Class E airspace extending upward from 700 feet above the surface within a 7-mile radius of O’Neal Airport, Vincennes, IN. The airport has been abandoned; therefore, controlled airspace is no longer necessary. 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 E:\FR\FM\23OCR1.SGM 23OCR1

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 July 8, 2015 (80 FR 
38990). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Cases of a broken gearbox drive shaft have been reported on 
aeroplanes equipped with TAE 125-02 engines that have a Dual Mass 
Flywheel installed.
    Investigations results showed a possible overload of the gearbox 
drive shaft during starting of the engine or during restarting of 
the engine in-flight.
    This condition, if not corrected, could lead to engine power 
loss during flight, possibly resulting in loss of control of the 
aeroplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 38990, July 8, 
2015).

[[Page 64315]]

Conclusion

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

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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2015-21-01 Technify Motors GmbH (Type Certificate Previously Held by 
Thielert Aircraft Engines GmbH): Amendment 39-18293; Docket No. FAA-
2015-1383; Directorate Identifier 2015-NE-15-AD.

(a) Effective Date

    This AD becomes effective November 27, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Technify Motors GmbH TAE 125-02-99 
(commercial designation CD-135, formerly Centurion 2.0) and TAE 125-
02-114 (commercial designation CD-155, formerly Centurion 2.0S) 
reciprocating engines, with a dual mass flywheel installed.

(d) Reason

    This AD was prompted by reports of a gearbox drive shaft 
breaking during starting or restarting of the engine. We are issuing 
this AD to prevent overload and failure of the gearbox drive shaft, 
which could lead to failure of the engine, in-flight shutdown, and 
loss of control of the airplane.

(e) Actions and Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    Within 110 flight hours or at the next scheduled inspection 
after the effective date of this AD, whichever occurs first, install 
a start phase monitoring system and software mapping. Use Technify 
Motors Service Bulletin (SB) No. SB TMG 125-1018 P1, Revision 1, 
dated February 5, 2015, to do the installation.

(f) Installation Prohibition

    After the effective date of this AD, do not install onto any 
airplane any Technify Motors TAE 125-02-99 or TAE 125-02-114 
reciprocating engine that is not equipped with a start phase 
monitoring system and software mapping.

(g) Alternative Methods of Compliance (AMOCs)

    The Manager, Engine Certification Office, may approve AMOCs for 
this AD. Use the procedures found in 14 CFR 39.19 to make your
