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).

Federal Register / Vol. 80, No. 205 / Friday, October 23, 2015 / Rules and Regulations 64315 

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. 

Other Related Service Information 

Technify Motors GmbH has also 

issued Technify Motors SB No. TM TAE 

000–0007, Revision 28, dated February 

5, 2015; Technify Motors Installation 

Manual No. IM–02–02, Issue 4, Revision 

2, dated January 30, 2015, with Chapter 

02–IM–13–02, section 13.8.16, Revision 

1, dated November 28, 2014; Technify 

Motors SB No. SB TMG 601–1007 P1, 

Revision 3, dated February 5, 2015; and 

Technify Motors SB No. SB TMG 651– 

1004 P1, Revision 2, dated February 5, 

2015. Diamond Aircraft Industries 

GmbH (DAI) has issued DAI Mandatory 

Service Bulletin (MSB) No. 42–109/1, 

dated February 4, 2015; and DAI MSB 

No. 42–007/16, dated February 4, 2015. 

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. 

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.

SUPPLEMENTARY INFORMATION: 

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 

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
