We propose to adopt a new airworthiness directive (AD) for all Technify Motors GmbH TAE 125-02 reciprocating engines with a dual mass flywheel installed. This proposed AD was prompted by reports of a gearbox drive shaft breaking during starting or restarting of the engine. This proposed AD would require installation of a start phase monitoring system and associated specified software. We are proposing 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.

Airworthiness Directives; Technify Motors GmbH Reciprocating 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Technify Motors GmbH TAE 125-02 reciprocating engines with a dual mass 
flywheel installed. This proposed AD was prompted by reports of a 
gearbox drive shaft breaking during starting or restarting of the 
engine. This proposed AD would require installation of a start phase 
monitoring system and associated specified software. We are proposing 
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.

DATES: We must receive comments on this proposed AD by September 8, 
2015.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2015-0055, dated March 31, 2015 (referred to hereinafter as ``the 
MCAI''), 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.

    You may obtain further information by examining the MCAI in the AD 
docket on the Internet at http://www.regulations.gov by searching for 
and locating Docket No. FAA-2015-1383.

Related Service Information Under 1 CFR Part 51

    Technify Motors GmbH (type certificate previously held by Thielert 
Aircraft Engines GmbH) issued Technify Motors Service Bulletin (SB) 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 NPRM.

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

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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of 
Germany, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the European Community, EASA has 
notified us of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all information provided by EASA and determined the unsafe 
condition exists and is likely to exist or develop on other products of 
the same type design. This proposed AD would require installation of 
specified software mapping and a start phase monitoring system.

Costs of Compliance

    We estimate that this proposed AD affects 97 engines installed on 
airplanes of U.S. registry. We also estimate that it would take about 3 
hours per engine to comply with this proposed 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 
proposed 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (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.

The Proposed Amendment

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