Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2014-0179; Directorate Identifier 2014-NE-03-AD; 
Amendment 39-17956; AD 2014-17-03]
RIN 2120-AA64


Airworthiness Directives; Technify Motors GmbH Reciprocating 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Technify Motors GmbH (type certificate previously held by Thielert 
Aircraft Engines GmbH) TAE 125-02-99 and TAE 125-02-114 reciprocating 
engines. This AD requires removal of each high-pressure (HP) fuel pump 
before 300 flight hours (FHs) in service or within 55 FHs after the 
effective date of the AD, whichever occurs later. This AD was prompted 
by in-flight shutdowns on airplanes with TAE 125-02 engines. We are 
issuing this AD to prevent failure of the HP fuel pump, which could 
result in damage to the engine and damage to the airplane.

DATES: This AD becomes effective October 2, 2014.

ADDRESSES: For service information identified in this AD, contact 
Technify Motors GmbH, Platanenstrasse 14, D-09356 Sankt Egidien, 
Germany, phone: +49-37204-696-0; fax: +49-37204-696-55; email:

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 May 23, 2014 (79 FR 
29693). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    In-flight shut down occurrences have been reported on aeroplanes 
equipped with TAE 125-02 engines. The initial results of the 
investigations showed that abnormal high wear of the high pressure 
fuel pumps was the probable cause of the engine failure.
    This condition, if not corrected, could result in further cases 
of engine power loss events and consequent potential 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 (79 FR 29693, May 23, 
2014).

Conclusion

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

Costs of Compliance

    We estimate that this AD affects 160 engines installed on airplanes 
of U.S. registry. We also estimate that it will take about 1 hour per 
engine 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 $13,600.

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

    After the effective date of this AD, do not install a TAE 125-
02-99 or TAE 125-02-114 engine with HP fuel pump, P/N 05-7312-
K005301 or P/N 05-7312-K005302, onto any airplane.
