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


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 
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 proposed AD was prompted by in-flight 
shutdowns on airplanes with TAE 125-02 engines. This proposed AD would 
require 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. We are proposing this AD to prevent failure 
of the HP fuel pump, which could result in damage to the engine and 
damage to the airplane.

DATES: We must receive comments on this proposed AD by July 22, 2014.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov and follow the instructions for sending your 
comments electronically.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2013-0279, dated November 26, 2013 (referred to hereinafter as ``the 
MCAI''), 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.

    We are proposing this AD to prevent damage to the engine and damage 
to the aircraft. 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 it in Docket No. FAA-2014-0179.

Relevant Service Information

    Technify Motors GmbH has issued Service Bulletin No. TM TAE 125-
1017 P1, Revision 1, dated September 20, 2013. The service information 
describes procedures for removing and replacing the HP fuel pump.

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 removal of each 
affected HP fuel pump.

Costs of Compliance

    We estimate that this proposed AD affects 160 engines installed on 
airplanes of U.S. registry. We also estimate that it would take about 1 
hour per engine to comply with this proposed AD. The average labor rate 
is $85 per hour. Based on these figures, we estimate the cost of the 
proposed 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

[[Page 29694]]

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.

later.

(f) Installation Prohibition

    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.
