[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.
