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 affected fuel feed pumps. This AD 
was prompted by reports of in-flight shutdowns on TAE 125-02 engines. 
We are issuing this AD to prevent failure of the fuel feed pump, damage 
to the engine, and damage to the airplane.

DATES: This AD becomes effective May 9, 2016.

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 January 4, 2016 (81 FR 
27). 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

[[Page 19025]]

investigations showed that a defective fuel feed pump was the 
probable cause of the engine failure.

    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-2015-5193.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (81 FR 27, January 4, 
2016).

Conclusion

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

Related Service Information

    Technify Motors GmbH has issued Operation & Maintenance Manual, CD-
135/CD-155, OM-02-02, Issue 4, Revision No. 5, dated September 18, 
2015. The service information describes procedures for removing and 
replacing the fuel feed pump.

Costs of Compliance

    We estimate that this AD affects 190 engines installed on airplanes 
of U.S. registry. We also estimate that it will take about 0.5 hours 
per engine to comply with this AD. The average labor rate is $85 per 
hour. Pro-rated cost of the life limit reduction is about $160 per 
part. Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $38,475.

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

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2016-07-19 Technify Motors GmbH (Type Certificate previously held by 
Thielert Aircraft Engines GmbH): Amendment 39-18464; Docket No. FAA-
2015-5193; Directorate Identifier 2015-NE-35-AD.

(a) Effective Date

    This AD becomes effective May 9, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Technify Motors GmbH TAE 125-02-99 and 
TAE 125-02-114 reciprocating engines with a fuel feed pump, part 
number (P/N) 05-7312-K0073xx, or P/N 05-7312-K0133xx, where ``xx'' 
can be any number, installed.

(d) Reason

    This AD was prompted by reports of in-flight shutdowns on TAE 
125-02 engines. We are issuing this AD to prevent failure of the 
fuel feed pump, damage to the engine, and damage to the airplane.

(e) Actions and Compliance

    Comply with this AD within the compliance times specified, 
unless already done. Remove from service each affected fuel feed 
pump before it exceeds 600 operating hours (OH) time in service 
(TIS) or within 110 OH after the effective date of this AD, 
whichever occurs later.

(f) Installation Prohibition

    After the effective date of this AD, do not install onto any 
engine, any fuel feed pump, P/N 05-7312-K0073xx or P/N 05-7312-
K0133xx, where ``xx'' can be any number, if the fuel feed pump has 
600 hours or more TIS. If TIS of a fuel feed pump is unknown or has 
exceeded 600 hours TIS, then the fuel feed pump is not eligible for 
installation. Rebuilt, overhauled, or repaired fuel feed pumps or 
fuel feed pumps that lack a serial number, are not eligible for 
installation.
