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 <a href="http://www.regulations.gov">http://www.regulations.gov</a> 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
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.
