14 CFR Part 39
[Docket No. FAA-2013-0557; Directorate Identifier 2013-NE-22-AD;
Amendment 39-17679; AD 2013-24-05]
RIN 2120-AA64
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Turbomeca S.A. Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1,
1S, and 1S1 turboshaft engines. This AD requires a one-time inspection
of the free turbine (FT) module (M04) for the affected Turbomeca S.A.
Arriel 1 engines and, if a discrepancy is found, repair of the affected
module. This AD was prompted by a ``chip illumination event'' in flight
on a Turbomeca S.A. Arriel 1 engine. We are issuing this AD to prevent
a loss of FT bearing lubrication, resulting in FT module failure,
damage to the engine, and damage to the aircraft.
DATES: This AD becomes effective January 28, 2014.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of January 28,
2014.
ADDRESSES: The Docket Operations office is located at Docket Management
Facility, U.S. Department of Transportation, 1200 New Jersey Avenue
SE., West Building Ground Floor, Room W12-140, Washington, DC 20590-
0001.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains this AD, the mandatory continuing
airworthiness information (MCAI), the regulatory evaluation, any
comments received, and other

information. The street address for the Docket Operations office
(phone: 800-647-5527) is provided in the ADDRESSES section. Comments
will be available in the AD docket shortly after receipt.

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 August 12, 2013 (78 FR
48824). The NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
A ``chip light illumination'' event in flight on an ARRIEL 1C2
engine was reported to Turbomeca. Following the event, which
resulted from Free Turbine front bearing deterioration, the
investigation revealed that the loss of the Free Turbine (FT)
bearing module has led to a major disruption in the lubrication of
the FT module (M04) bearings. The root cause of the event has been
attributed to incorrect bonding of the Free Turbine Bearing Plug,
accomplished during the repair process in an identified Repair
Center. Consequently, it was possible to identify a batch of Modules
M04 which are potentially affected.
You may examine the MCAI in the AD docket on the Internet at
http://www.regulations.gov/#!documentDetail;D=FAA-2013-0557-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (78 FR 48824, August 12,
2013).
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 will affect about 5 engines of U.S.
registry. We also estimate that it will take about 1 hour per product
to comply with this AD. The average labor rate is $85 per hour.
Required parts will cost about $13 per engine. Based on these figures,
we estimate the cost of this AD on U.S. operators to be $1,765.
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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
