We are adopting a new airworthiness directive (AD) for certain Turbomeca S.A. Arrius 2F turboshaft engines with a certain part number oil pump installed. This AD requires inspection, and if necessary, replacement before further flight of the oil pump driver assembly and/ or the oil pump shaft, or the oil pump itself. This AD was prompted by cases of deterioration of the gas generator front bearing due to a link loss between the pump driver and the oil pump shaft. We are issuing this AD to prevent link loss between the pump driver and the oil pump shaft, which could lead to an engine in-flight shutdown, forced landing, and damage to the helicopter.

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. Arrius 2F turboshaft engines with a certain part number 
oil pump installed. This AD requires inspection, and if necessary, 
replacement before further flight of the oil pump driver assembly and/
or the oil pump shaft, or the oil pump itself. This AD was prompted by 
cases of deterioration of the gas generator front bearing due to a link 
loss between the pump driver and the oil pump shaft. We are issuing 
this AD to prevent link loss between the pump driver and the oil pump 
shaft, which could lead to an engine in-flight shutdown, forced 
landing, and damage to the helicopter.

DATES: This AD becomes effective October 2, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 2, 
2015.

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 May 21, 2015 (80 FR 
29224). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    A risk of an in-flight shutdown (IFSD) has been identified on an 
ARRIUS 2F engine, due to deterioration of gas generator front 
bearing. This could be the result of lack of lubrication,

[[Page 52186]]

due to a link loss between pump driver and oil pump shaft.
    This condition, if not detected and corrected, could lead to 
cases of IFSD, possibly resulting in forced landing with consequent 
damage to the helicopter and injury to occupants.

Related Service Information Under 1 CFR Part 51

    Turbomeca S.A. has issued Mandatory Service Bulletin (MSB) No. 319 
79 4834, Version B, dated October 21, 2014. The MSB describes 
procedures for inspecting the oil pump driver assembly on the oil pump 
shaft, the pump driver splines, and the oil pump splines. This service 
information is reasonably available because the interested parties have 
access to it through their normal course of business or by the means 
identified in the ADDRESSES section of this AD.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 29224, May 21, 
2015).

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 affects about 96 engines installed on 
helicopters of U.S. registry. We also estimate that it would take about 
two hours per engine to comply with this AD. The average labor rate is 
$85 per hour. Required parts would cost about $17,312 per engine. Based 
on these figures, we estimate the cost of this AD on U.S. operators to 
be $1,678,272.

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):

2015-17-18 Turbomeca S.A.: Amendment 39-18251; Docket No. FAA-2015-
0900; Directorate Identifier 2015-NE-12-AD.

(a) Effective Date

    This AD becomes effective October 2, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Turbomeca S.A. Arrius 2F turboshaft 
engines with oil pump, part number (P/N) 0319155050, installed, 
except for:
    (1) Engines, equipped with an oil pump, P/N 0319155050, that 
were overhauled in a Turbomeca repair center after January 1, 2013, 
and
    (2) Engines with a serial number of 34776 or higher, provided 
that the oil pump was not replaced on that engine since the first 
flight of that engine on a helicopter.

(d) Reason

    This AD was prompted by cases of deterioration of the gas 
generator front bearing due to a link loss between the pump driver 
and the oil pump shaft. We are issuing this AD to prevent link loss 
between the pump driver and the oil pump shaft, which could lead to 
an engine in-flight shutdown, forced landing, and damage to the 
helicopter.

(e) Actions and Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    (1) Inspect the pump driver assembly on the oil pump shaft, the 
pump driver splines, and the oil pump splines, using paragraph
