We are adopting a new airworthiness directive (AD) for certain Turbomeca S.A. Makila 2A and 2A1 turboshaft engines. This AD requires tightening the nut attaching the swivel union to the engine power turbine module M04. This AD was prompted by two occurrences of commanded in-flight shutdown following low oil pressure warning. We are issuing this AD to prevent loosening of the nut and oil leakage from the low-pressure oil system, which could lead to in-flight shutdown of the engine and forced landing.

Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Turbomeca S.A. Makila 2A and 2A1 turboshaft engines. This AD requires 
tightening the nut attaching the swivel union to the engine power 
turbine module M04. This AD was prompted by two occurrences of 
commanded in-flight shutdown following low oil pressure warning. We are 
issuing this AD to prevent loosening of the nut and oil leakage from 
the low-pressure oil system, which could lead to in-flight shutdown of 
the engine and forced landing.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2016-0016, dated January 15, 2016 (referred to hereinafter as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    Two occurrences of commanded in-flight shut down following low 
oil pressure warning were reported. In both cases the nut attaching 
the swivel union to the power turbine module 04 was found completely 
loose. After further investigation, it was determined that the 
application of Turbomeca Service Bulletin (SB) No. 298 79 2831 may 
have led to incorrect torque application or loosening of the nut.

    Turbomeca S.A. has issued Alert Mandatory Service Bulletin No. A298 
79 2835, Version A, dated January 14, 2016, to provide guidance to 
assist operators in resolving this unsafe condition. 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-2016-2701.

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of France 
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 issuing 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 AD requires tightening the nut attaching the swivel union 
to the engine power turbine module M04.

Related Service Information

    Turbomeca S.A. has issued Alert Mandatory Service Bulletin No. A298 
79 2835, Version A, dated January 14, 2016. The service information 
describes procedures for tightening the nut attaching the swivel union 
to the engine power turbine module (M04). 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 document.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
operators are required to take action with 7 days or 30 engine hours 
after the effective date of this AD. Therefore, we find that notice and 
opportunity for prior public comment are impracticable and that good 
cause exists for making this amendment effective in less than 30 days.

Costs of Compliance

    We estimate that this AD affects 10 engines installed on airplanes 
of U.S. registry. We also estimate that it will take about 1 hour per 
engine to comply with this AD. The average labor rate is $85 per hour. 
No additional parts are required. Based on these figures, we estimate 
the total cost of the AD to U.S. operators to be $850.

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:

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

2016-06-09 Turbomeca S.A.: Amendment 39-18440; Docket No. FAA-2016-
2701; Directorate Identifier 2016-NE-03-AD.

(a) Effective Date

    This AD is effective April 6, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Turbomeca S.A. Makila 2A and 2A1 
turboshaft engines that have incorporated Turbomeca S.A. Service 
Bulletin No. 298 79 2831, Version B, dated November 13, 2015, or 
earlier.

(d) Reason

    This AD was prompted by two occurrences of in-flight shutdowns 
as a result of the nut, attaching the swivel union to the power 
turbine module M04, coming loose. We are issuing this AD to prevent 
loosening of the nut, and oil leakage from the low pressure oil 
system, which could lead to in-flight shutdown of the engine and 
forced landing.

(e) Actions and Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    (1) Within 30 engine hours or 7 days after the effective date of 
this AD, whichever occurs first, apply 15 Newton-meters torque to 
the nut, part number 9560130990, attaching the swivel union to the 
engine power turbine module M04. Use a backup wrench to prevent the 
swivel union from rotating.

[[Page 15156]]

(f) Alternative Methods of Compliance (AMOCs)

    The Manager, Engine Certification Office, FAA, may approve AMOCs 
for this AD. Use the procedures found in 14 CFR 39.19 to make your 
request. You may email your request to: [email protected].
