We will also post a report summarizing each substantive verbal contact with FAA personnel concerning this AD. 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. asabaliauskas on DSK3SPTVN1PROD with RULES 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 VerDate Sep<11>2014 15:43 Mar 21, 2016 Jkt 238001 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, PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 15155 (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.

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

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):

2016-06-09 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.
