Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent PO 00000 Frm 00036 Fmt 4702 Sfmt 4702 26905 for the Member States of the European Community, has issued EASA AD 2014– 0059, dated March 10, 2014 (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Two uncommanded in-flight shutdowns on Makila 2A/2A1 engines have been reported. The results of the technical investigations concluded that these events were caused by deterioration of the splines on the highpressure (HP) fuel pump drive link, which eventually interrupted the fuel supply to the engine. This condition, if not detected and corrected, could lead to further cases of uncommanded engine in-flight shutdown, and may ultimately lead to an emergency landing. We are proposing this AD to prevent failure of the HP fuel pump, which could lead to an in-flight shutdown, damage to the engine, and forced landing or accident. You may obtain further information by examining the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2014– 0219. Relevant Service Information Turbomeca S.A. has issued Mandatory Service Bulletin (MSB) No. 298 73 2818, Version F, dated March 5, 2014. The MSB describes procedures for cleaning and visually inspecting the splines of the HP fuel pump/metering valve and the module M01 drive gear for wear, corrosion, scaling, pitting, and chafing. FAA’s Determination and Requirements of This Proposed 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 proposing 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 proposed AD would require initial and repetitive visual inspections, and replacement of the splines of the HP fuel pump/metering valve and the module M01 drive gear, if necessary. Costs of Compliance We estimate that this proposed AD affects 8 engines installed on helicopters of U.S. registry. We also estimate that it would take about 2 hours per engine to E:\FR\FM\12MYP1.SGM 12MYP1 26906 Federal Register / Vol. 79, No. 91 / Monday, May 12, 2014 / Proposed Rules comply with this proposed AD. The average labor rate is $85 per hour. Required parts cost about $750 per engine. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $1,360. 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 tkelley on DSK3SPTVN1PROD with PROPOSALS We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation: (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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2014-0059, dated March 10, 2014 (referred to hereinafter as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    Two uncommanded in-flight shutdowns on Makila 2A/2A1 engines 
have been reported. The results of the technical investigations 
concluded that these events were caused by deterioration of the 
splines on the high-pressure (HP) fuel pump drive link, which 
eventually interrupted the fuel supply to the engine.
    This condition, if not detected and corrected, could lead to 
further cases of uncommanded engine in-flight shutdown, and may 
ultimately lead to an emergency landing.

    We are proposing this AD to prevent failure of the HP fuel pump, 
which could lead to an in-flight shutdown, damage to the engine, and 
forced landing or accident.
    You may obtain further information by examining the MCAI in the AD 
docket on the Internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2014-0219.

Relevant Service Information

    Turbomeca S.A. has issued Mandatory Service Bulletin (MSB) No. 298 
73 2818, Version F, dated March 5, 2014. The MSB describes procedures 
for cleaning and visually inspecting the splines of the HP fuel pump/
metering valve and the module M01 drive gear for wear, corrosion, 
scaling, pitting, and chafing.

FAA's Determination and Requirements of This Proposed 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 proposing 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 proposed AD would require initial and repetitive visual 
inspections, and replacement of the splines of the HP fuel pump/
metering valve and the module M01 drive gear, if necessary.

Costs of Compliance

    We estimate that this proposed AD affects 8 engines installed on 
helicopters of U.S. registry. We also estimate that it would take about 
2 hours per engine to

[[Page 26906]]

comply with this proposed AD. The average labor rate is $85 per hour. 
Required parts cost about $750 per engine. Based on these figures, we 
estimate the cost of this proposed AD on U.S. operators to be $1,360.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (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.
