ADDRESSES: On November 25, 2013, at 78 FR 70242, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to Eurocopter France (now Airbus Helicopters) Model EC225LP helicopters with a tangential gearbox, part number 200181 or 704A34112012. The NPRM proposed to require measuring the operating load of the cockpit fuel shut-off controls and replacing the tangential gearbox if the operating load threshold is exceeded. The proposed requirements were intended to prevent the jamming of the controls so that a pilot can shut down an engine during an engine fire or during an emergency landing. The NPRM was prompted by AD No. 2013–0098–E, dated April 24, 2013, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Eurocopter France (now Airbus Helicopters) Model EC 225 LP helicopters. EASA advises that during PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 31855 maintenance on a helicopter, the LH side of the cockpit’s emergency shutdown controls were reported jammed, making it impossible to operate the LH fuel shut-off and the general cutout handles. EASA states that this condition could lead to failure to manually operate the emergency shutdown controls during an emergency landing or fire. To address this unsafe condition, EASA AD No. 2013–0098–E requires an operating load check of the two cockpit fuel shut-off handles and, depending on findings, lubrication and/ or replacement of the two tangential gearboxes. Since we issued the NPRM, Eurocopter France changed its name to Airbus Helicopters, Inc. This AD reflects that change and updates the contact information to obtain service documentation. Comments We gave the public the opportunity to participate in developing this AD, but we received no comments on the NPRM (78 FR 70242, November 25, 2013). FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. 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 helicopters of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed except for the minor changes previously described. These changes are consistent with the intent of the proposals in the NPRM (78 FR 70242, November 25, 2013) and will not increase the economic burden on any operator nor increase the scope of this AD. Differences Between This AD and the EASA AD The EASA AD requires differing compliance times based on when the helicopter’s original Certificate of Airworthiness or Export Certificate of Airworthiness was issued. This AD makes no distinction regarding compliance times because there are only 4 affected aircraft on the U.S. registry. Related Service Information Eurocopter issued Emergency Alert Service Bulletin No. 76A001, Revision 0, dated April 22, 2013, for the Model E:\FR\FM\03JNR1.SGM 03JNR1 31856 Federal Register / Vol. 79, No. 106 / Tuesday, June 3, 2014 / Rules and Regulations EC225LP civil helicopter and the Model EC725AP military helicopter to notify its operators that during a scheduled inspection of the fuel shut-off controls, a mechanic noticed that one of the shutoff controls jammed. This jamming made maneuvering the fuel shut-off and the general cut-out controls impossible. After an investigation, Eurocopter determined that the jamming originated in the tangential gearbox installed on this control. Traces of corrosion were observed on the internal bearings of the LH tangential gearbox, Eurocopter reported. The jamming of the fuel cutoff control prevents the engine input fuel valve and the engine compartment ventilation flap from closing and prevents the activation of the general cut-out control. Eurocopter consequently called for a mandatory ‘‘check’’ of the fuel shut-off valve maneuvering loads, lubricating the tangential gearbox bearings, and depending on the load measurement, replacing the tangential gearbox. wreier-aviles on DSK5TPTVN1PROD with RULES Costs of Compliance We estimate that this AD affects 4 helicopters of U.S. Registry and that labor costs average $85 a work-hour. Based on these estimates, we expect the following costs: • Measuring the operating load of the two cockpit fuel shut-off controls require .25 work-hours for a labor cost of about $21, or $84 for the U.S. fleet. No parts are needed. • Lubricating the tangential gearbox requires 4 work-hours. The cost of consumable materials is minimal for a total cost of $340 per helicopter. • Replacing the tangential gearbox requires 4 work-hours for a labor cost of $340. Parts cost $4,943 for a total cost of $5,283 per helicopter. 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 VerDate Mar<15>2010 15:19 Jun 02, 2014 Jkt 232001 helicopters identified in this rulemaking action. (c) Effective Date Regulatory Findings 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) Is not a ‘‘significant rule’’ under 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 an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Emergency AD No. 2013–0265–E, dated October 30, 2013, to correct an unsafe condition for Agusta Model A109A, A109A II, A109C, A109E, A109K2, A109LUH, A109S, AW109SP, A119, and AW119 MKII helicopters. EASA advises that during a scheduled inspection of the rotating control installation, two nuts, part number (P/N) MS21042–4, which connect the swashplate support to the upper case of the main transmission were found cracked. EASA states a subsequent investigation determined that the cracks in the nuts resulted from a production deficiency, which caused hydrogen embrittlement, at the nut manufacturer. EASA also states that this condition, if not detected and corrected, could lead to failure of the main rotor function and subsequent loss of control of the helicopter. The EASA Emergency AD requires repetitive inspections of each nut, P/N MS21042–4, for a crack, replacing any nut that has a crack with a different part-numbered nut, and, within 3 months, replacing each nut that does not have a crack with a different part-numbered nut. EASA Emergency AD 2013–0265–E also prohibits installing a nut, P/N MS21042–4, to connect the swashplate support to the upper case on any helicopter.

SUPPLEMENTARY INFORMATION: 

Discussion

    On November 25, 2013, at 78 FR 70242, the Federal Register 
published our notice of proposed rulemaking (NPRM), which proposed to 
amend 14 CFR part 39 by adding an AD that would apply to Eurocopter 
France (now Airbus Helicopters) Model EC225LP helicopters with a 
tangential gearbox, part number 200181 or 704A34112012. The NPRM 
proposed to require measuring the operating load of the cockpit fuel 
shut-off controls and replacing the tangential gearbox if the operating 
load threshold is exceeded. The proposed requirements were intended to 
prevent the jamming of the controls so that a pilot can shut down an 
engine during an engine fire or during an emergency landing.
    The NPRM was prompted by AD No. 2013-0098-E, dated April 24, 2013, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union, to correct an unsafe condition for Eurocopter 
France (now Airbus Helicopters) Model EC 225 LP helicopters. EASA 
advises that during maintenance on a helicopter, the LH side of the 
cockpit's emergency shutdown controls were reported jammed, making it 
impossible to operate the LH fuel shut-off and the general cut-out 
handles. EASA states that this condition could lead to failure to 
manually operate the emergency shutdown controls during an emergency 
landing or fire. To address this unsafe condition, EASA AD No. 2013-
0098-E requires an operating load check of the two cockpit fuel shut-
off handles and, depending on findings, lubrication and/or replacement 
of the two tangential gearboxes.
    Since we issued the NPRM, Eurocopter France changed its name to 
Airbus Helicopters, Inc. This AD reflects that change and updates the 
contact information to obtain service documentation.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we received no comments on the NPRM (78 FR 70242, November 
25, 2013).

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
the EASA AD. 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 helicopters of these same 
type designs and that air safety and the public interest require 
adopting the AD requirements as proposed except for the minor changes 
previously described. These changes are consistent with the intent of 
the proposals in the NPRM (78 FR 70242, November 25, 2013) and will not 
increase the economic burden on any operator nor increase the scope of 
this AD.

Differences Between This AD and the EASA AD

    The EASA AD requires differing compliance times based on when the 
helicopter's original Certificate of Airworthiness or Export 
Certificate of Airworthiness was issued. This AD makes no distinction 
regarding compliance times because there are only 4 affected aircraft 
on the U.S. registry.

Related Service Information

    Eurocopter issued Emergency Alert Service Bulletin No. 76A001, 
Revision 0, dated April 22, 2013, for the Model

EC225LP civil helicopter and the Model EC725AP military helicopter to 
notify its operators that during a scheduled inspection of the fuel 
shut-off controls, a mechanic noticed that one of the shut-off controls 
jammed. This jamming made maneuvering the fuel shut-off and the general 
cut-out controls impossible. After an investigation, Eurocopter 
determined that the jamming originated in the tangential gearbox 
installed on this control. Traces of corrosion were observed on the 
internal bearings of the LH tangential gearbox, Eurocopter reported. 
The jamming of the fuel cut-off control prevents the engine input fuel 
valve and the engine compartment ventilation flap from closing and 
prevents the activation of the general cut-out control.
    Eurocopter consequently called for a mandatory ``check'' of the 
fuel shut-off valve maneuvering loads, lubricating the tangential 
gearbox bearings, and depending on the load measurement, replacing the 
tangential gearbox.

Costs of Compliance

    We estimate that this AD affects 4 helicopters of U.S. Registry and 
that labor costs average $85 a work-hour. Based on these estimates, we 
expect the following costs:
     Measuring the operating load of the two cockpit fuel shut-
off controls require .25 work-hours for a labor cost of about $21, or 
$84 for the U.S. fleet. No parts are needed.
     Lubricating the tangential gearbox requires 4 work-hours. 
The cost of consumable materials is minimal for a total cost of $340 
per helicopter.
     Replacing the tangential gearbox requires 4 work-hours for 
a labor cost of $340. Parts cost $4,943 for a total cost of $5,283 per 
helicopter.

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 helicopters identified in this 
rulemaking action.

Regulatory Findings

    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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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 an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
