Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2011– 0190, dated September 30, 2011 (AD No. 2011–0190), to correct an unsafe condition for the Eurocopter France EC 155, SA 366, SA 365, and AS 365 model helicopters, except those with certain modifications. EASA reports that the fuel tank drains were closed with plugs during production to maintain buoyancy during emergency landings in water. EASA states that this closing of the fuel tank drains with plugs ‘‘disregards compliance with an airworthiness certification requirement’’ and, in the event of a fuel leak in flight, creates ‘‘the risk of fuel accumulation and/or migration’’ to an adjacent area that may contain electrical equipment ‘‘susceptible of constituting a source of ignition.’’ EASA states that this condition, if not corrected, could result in ignition of fuel vapors, ‘‘resulting in a fire and consequent damage to the helicopter, or injury to its occupants.’’ As a result, EASA required modification of the fuel tank compartments’ draining system. 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 its AD. We are proposing this AD because we evaluated all known relevant information and determined that an E:\FR\FM\26NOP1.SGM 26NOP1 Federal Register / Vol. 77, No. 227 / Monday, November 26, 2012 / Proposed Rules unsafe condition is likely to exist or develop on other products of these same type designs. require two work-hours for a total cost of $170 per helicopter. Related Service Information Eurocopter issued Alert Service Bulletin (ASB) No. EC155–53A031 for its B and B1 model helicopters, ASB No. AS366–53.11 for its G1 model helicopters, and ASB No. AS365– 53.00.50 for its N, N1, N2 and N3 model helicopters. The ASBs were all dated May 3, 2011, and were all followed with Revision 1 dated September 21, 2011. For helicopters not equipped with emergency buoyancy fixed parts, the ASBs describe procedures to modify the fuel tank draining system by removing drain plugs in the fuel tanks, to make draining possible. For helicopters equipped with emergency buoyancy fixed parts, the ASBs contain additional procedures to seal one drain plug per fuel tank compartment and to install new drain points and self-sealing drain valves in specified fuel tanks. EASA AD No. 2011–0190 classifies these ASBs as mandatory to ensure the airworthiness of these helicopters. 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. mstockstill on DSK4VPTVN1PROD with PROPOSALS Proposed AD Requirements This proposed AD would require compliance with certain sections within paragraph 3.B.2 of the manufacturer’s service bulletins. Helicopters equipped with emergency buoyancy fixed parts would be required to comply within six months, and helicopters not equipped with emergency buoyancy fixed parts would be required to comply within 110 hours time-in-service. Costs of Compliance We estimate that this proposed AD would affect 46 helicopters of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we would expect the following costs: Sealing drain plugs, and installing new drain points and self-sealing drain valves at other locations on helicopters equipped with emergency buoyancy fixed parts would require 16 workhours. Parts would cost $11,154 for a total cost of $12,514 per helicopter. For helicopters equipped with emergency buoyancy fixed parts and a sixth fuel tank, this work would instead require 17 work-hours for a total cost of $12,599 per helicopter. Removing drain plugs on helicopters not equipped with emergency buoyancy fixed parts would require one workhour and no parts for a total cost of $85 per helicopter. For helicopters not equipped with emergency buoyancy fixed parts but equipped with a sixth fuel tank, this work would instead VerDate Mar<15>2010 16:40 Nov 23, 2012 Jkt 229001 Authority for This Rulemaking 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, 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. We prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Background On May 14, 2009, Embraer S.A. applied for a type certificate for their new Model EMB–550 airplane. The Model EMB–550 airplane is the first of a new family of jet airplanes designed for corporate flight, fractional, charter, and private owner operations. The aircraft has a conventional configuration with low wing and T-tail empennage. The primary structure is metal with composite empennage and control surfaces. The Model EMB–550 airplane is designed for 8 passengers, with a maximum of 12 passengers. It is equipped with two Honeywell HTF7500–E medium bypass ratio turbofan engines mounted on aft fuselage pylons. Each engine produces approximately 6,540 pounds of thrust for normal takeoff. The primary flight controls consist of hydraulically powered fly-by-wire elevators, ailerons, and rudder, controlled by the pilot or copilot sidestick. The flight control system for the Model EMB–550 airplane does not have a direct mechanical link or a linear gain between the airplane flight control surface and the pilot’s cockpit control device, which is not accounted for in Title 14, Code of Federal Regulations (14 CFR) 25.349(a). Instead, a flight control computer commands the airplane flight control surfaces, based on input received from the cockpit control device. The pilot input is modified by the flight control computer before the command is given to the flight control surface. Type Certification Basis Under the provisions of 14 CFR 21.17, Embraer S.A. must show that the Model EMB–550 airplane meets the applicable provisions of part 25, as amended by Amendments 25–1 through 25–127 thereto. If the Administrator finds that the applicable airworthiness regulations (i.e., 14 CFR part 25) do not contain adequate or appropriate safety standards for the Model EMB–500 airplane because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16. Special conditions are initially applicable to the model for which they E:\FR\FM\26NOP1.SGM 26NOP1

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
No. 2011-0190, dated September 30, 2011 (AD No. 2011-0190), to correct 
an unsafe condition for the Eurocopter France EC 155, SA 366, SA 365, 
and AS 365 model helicopters, except those with certain modifications. 
EASA reports that the fuel tank drains were closed with plugs during 
production to maintain buoyancy during emergency landings in water. 
EASA states that this closing of the fuel tank drains with plugs 
``disregards compliance with an airworthiness certification 
requirement'' and, in the event of a fuel leak in flight, creates ``the 
risk of fuel accumulation and/or migration'' to an adjacent area that 
may contain electrical equipment ``susceptible of constituting a source 
of ignition.'' EASA states that this condition, if not corrected, could 
result in ignition of fuel vapors, ``resulting in a fire and consequent 
damage to the helicopter, or injury to its occupants.'' As a result, 
EASA required modification of the fuel tank compartments' draining 
system.

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 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an

[[Page 70383]]

unsafe condition is likely to exist or develop on other products of 
these same type designs.

Related Service Information

    Eurocopter issued Alert Service Bulletin (ASB) No. EC155-53A031 for 
its B and B1 model helicopters, ASB No. AS366-53.11 for its G1 model 
helicopters, and ASB No. AS365-53.00.50 for its N, N1, N2 and N3 model 
helicopters. The ASBs were all dated May 3, 2011, and were all followed 
with Revision 1 dated September 21, 2011.
    For helicopters not equipped with emergency buoyancy fixed parts, 
the ASBs describe procedures to modify the fuel tank draining system by 
removing drain plugs in the fuel tanks, to make draining possible. For 
helicopters equipped with emergency buoyancy fixed parts, the ASBs 
contain additional procedures to seal one drain plug per fuel tank 
compartment and to install new drain points and self-sealing drain 
valves in specified fuel tanks. EASA AD No. 2011-0190 classifies these 
ASBs as mandatory to ensure the airworthiness of these helicopters.

Proposed AD Requirements

    This proposed AD would require compliance with certain sections 
within paragraph 3.B.2 of the manufacturer's service bulletins. 
Helicopters equipped with emergency buoyancy fixed parts would be 
required to comply within six months, and helicopters not equipped with 
emergency buoyancy fixed parts would be required to comply within 110 
hours time-in-service.

Costs of Compliance

    We estimate that this proposed AD would affect 46 helicopters of 
U.S. Registry and that labor costs average $85 per work-hour. Based on 
these estimates, we would expect the following costs:
    Sealing drain plugs, and installing new drain points and self-
sealing drain valves at other locations on helicopters equipped with 
emergency buoyancy fixed parts would require 16 work-hours. Parts would 
cost $11,154 for a total cost of $12,514 per helicopter. For 
helicopters equipped with emergency buoyancy fixed parts and a sixth 
fuel tank, this work would instead require 17 work-hours for a total 
cost of $12,599 per helicopter.
    Removing drain plugs on helicopters not equipped with emergency 
buoyancy fixed parts would require one work-hour and no parts for a 
total cost of $85 per helicopter. For helicopters not equipped with 
emergency buoyancy fixed parts but equipped with a sixth fuel tank, 
this work would instead require two work-hours for a total cost of $170 
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 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, 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    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]

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

Eurocopter France: Docket No. FAA-2012-1214; Directorate Identifier 
2011-SW-071-AD.

(a) Applicability

    This AD applies to Eurocopter France Model EC 155B, EC155B1, and 
SA-366G1 helicopters, except those with modification 365A084485.00, 
or modifications 0753C98 and 0745C96; and Model SA-365N, SA-365N1, 
AS-365N2, and AS 365 N3 helicopters, except those with modifications 
0753C98, 0745C96, and (if a sixth fuel tank is installed) 
365A081003.00, or modification 365A081003.00 and (if a sixth fuel 
tank is installed) 365A084485.00.

(b) Unsafe Condition

    This AD defines the unsafe condition as a closed fuel tank drain 
that, in the event of a fuel leak, could result in fuel accumulating 
in an area containing electrical equipment or other ignition source. 
This condition could result in a fire in the helicopter.

(c) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(d) Required Actions

    (1) Within 110 hours time-in-service (TIS):
