Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2018– 0209, dated September 21, 2018 (EASA AD 2018–0209), to correct an unsafe condition for Airbus Helicopters (formerly Eurocopter, Eurocopter France, Aerospatiale) Model AS 332 C, AS 332 C1, AS 332 L, AS 332 L1, and AS 332 L2 helicopters, except those with modification 0726383. EASA advises that during production of AS332 helicopters, closure of the fuel tank drains with plugs was implemented. EASA states that this closure disregards compliance with an airworthiness certification requirement and in the event of fuel leakage in flight, a closed fuel drain creates the risk of fuel accumulation and/or migration to an adjacent area. EASA advises this area may contain electrical equipment that could be susceptible to creating a source of ignition. EASA states this condition, if not corrected, could result in the ignition of fuel vapors, resulting in a fire causing damage to the helicopter or injury to the occupants. Accordingly, EASA AD 2018–0209 requires modification of the draining system of the fuel tank compartments by removing the drain plugs from the fuel tank compartments located under the bottom structure. FAA’s Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that an unsafe condition is likely to exist or develop on other products of the same type designs. Related Service Information Under 1 CFR Part 51 The FAA reviewed Airbus Helicopter Alert Service Bulletin No. AS332– E:\FR\FM\03DEP1.SGM 03DEP1 Federal Register / Vol. 84, No. 232 / Tuesday, December 3, 2019 / Proposed Rules 53.01.62, Revision 1, dated May 28, 2019 (ASB AS332–53.01.62, Revision 1), for Model AS332C, AS332C1, AS332L, AS332L1, and AS332L2 helicopters. This service information contains procedures for removing the drain plugs from the fuel tank compartments located under the bottom structure of the helicopter. This service information also specifies that the number of drain plugs varies depending on the version of the helicopter. 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. Other Related Service Information The FAA also reviewed Airbus Helicopters ASB No. AS332–53.01.62, Revision 0, dated June 7, 2018 (AS332– 53.01.62, Revision 0). AS332–53.01.62, Revision 0, contains the same procedures as AS332–53.01.62, Revision 1. However, AS332–53.01.62, Revision 1, also addresses military versions. Proposed AD Requirements This proposed AD would require removing the drain plugs from the fuel tank compartments. lotter on DSKBCFDHB2PROD with PROPOSALS Costs of Compliance The FAA estimates that this proposed AD would affect 11 helicopters of U.S. Registry. The FAA estimates that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per workhour. Removing the 6 drain plugs installed on Model AS332C and AS332C1 helicopters would take about 2 workhours for an estimated cost of $170 per helicopter and $170 for the U.S. fleet size of 1 helicopter. Removing the 7 drain plugs installed on Model AS332L, AS332L1, and AS332L2 helicopters would take about 2 work-hours for an estimated cost of $170 per helicopter and $1,700 for the U.S. fleet size of 10 helicopters. 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. The FAA is 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 VerDate Sep<11>2014 17:32 Dec 02, 2019 Jkt 250001 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 The FAA 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. Will not affect intrastate aviation in Alaska, and 3. 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. The FAA prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2018-0209, dated September 21, 
2018 (EASA AD 2018-0209), to correct an unsafe condition for Airbus 
Helicopters (formerly Eurocopter, Eurocopter France, Aerospatiale) 
Model AS 332 C, AS 332 C1, AS 332 L, AS 332 L1, and AS 332 L2 
helicopters, except those with modification 0726383.
    EASA advises that during production of AS332 helicopters, closure 
of the fuel tank drains with plugs was implemented. EASA states that 
this closure disregards compliance with an airworthiness certification 
requirement and in the event of fuel leakage in flight, a closed fuel 
drain creates the risk of fuel accumulation and/or migration to an 
adjacent area. EASA advises this area may contain electrical equipment 
that could be susceptible to creating a source of ignition. EASA states 
this condition, if not corrected, could result in the ignition of fuel 
vapors, resulting in a fire causing damage to the helicopter or injury 
to the occupants.
    Accordingly, EASA AD 2018-0209 requires modification of the 
draining system of the fuel tank compartments by removing the drain 
plugs from the fuel tank compartments located under the bottom 
structure.

FAA's Determination

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's bilateral 
agreement with the European Union, EASA has notified the FAA about the 
unsafe condition described in its AD. The FAA is proposing this AD 
after evaluating all known relevant information and determining that an 
unsafe condition is likely to exist or develop on other products of the 
same type designs.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Airbus Helicopter Alert Service Bulletin No. 
AS332-

Other Related Service Information

    The FAA also reviewed Airbus Helicopters ASB No. AS332-53.01.62, 
Revision 0, dated June 7, 2018 (AS332-53.01.62, Revision 0). AS332-
53.01.62, Revision 0, contains the same procedures as AS332-53.01.62, 
Revision 1. However, AS332-53.01.62, Revision 1, also addresses 
military versions.

Proposed AD Requirements

    This proposed AD would require removing the drain plugs from the 
fuel tank compartments.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 11 helicopters 
of U.S. Registry. The FAA estimates that operators may incur the 
following costs in order to comply with this AD. Labor costs are 
estimated at $85 per work-hour.
    Removing the 6 drain plugs installed on Model AS332C and AS332C1 
helicopters would take about 2 work-hours for an estimated cost of $170 
per helicopter and $170 for the U.S. fleet size of 1 helicopter.
    Removing the 7 drain plugs installed on Model AS332L, AS332L1, and 
AS332L2 helicopters would take about 2 work-hours for an estimated cost 
of $170 per helicopter and $1,700 for the U.S. fleet size of 10 
helicopters.

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.
    The FAA is 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

    The FAA 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. Will not affect intrastate aviation in Alaska, and
    3. 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.
    The FAA prepared an economic evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
