[Docket No. FAA-2013-0480; Directorate Identifier 2012-SW-090-AD]
RIN 2120-AA64


Airworthiness Directives; Eurocopter France (Eurocopter) 
Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Eurocopter Model SA-365N, SA-365N1, AS-365N2, AS 365 N3, EC 155B, 
EC155B1, AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters with 
certain EADS Sogerma pilot and co-pilot seats installed. This proposed 
AD would require inspecting the rear beam of each seat to determine if 
all of the weld beads are present and replacing the seat if any weld 
bead is missing. This proposed AD is prompted by a maintenance 
inspection that discovered a missing weld bead on the rear beam of a 
pilot seat. The proposed actions are intended to prevent failure of the 
pilot and co-pilot seats and subsequent injury to the pilot or co-
pilot.

DATES: We must receive comments on this proposed AD by August 5, 2013.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your 
comments electronically.

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. 2012-0206, dated October 2, 2012 (AD 2012-0206), to correct an 
unsafe condition for Eurocopter Model SA-365N, SA-365N1, AS-365N2, AS 
365 N3, EC 155B, EC155B1, AS332C, AS332C1, AS332L, AS332L1, AS332L2, 
and EC225LP helicopters with certain EADS Sogerma pilot seats, part 
number (P/N) 2510106-03-00 or P/N 2510106-06-00. EASA advises that 
during a maintenance inspection, a weld bead was found missing on the 
rear beam of an EADS Sogerma pilot seat. According to EASA, this non-
conformity impairs the seat anti-crash function and may be present on a 
limited number of seats installed on Eurocopter helicopters. EASA 
states that this condition, if not corrected, could lead to pilot 
injury following a hard landing following an emergency.
    To address this unsafe condition, EASA issued AD No. 2012-0084, 
dated May 16, 2012 (AD 2012-0084), to require inspecting the flight 
crew seats, replacing any improperly welded seat, and marking all 
correctly welded seats. After issuing AD 2012-0084, a missing weld bead 
was discovered on another part of the seat rear beam that was not 
required to be inspected. As a result, EASA issued AD 2012-0206, which 
superseded AD 2012-0084, to revise the inspection procedure and add new 
areas of the rear beam of the seat to be inspected.

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 unsafe condition is likely 
to exist or develop on other helicopters of the same type design.

Related Service Information

    Eurocopter has issued Alert Service Bulletin (ASB) No. AS365-
25.01.18 for Model SA-365N, SA-365 N1, AS-365N2, and AS 365 N3 
helicopters; ASB No. EC155-25A114 for Model EC155 B and EC155B1 
helicopters; ASB No. AS332-25.02.49 for model AS332C, AS332L, AS332L1, 
and AS332L2 helicopters; and ASB No. EC225-25A110 for Model EC225LP 
helicopters; all Revision 1, dated August 9, 2012. The ASBs incorporate 
the procedures in EADS Sogerma Inspection Service Bulletin No. 2510106-
25-888, Revision 1, dated July 16, 2012, for inspecting the rear beam 
of the pilot and co-pilot seats to verify all of the weld beads are 
present. The complete EADS Sogerma bulletin is contained in the 
Appendix of the ASBs. EASA classified these ASBs as mandatory and 
issued AD 2012-0206 to ensure the continued airworthiness of these 
helicopters.

Proposed AD Requirements

    This proposed AD would require, within 50 hours time-in-service 
(TIS), inspecting the rear beam of each pilot and co-pilot seat to 
determine if any weld beads are missing. If any weld beads are missing, 
before further flight, this proposed AD would require removing the seat 
from the helicopter and replacing it with an airworthy seat.

Differences Between This Proposed AD and the EASA AD

    The EASA AD allows compliance within 3 months or 50 flight hours, 
whichever occurs earlier; the proposed AD requires compliance within 50 
hours TIS. The EASA AD applies to Model AS332C1 helicopters. This 
proposed AD does not because this model is not FAA type-certificated.

Costs of Compliance

    We estimate that this proposed AD would affect 65 helicopters of 
U.S. Registry.
    We estimate that operators may incur the following costs in order 
to comply with this AD. At an average labor rate of $85 per hour, 
inspecting the seats would require about .2 work-hour, for a cost per 
helicopter of $17 and a total cost to U.S. operators of $1,105. 
Replacing a seat with a missing weld bead would require about 1 work-
hour, and required parts would cost about $30,251, for a cost per 
helicopter of $30,336.
    According to Eurocopter's service information some of the costs of 
this proposed AD may be covered under warranty, thereby reducing the 
cost impact on affected individuals. We do not control warranty 
coverage by Eurocopter. Accordingly, we have included all costs in our 
cost estimate.

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.
