Airworthiness Directives; Sicma Aero Seat Passenger Seat 
Assemblies, Installed on, But Not Limited to, ATR-GIE Avions de 
Transport R[eacute]gional Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for Sicma 
Aero Seat Model 9401, 9402, 9404, 9405, 9406, 9407, 9408, and 9409 
series passenger seat assemblies, installed on, but not limited to, 
ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 
airplanes. This AD results from mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as:

    Several occurrences of cracked central and lateral spreaders on 
passenger seats models 9401 and 9402 * * *.
    This condition, if not corrected, can lead to further cracking 
of the seat spreaders, causing injury to passengers or crew members 
during heavy turbulence in flight or in the event of an emergency 
landing.
* * * * *

    This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

DATES: This AD becomes effective November 21, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of November 21, 
2011.
    We must receive comments on this AD by December 19, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2008-0097, dated May 20, 2008 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Several occurrences of cracked central and lateral spreaders on 
passenger seats models 9401 and 9402 have been reported to Sicma 
Aero Seat.
    This condition, if not corrected, can lead to further cracking 
of the seat spreaders, causing injury to passengers or crew members 
during heavy turbulence in flight or in the event of an emergency 
landing.
    For the reasons stated above, this [EASA] Airworthiness 
Directive (AD) requires repetitive [detailed] inspections of the 
affected seats and, depending on findings, the repair or replacement 
of damaged spreaders with an improved design (`Amendment B' 
standard). The replacement of all spreaders (i.e. modification to 
`Amendment B' standard) terminates the repetitive inspection 
requirements.
* * * * *

    You may obtain further information by examining the MCAI in the AD 
docket.

unsafe condition identified in the MCAI.

dated June 30, 2008.
    <bullet> Sicma Aero Seat Service Bulletin 94-25-012, Revision 1,

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

Differences Between the AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a note within the AD.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2011-1163; Directorate 
Identifier 2011-NM-022-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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 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 this AD:
    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); 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

    (b) None.

Applicability

    (c) This AD applies to Sicma Aero Seat Model 9401, 9402, 9404, 
9505, 9406, 9407, 9408, and 9409 series passenger seat assemblies, 
all part numbers, except front row and aft facing seats, and those

area subject to the requirements of this AD. For airplanes that have 
been modified, altered, or repaired so that the performance of the 
requirements of this AD is affected, the owner/operator must request 
approval for an alternative method of compliance (AMOC) according to 
paragraph (k)(1) of this AD. The request should include an 
assessment of the effect of the modification, alteration, or repair 
on the unsafe condition addressed by this AD; and, if the unsafe 
condition has not been eliminated, the request should include 
specific proposed actions to address it.
