Airworthiness Directives; Sicma Aero Seat; Third Occupant Seat 
Assemblies, 133 Series

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for Sicma Aero Seat third occupant seat assemblies, 133 Series. This 
proposed AD would require visually inspecting the installation of the 
two headrest bushings and installing Mecanindus pins to secure the 
bushings. This proposed AD results from Sicma's determination that 
missing or incorrectly secured bushings could loosen and cause 
disengagement of the headrest from the seat during a high-energy stop 
of the airplane, possibly injuring the seat occupant. We are proposing 
this AD to prevent disengagement of the headrest from the seat during a 
high-energy stop of the airplane that could injure the seat occupant.

DATES: We must receive any comments on this proposed AD by May 1, 2006.

proposed AD.

Discussion

    The Direction Generale de L'Aviation Civile (DGAC), which is the 
airworthiness authority for France, notified us that an unsafe 
condition might exist on Sicma Aero Seat third occupant seat 
assemblies, 133 Series. The DGAC advises that Sicma determined that 
missing or incorrectly secured bushings could loosen, causing 
disengagement of the headrest from the seat during a high-energy stop 
of the airplane, possibly injuring the third seat occupant. This 
proposed AD would require visually inspecting the installation of the 
two headrest bushings and installing Mecanindus pins to secure the 
bushings. We are proposing this AD to prevent disengagement of the 
headrest from the seat during a high-energy stop of the airplane that 
could injure the seat occupant.

Relevant Service Information

    We have reviewed and approved the technical contents of Sicma Aero 
Seat Service Bulletin (SB) 133-25-006, dated May 12, 1999. This SB 
describes procedures for inspecting the two headrest bushings for 
proper installation and installing Mecanindus pins to secure the 
bushings. The DGAC classified this SB as mandatory and issued 
airworthiness directive 2000-042(AB), dated January 26, 2000, in order 
to ensure the airworthiness of these third occupant seats in France.

FAA's Determination and Requirements of the Proposed AD

    These cabin attendant seats, manufactured in France, are used in 
airplanes that are type-certificated for operation in the United States 
under the provisions of section 21.29 of the Federal Aviation 
Regulations (14 CFR 21.29) and the applicable bilateral

[[Page 10454]]

airworthiness agreement. In keeping with this bilateral airworthiness 
agreement, the DGAC kept us informed of the situation described above. 
We have examined the DGAC's findings, reviewed all available 
information, and determined that AD action is necessary for products of 
this type design that are certificated for operation in the United 
States. For this reason, we are proposing this AD, which would require 
inspecting the two headrest bushings for proper installation and 
installing Mecanindus pins to secure the bushings. The proposed AD 
would require you to use the service information described previously 
to perform these actions.

Costs of Compliance

    About 459 Sicma Aero Seat third occupant attendant seat assemblies, 
133 Series, of the affected design are installed on 698 airplanes of 
U.S. registry. We estimate that it would take about 0.5 hour per seat 
assembly to perform the proposed actions, and that the average labor 
rate is $65 per work hour. The Mecanindus pins cost $99.88 each, 
however, Sicma has advised us that they will supply the parts at no 
cost. Based on the labor rate to install the parts, the total cost of 
the proposed AD to U.S. operators would be about $14,918.

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 above, I certify that the 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); and
    3. Would 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 proposed AD. See the ADDRESSES section for a location 
to examine the regulatory evaluation.

Bulletin 133-25-006, dated May 12, 1999, to perform the visual 
inspection and install the pins.
