ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for Sicma PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 75411 Aero Seat third occupant seat assemblies, 133 series. This AD requires visually inspecting the installation of the two headrest bushings and installing Mecanindus pins to secure the bushings. This 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 highenergy stop of the airplane, possibly injuring the seat occupant. We are issuing 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: This AD becomes effective January 19, 2007. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of January 19, 2007.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 with a proposed AD. The proposed AD applies to Sicma Aero Seat third occupant seat assemblies, 133 series. We published the proposed AD in the Federal Register on March 1, 2006 (71 FR 10453). That action proposed to require visually inspecting the installation of the two headrest bushings and installing Mecanindus pins to secure the bushings. Examining the AD Docket You may examine the docket that contains the AD, any comments received, and any final disposition in person at the Docket Management Facility Docket Office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

We have considered the comments received. economic burden on any operator nor increase the scope of the AD. Costs of Compliance Request To Change Compliance Requirement Air Transport Association and Northwest Airlines request that the compliance requirement of ‘‘within 30 days’’ be changed to ‘‘within 90 days’’. This will allow AD compliance in conjunction with operators’ current ACheck interval. We agree and changed the AD to ‘‘within 90 days’’. Labor Time Information Does Not Match the Sicma Aero Seat Service Bulletin Air Transport Association and Northwest Airlines state that the estimated labor time information in the proposed AD does not match the manpower estimate in Sicma Aero Seat Service Bulletin (SB) No. 133–25–006, dated May 12, 1999. We agree that the AD estimate for doing the work needs to match the SB. We changed the labor time in the AD to 0.17 work-hour (10 minutes) per seat. Seat Part Numbers Do Not Match Air Transport Association and Northwest Airlines state that the seat part numbers (P/Ns) in the proposed AD do not match those in Sicma Aero Seat SB No. 133–25–006, dated May 12, 1999. We partially agree. We corrected the P/Ns to 1330622–070, 1330622– 070–1, 1330622–070–2, 1330622–100, and 1330622V100–1 in the AD. These are the same listed P/Ns affected as those identified by the Direction Generale de L’Aviation Civile, which is the airworthiness authority of France. Question on Serial Numbers Air Transport Association and Northwest Airlines question why the serial numbers (SNs) in the proposed AD are specific, whereas there are no specific SNs listed in the SB. We listed the same SNs as those identified by the Direction Generale de L’Aviation Civile, which is the airworthiness authority for France. They correctly identified the SNs affected, in their AD No. 2000– 042(AB). We did not change the AD. cprice-sewell on PROD1PC66 with RULES Conclusion We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the VerDate Aug<31>2005 14:57 Dec 14, 2006 Jkt 211001 There are about 459 Sicma Aero Seat third occupant seat assemblies, 133 series, of the affected design installed on airplanes of U.S. registry. There are about 698 airplanes of U.S. registry that these seats can be installed on. We estimate that it will take about 0.17 work-hour per seat assembly to perform the actions, and that the average labor rate is $65 per work-hour. The Mecanindus pins cost $99.88 each, however, Sicma Aero Seat 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 AD to U.S. operators will be about $5,072. 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. We prepared a summary of the costs to comply with this AD and placed it in the AD Docket. You may get a copy of this summary at the address listed under ADDRESSES.

That NPRM was published in the Federal Register on August 21, 2006 (71 FR 48487). That NPRM proposed to require implementing a corrosion prevention and control program (CPCP) either by accomplishing specific tasks or by revising the maintenance inspection program to include a CPCP. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Request To Change Incorporation of Certain Information The Modification and Replacement Parts Association (MARPA) states that, typically, airworthiness directives are based on service information originating with the type certificate holder or its suppliers. MARPA adds that manufacturer service documents are privately authored instruments generally having copyright protection against duplication and distribution. MARPA notes that when a service document is incorporated by reference into a public document, such as an airworthiness directive, it loses its private, protected status and becomes a public document. MARPA adds that if a service document is used as a mandatory element of compliance, it should not simply be referenced, but should be incorporated into the regulatory document; by definition, public laws must be public, which means they cannot rely upon private writings. MARPA adds that incorporated by reference service documents should be made available to the public by publication in the Docket Management System (DMS), keyed to the action that incorporates them. MARPA notes that the stated purpose of the incorporation by reference method is brevity, to keep from expanding the Federal Register needlessly by publishing documents already in the hands of the affected E:\FR\FM\15DER1.SGM 15DER1

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

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
Sicma Aero Seat third occupant seat assemblies, 133 series. This AD 
requires visually inspecting the installation of the two headrest 
bushings and installing Mecanindus pins to secure the bushings. This 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 issuing 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: This AD becomes effective January 19, 2007. The Director of the 
Federal Register approved the incorporation by reference of certain 
publications listed in the regulations as of January 19, 2007.

ADDRESSES: You can get the service information identified in this AD

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed AD. The proposed AD applies to Sicma Aero Seat third 
occupant seat assemblies, 133 series. We published the proposed AD in 
the Federal Register on March 1, 2006 (71 FR 10453). That action 
proposed to require visually inspecting the installation of the two 
headrest bushings and installing Mecanindus pins to secure the 
bushings.

Examining the AD Docket

    You may examine the docket that contains the AD, any comments 
received, and any final disposition in person at the Docket Management 
Facility Docket Office between 9 a.m. and 5 p.m., Monday through 
Friday, except Federal holidays. The Docket Office (telephone (800) 
647-5227) is located on the plaza level of the Department of 
Transportation Nassif Building at the street address stated in 
ADDRESSES. Comments will be available in the AD docket shortly after 
the DMS receives them.

[[Page 75412]]

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Request To Change Compliance Requirement

    Air Transport Association and Northwest Airlines request that the 
compliance requirement of ``within 30 days'' be changed to ``within 90 
days''. This will allow AD compliance in conjunction with operators' 
current A-Check interval. We agree and changed the AD to ``within 90 
days''.

Labor Time Information Does Not Match the Sicma Aero Seat Service 
Bulletin

    Air Transport Association and Northwest Airlines state that the 
estimated labor time information in the proposed AD does not match the 
manpower estimate in Sicma Aero Seat Service Bulletin (SB) No. 133-25-
006, dated May 12, 1999. We agree that the AD estimate for doing the 
work needs to match the SB. We changed the labor time in the AD to 0.17 
work-hour (10 minutes) per seat.

Seat Part Numbers Do Not Match

    Air Transport Association and Northwest Airlines state that the 
seat part numbers (P/Ns) in the proposed AD do not match those in Sicma 
Aero Seat SB No. 133-25-006, dated May 12, 1999. We partially agree. We 
corrected the P/Ns to 1330622-070, 1330622-070-1, 1330622-070-2, 
1330622-100, and 1330622V100-1 in the AD. These are the same listed P/
Ns affected as those identified by the Direction Generale de L'Aviation 
Civile, which is the airworthiness authority of France.

Question on Serial Numbers

    Air Transport Association and Northwest Airlines question why the 
serial numbers (SNs) in the proposed AD are specific, whereas there are 
no specific SNs listed in the SB. We listed the same SNs as those 
identified by the Direction Generale de L'Aviation Civile, which is the 
airworthiness authority for France. They correctly identified the SNs 
affected, in their AD No. 2000-042(AB). We did not change the AD.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, and determined that air safety and the public 
interest require adopting the AD with the changes described previously. 
We have determined that these changes will neither increase the 
economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    There are about 459 Sicma Aero Seat third occupant seat assemblies, 
133 series, of the affected design installed on airplanes of U.S. 
registry. There are about 698 airplanes of U.S. registry that these 
seats can be installed on. We estimate that it will take about 0.17 
work-hour per seat assembly to perform the actions, and that the 
average labor rate is $65 per work-hour. The Mecanindus pins cost 
$99.88 each, however, Sicma Aero Seat 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 AD to U.S. operators will be about $5,072.

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 have 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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 summary of the costs to comply with this AD and 
placed it in the AD Docket. You may get a copy of this summary at the 
address listed under ADDRESSES.

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

    These third occupant seats are installed on, but not limited to, 
Airbus A319, A320, and A321 series airplanes.

Unsafe Condition

    (d) This 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 issuing 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.
