14 CFR Part 39

[Docket No. FAA-2005-22876; Directorate Identifier 2005-NE-39-AD; 
Amendment 39-14734; AD 2006-17-13]
RIN 2120-AA64


Airworthiness Directives; RECARO Aircraft Seating GmbH & Co. 
(RECARO) Model 3410 Seats

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain RECARO Model 3410 302, 303, 306, 307, 314, 316, 317, 791, 792, 
and 795 series seats. This AD requires replacing the existing 
attachment bolts for the seat belts with longer attachment bolts. This 
AD results from a report of short attachment bolts that don't allow 
enough thread to properly secure the locknuts. We are issuing this AD 
to prevent a seat belt from detaching due to a loose locknut and 
attachment bolt, which could result in injury to an occupant during 
emergency conditions.

DATES: This AD becomes effective September 27, 2006. The Director of 
the Federal Register approved the incorporation by reference of certain 
publications listed in the regulations as of September 27, 2006.

ADDRESSES: You can get the service information identified in this AD 
from RECARO Aircraft Seating GmbH & Co. K, Technical Publications, 
Daimlerstrasse 21, 74523 Schwebisch Hall, Germany; Telephone 49 791 503 
7183; fax 49 791 503 7220.
    You may examine the AD docket on the Internet at http://dms.dot.gov 
or in Room PL-401 on the plaza level of the Nassif Building, 400 
Seventh Street, SW., Washington, DC.

Boston Aircraft Certification Office, FAA, Engine & Propeller 
Directorate, 12 New England Executive Park, Burlington, MA 01803; 
telephone (781) 238-7161; fax (781) 238-7170.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed AD. The proposed AD applies to certain RECARO Model 
3410 302, 303, 306, 307, 314, 316, 317, 791, 792, and 795 series seats. 
We published the proposed AD in the Federal Register on February 8, 
2006 (71 FR 6420). That action proposed to require replacing the 
existing attachment bolts for the seat belts with longer attachment 
bolts.

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 Offices 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.
    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment received.
    One commenter, the Boeing Airplane Company, asks us to remove the 
737 aircraft minor model designator ``-200'' from the applicability of 
this AD. Boeing states that research of the configurations for all 
delivered Boeing 737-200 airplanes failed to reveal any of the affected 
seats installed on those airplanes. However, Boeing states that RECARO 
reported to Boeing that seats were installed in a 737-200 airplane. 
Boeing believes an operator installed the seats after production of the 
airplane. Boeing also has records of installing seats with the affected 
model numbers on 737-700 and 737-800 airplanes. Boeing states that 
those seats incorporate the longer bolts specified in RECARO service 
bulletin SB-No.: 3410-25MR477, Revision 3, dated May 17, 2004, and we 
should use the generic 737 designation without a minor model 
designator. We partially agree. This AD applies to the RECARO seat 
models identified in paragraph (c) of this AD.

[[Page 49327]]

We list the known airplane models that use these types of seats to help 
owners and operators to determine if their airplane might use these 
seats. Listing the minor model designators for the 737 airplanes that 
could use these seats will help operators determine if this AD might 
apply to them. We retained the -200 designation, and added the -700 and 
-800 designations to the ``used on but not limited to'' statement in 
the Applicability.

Conclusion

    We have carefully reviewed the available data, including the 
comment 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

    We estimate that this AD will affect 3,101 seats installed in 
airplanes of U.S. registry. We also estimate that it will take about 
0.10 work-hour per seat to perform the actions, and that the average 
labor rate is $65 per work-hour. Required parts will cost about $10 per 
seat. Based on these figures, we estimate the total cost of this AD to 
U.S. operators to be $51,166.

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.
