14 CFR Part 39

[Docket No. FAA-2005-20848; Directorate Identifier 2005-NE-02-AD;
Amendment 39-14323; AD 2005-20-26]
RIN 2120-AA64

Airworthiness Directives; Aviointeriors S.p.A. (formerly ALVEN),
Series 312 Box Mounted Seats

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
Aviointeriors S.p.A. (formerly ALVEN), series 312 box mounted seats.
This AD requires initial and repetitive inspections of the seat
attachments for cracks, and if necessary, replacing the attachments.
This AD results from 10 reports of cracked attachments of series 312
box mounted seats. We are issuing this AD to prevent series 312 box
mounted seats from detaching from the passenger compartment floor,
which could result in injury to the occupant of the seat, and prevent
evacuation of passengers in the event of an emergency.

DATES: This AD becomes effective November 16, 2005. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of November 16, 2005.

ADDRESSES: Contact Aviointeriors S.p.A., Via Appia Km. 66.4--04013
Latina, Italy; telephone: 39-0773-6891; fax: 39-0773-631546 for the
service information identified in this AD.
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.

FOR FURTHER INFORMATION CONTACT: Jeffrey Lee, Aerospace Engineer,
Boston Aircraft Certification Office, FAA, Engine and Propeller
Directorate, 12 New England Executive Park, Burlington, MA 01803-5299;
telephone: 781-238-7161; fax: 781-238-7170.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed airworthiness directive (AD). The proposed AD applies
to Aviointeriors S.p.A. (formerly ALVEN), series 312 box mounted seats.
We published the proposed AD in the Federal Register on April 11, 2005
(70 FR 18322). That action proposed to require initial and repetitive
inspections of the seat attachments for cracks, and if necessary,
replacing the attachments.

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.

Comments

We provided the public the opportunity to participate in the
development of this AD. We received no comments on the proposal or on
the determination of the cost to the public.

Conclusion

We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

There are about 68 Aviointeriors S.p.A. series 312 box mounted
seats installed on airplanes of U.S. registry that are affected by this
AD. We estimate that it will take about 0.5 work hour per seat to
perform the inspections, and about 0.5 work hour per seat to perform
the replacement of an attachment. The average labor rate is $65 per
work hour. Required parts will cost about $297.50 per seat. Based on
these figures, we estimate the total cost of one inspection and total
parts replacement to U.S. operators to be $24,650.

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.
