Airworthiness Directives; SICMA Aero

Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
AGENCY:
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from Mandatory Continuing
Airworthiness Information (MCAI)
provided by the aviation authority of
France to identify and correct an unsafe
condition on SICMA Aero Seat 50XXX
Passenger Seats. The MCAI states the
following:
A release of smoke was experienced in the
passenger compartment during flight after an
overheating of a reading lights power box of
a PN 5039201–4T SICMA seat. An analysis
put into evidence that this overheating was
caused by a short-circuit produced by the
rupture of an electrical power supply
component (PN 78147–B). It has been noticed
that this power supply is not in compliance
with DO 160 environmental standard.
The short-circuiting could result in
arcing and consequent smoke or fire. We
are proposing this AD to prevent a
short-circuit in the power box, which
could result in smoke or fire in the
airplane cabin.
DATES: This AD becomes effective
October 26, 2007. The Director of the
Federal Register approved the
incorporation by reference of certain
publications listed in this AD as of
October 26, 2007.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on April 27, 2007 (72 FR
20963). That NPRM proposed to correct
an unsafe condition for the specified
products. The Direction Generale De
L’Aviation Civile (DGAC) AD states that:
A release of smoke was experienced in the
passenger compartment during flight after an
overheating of a reading lights power box of
a PN 5039201–4T SICMA seat. An analysis
put into evidence that this overheating was
caused by a short-circuit produced by the
rupture of an electrical power supply
component (PN 78147–B). It has been noticed
that this power supply is not in compliance
with DO 160 environmental standard.
The short-circuiting could result in
arcing and consequent smoke or fire.
We gave the public the opportunity to
participate in developing this AD. We
considered the comments received.
Request To Revise the Costs of
Compliance
SICMA Aero Seat requests us to
change the Costs of Compliance section
of the AD to accurately depict the extent
of the issue. SICMA has verified the
number of affected power boxes
installed in seats and the number
already retrofitted. SICMA states that
only 731 seats don’t comply with the
AD and we should change the Costs of
Compliance to reflect the new numbers.
We agree. We changed the Costs to
Comply to reflect the reduced number of
affected seats.
Conclusion
We reviewed the available data,
including the comment[s] received, and
determined that air safety and the
public interest require adopting the AD
with the changes described previously.
We determined that these changes will
not increase the economic burden on
any operator or increase the scope of the
AD.
Costs of Compliance
We estimate that this AD will affect
about 731 seats installed on airplanes of

U.S. registry. We also estimate that it
would take about 0.33 work-hour to
perform the actions required by this AD
and that the average labor rate is $80 per
work-hour. Required parts will cost
about $3,475 per seat. Based on these
figures, we estimate the total cost of this
AD to U.S. operators to be $2,559,523.
Our cost estimate is exclusive of
possible warranty coverage.
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 evaluation, any comments
received, and other information. The
street address for the Docket Operations
office (telephone (800) 647–5527) is

Comments will be available in the AD
docket shortly after receipt.

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.
These seats are installed on, but not limited
to, Boeing 747, 767, and 777 series, and
Airbus A330 and A340 series airplanes.
