the NRC rules on compatibility and the
potential effect on interstate commerce.
Therefore, the petitioner requests that
NRC consider adopting the use of GPS
tracking as a national requirement for
mobile or portable uses of highly
radioactive sources. The petitioner
further notes that a possible alterative
would be to grant states the flexibility
to impose more stringent requirements
than those required under current NRC
regulations.
The petitioner acknowledges that
requiring a GPS on these vehicles does
not ensure that the radiological source
will be found. However, the petitioner
believes that these suggestions would
give law enforcement a significant
advantage.

SUMMARY: We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
AD results from mandatory continuing
airworthiness information (MCAI)
issued by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
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.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new
process for streamlining the issuance of
ADs related to MCAI. This streamlined
process will allow us to adopt MCAI
safety requirements in a more efficient
manner and will reduce safety risks to
the public. This process continues to
follow all FAA AD issuance processes to
meet legal, economic, Administrative
Procedure Act, and Federal Register
requirements. We also continue to meet
our technical decision-making
responsibilities to identify and correct
unsafe conditions on U.S.-certificated
products.
This proposed AD references the
MCAI and related service information

Discussion
The Direction Generale De L’Aviation
Civile (DGAC), which is the aviation
authority for France, has issued French
Airworthiness Directive F–2005–135,
dated August 3, 2005, (EASA reference
number 2005–6123) (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
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.
You may obtain further information
by examining the MCAI in the AD
docket.
Relevant Service Information
SICMA Aero Seat has issued Service
Bulletin No. 50–25–210, dated June 27,
2005. The actions described in this
service information are intended to
correct the unsafe condition identified
in the MCAI.
FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
E:\FR\FM\27APP1.SGM
27APP1
20964
Federal Register / Vol. 72, No. 81 / Friday April 27, 2007 / Proposed Rules
in the United States. Pursuant to our
bilateral agreement with this State of
Design Authority, they have notified us
of the unsafe condition described in the
MCAI and service information reference
above. We are proposing this AD
because we evaluated all information
provided by the State of Design
Authority and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the proposed AD is clear for
U.S. operators and is enforceable. In
making these changes, we do not intend
to differ substantively from the
information provided in the MCAI and
related service information.
We might also have proposed
different actions in this proposed AD
from those in the MCAI in order to
follow FAA policies. Any such
differences are described in a separate
paragraph of the proposed AD. These
requirements, if ultimately adopted, will
take precedence over the actions copied
from the MCAI.
cprice-sewell on PROD1PC66 with PROPOSALS
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 16,108 seats on airplanes of
U.S. registry. We also estimate that it
would take about .33 work-hours per
product to comply with this proposed
AD. The average labor rate is $80 per
work-hour. Required parts would cost
about $3,475 per seat. Based on these
figures, we estimate the cost of the
proposed AD on U.S. operators to be
$56,400,551, or $3,501 per seat.
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
VerDate Aug<31>2005
15:13 Apr 26, 2007
Jkt 211001
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 this 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. 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 proposed AD and placed it in the
AD docket.

We might also have proposed different actions in this proposed AD
from those in the MCAI in order to follow FAA policies. Any such
differences are described in a separate paragraph of the proposed AD.
These requirements, if ultimately adopted, will take precedence over
the actions copied from the MCAI.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 16,108 seats on airplanes of U.S. registry. We also
estimate that it would take about .33 work-hours per product to comply
with this proposed AD. The average labor rate is $80 per work-hour.
Required parts would cost about $3,475 per seat. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $56,400,551, or $3,501 per seat.
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 this 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. 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 proposed AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD.
SICMA Aero Seat: Docket No. FAA-2007-27519; Directorate Identifier
2007-NE-09-AD.
Comments Due Date
(a) We must receive comments by May 29, 2007.

Reason
(d) Direction General De L' Aviation Civile (DGAC) Airworthiness
Directive F-2005-135, dated August 3, 2005, states:
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 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.
Actions and Compliance
(e) Unless already done, within six months from the effective
date of this AD, identify the seats part numbers listed in the Table
1 of this AD and replace installed reading lights electrical power
supplies with new ones using the instructions of the SICMA Aero Seat
Service Bulletin No. 50-25-210, dated June 27, 2005.
FAA AD Differences
(f) None.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Boston Aircraft Certification Office, FAA, has the authority to
approve AMOCs for this AD, if requested using the procedures found
in 14 CFR 39.19.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, under the provisions of the Paperwork Reduction Act, the
Office of Management and Budget (OMB) has approved the information
collection requirements and has assigned OMB Control Number 2120-
0056.
