Federal Register/Vol. 75, No. 226/Wednesday, November 24, 2010/Rules and Regulations 71529

47247). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
A design review has shown that the
Lightning Sensor System (LSS) antenna
which is optionally installed on certain
Falcon 7X aeroplanes might, in the event of
belly or gear-up landing, puncture the rear
fuel tank, which could result in fuel leakage
and post-landing fire.
This AD requires the reinforcement of the
rear fuel tank by bonding a titanium shield
plate on the tank structure above the LSS
antenna connector.
You may obtain further information by
examining the MCAI in the AD docket.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
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 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 required different
actions in this AD from those in the
MCAI in order to follow our FAA
policies. Any such differences are
highlighted in a Note within the AD.
Costs of Compliance
We estimate that this AD will affect 5
products of U.S. registry. We also
estimate that it will take about 10 work-
hours per product to comply with the
basic requirements of this AD. The
average labor rate is $85 per work-hour.
Required parts will cost about $384 per
product. Where the service information
lists required parts costs that are
covered under warranty, we have
assumed that there will be no charge for
these parts. As we do not control
warranty coverage for affected parties,
some parties may incur costs higher
than estimated here. Based on these
figures, we estimate the cost of this AD
to the U.S. operators to be $6,170, or

$1,234 per product.

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 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.
Examining the AD Docket
You may examine the AD docket on
the Internet at http://
www.regulations.gov; or in person at the
Docket Operations office between 9 a.m.
and 5 p.m., Monday through Friday,
except Federal holidays. The AD docket
contains the NPRM, the regulatory
evaluation, any comments received, and
other information. The street address for
the Docket Operations office (telephone
(800) 647-5527) is in the ADDRESSES
section. Comments will be available in

the AD docket shortly after receipt.
