SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD requires installing a support bracket
and coupler on the left and right wing-to-fuselage transition, and
metallic overbraid on the left and right leading edge wire assembly.
This AD was prompted by fuel system reviews conducted by the
manufacturer, as well as reports that the fuel quantity system was
affected by lightning-induced transients. We are issuing this AD to
prevent lightning-induced transients to the fuel quantity indication
system, which could cause voltage levels to go beyond original design
levels between fuel tank probes and structure, and become a potential
ignition source at the fuel tank, which, in combination with flammable
fuel vapors, could result in a fuel tank explosion and consequent loss
of the airplane.
DATES: This AD is effective November 18, 2010.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of November 18,
2010.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness directive (AD) that would apply to
the specified products. That NPRM was published in the Federal Register
on July 7, 2010 (75 FR 38943). That NPRM proposed to require installing
a support bracket and coupler on the left and right wing-to-fuselage
transition, and metallic overbraid on the left and right leading edge
wire assembly.
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 relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 61 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Installation...................... 28 work-hours x $85 per $999 $3,379 $206,119
hour = $2,380.
----------------------------------------------------------------------------------------------------------------
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
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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.

manufacturer. The Federal Aviation Administration is issuing this AD
to prevent lightning-induced transients to the fuel quantity
indication system, which could cause voltage levels to go beyond
original design levels between fuel tank probes and structure and

Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Installation
(g) Within 60 months after the effective date of this AD,
install a support bracket and coupler on the left and right wing-to-
fuselage transition, and metallic overbraid on the left and right
leading edge wire assembly, in accordance with the Accomplishment
Instructions of Boeing Service Bulletin DC10-28-262, Revision 1,
dated June 9, 2010.
Installation According to Previous Issue of Service Bulletin
(h) Installing a support bracket and coupler on the left and
right wing-to-fuselage transition, and metallic overbraid on the
left and right leading edge wire assembly, is also acceptable for
compliance with the requirements of paragraph (g) of this AD if done
before the effective date of this AD in accordance with the
Accomplishment Instructions of Boeing Service Bulletin DC10-28-262,
dated January 6, 2010.
