Airworthiness Directives; McDonnell Douglas Corporation Model DC-
10-30, DC-10-30F, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F,
and MD-10-30F Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Model DC-10-30, DC-10-30F, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-
10-40F, and MD-10-30F airplanes. This AD requires doing a one-time
inspection of the wire bundles to determine if wires touch the upper
surface of the center upper auxiliary fuel tank, and marking the
location if necessary; a one-time inspection for splices and damage of
all wire bundles routed above the center upper auxiliary fuel tank; a
one-time inspection for damage to the fuel vapor barrier seal and upper
surface of the center upper auxiliary fuel tank; and corrective
actions, if necessary. This AD also requires installing non-metallic
barrier/shield sleeving to the wire harnesses, new clamps, new
attaching hardware, and new extruded channels. This AD was prompted by
fuel system reviews conducted by the manufacturer. We are issuing this
AD to reduce the potential of ignition sources inside fuel tanks,
which, in combination with flammable fuel vapors, could result in fuel
tank explosions and consequent loss of the airplane.
DATES: This AD is effective November 9, 2010.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of November 9,
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
certain Model DC-10-30, DC-10-30F, DC-10-30F (KC-10A and KDC-10), DC-
10-40, DC-10-40F, and MD-10-30F airplanes. That NPRM was published in
the Federal Register on June 28, 2010 (75 FR 36579). That NPRM proposed
to require doing a one-time inspection of the wire bundles to determine
if wires touch the upper surface of the center upper auxiliary fuel
tank, and marking the location if necessary; a one-time inspection for
splices and damage of all wire bundles routed above the center upper
auxiliary fuel tank; a one-time inspection for damage to the fuel vapor
barrier seal and upper surface of the center upper auxiliary fuel tank;
and corrective actions, if necessary. That NPRM also proposed to
require installing non-metallic barrier/shield sleeving to the wire
harnesses, new clamps, new attaching hardware, and new extruded
channels.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comment received. FedEx supports the
NPRM.
Conclusion
We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting the
AD as proposed.
Costs of Compliance
We estimate that this AD affects 166 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

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.
