[Docket No. FAA-2010-0553; Directorate Identifier 2010-NM-070-AD; 
Amendment 39-16448; AD 2010-20-13]
RIN 2120-AA64

 
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.
