Airworthiness Directives; McDonnell Douglas Corporation Model DC-
10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), 
DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and 
KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F 
airplanes. This AD requires installing an in-line fuse in certain float 
level switches and sleeving the wires between the fuel tank and the in-
line fuse. For certain airplanes, this AD also requires installing an 
in-line fuse in certain fuel pump pressure switches. This AD results 
from fuel system reviews conducted by the manufacturer. We are issuing 
this AD to prevent fuel tank explosions and consequent loss of the 
airplane.

DATES: This AD is effective November 5, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of November 5, 
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-10-10, DC-10-10F,

[[Page 60603]]

DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, 
MD-10-10F, MD-10-30F, MD-11, and MD-11F airplanes. That NPRM was 
published in the Federal Register on April 21, 2010 (75 FR 20790). That 
NPRM proposed to require installing an in-line fuse in certain float 
level switches and sleeving the wires between the fuel tank and the in-
line fuse. For certain airplanes, that NPRM also proposed to require 
installing an in-line fuse in certain fuel pump pressure switches.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Request To Reference Information Notices or Revise Service Bulletin

    FedEx requested that Boeing Service Bulletin Information Notices 
(IN) MD11-28-132 IN 01, dated December 3, 2008; MD11-28-132 IN 02, 
dated March 18, 2010; and MD11-28-132 IN 03, dated March 25, 2010; be 
referenced in the NPRM as an approved deviation from Boeing Service 
Bulletin MD11-28-132, dated November 25, 2008, or that Boeing revise 
that service bulletin to incorporate the changes outlined in those INs. 
FedEx stated that, as the NPRM is written, the compliance requirements 
will prevent FedEx from complying with the NPRM unless an alternative 
method of compliance (AMOC) is granted.
    We partially agree. Since the issuance of the NPRM, Boeing has 
issued Service Bulletin MD11-28-132, Revision 1, dated July 6, 2010, to 
incorporate the changes outlined in Boeing Service Bulletin INs MD11-
28-132 IN 01, dated December 3, 2008; MD11-28-132 IN 02, dated March 
18, 2010; and MD11-28-132 IN 03, dated March 25, 2010. The revised 
service bulletin has only editorial changes with no additional work 
required. We have changed this AD to reference Boeing Service Bulletin 
MD11-28-132, Revision 1, dated July 6, 2010, in paragraphs (c)(2) and 
(g)(2) of this AD.
    We have also added paragraph (i) to this AD to give credit for 
actions done before the effective date of this AD in accordance with 
Boeing Service Bulletin MD11-28-132, dated November 25, 2008.

Additional Change Made to This AD

    We have revised paragraph (g)(1) of this AD to refer to Boeing 
Service Bulletin DC10-28-252, Revision 1, dated January 6, 2010, which 
describes editorial changes, but no new actions. We have added 
paragraph (h) to this AD to give credit for actions done before the 
effective date of this AD in accordance with Boeing Service Bulletin 
DC10-28-252, dated November 25, 2008.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the changes described previously. We also determined that these 
changes will not increase the economic burden on any operator or 
increase the scope of the AD.

Costs of Compliance

    We estimate that this AD will affect 281 airplanes of U.S. 
registry. The following table provides the estimated costs for U.S. 
operators 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), 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.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.
