Airworthiness Directives; The Boeing Company 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; Model MD-10-10F, MD-10-30F, MD-11, and MD-11F Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for the products listed above. That AD currently requires an inspection 
to determine if a certain fuel pump housing electrical connector is 
installed. The existing AD also requires a revision to the FAA-approved 
airplane flight manual (AFM) to advise the flightcrew of the 
appropriate procedures for disabling certain fuel pump electrical 
circuits following failure of a fuel pump housing electrical connector 
if applicable. The existing AD also requires the deactivation of 
certain fuel tanks or fuel pumps and the installation of placards if 
applicable. The existing AD allows the optional replacement of the fuel 
pump housing electrical connectors with new, improved parts, which 
would terminate the AFM revisions, deactivation of certain fuel tanks 
and fuel pumps, and placard installation. This new AD instead requires 
replacing the fuel pump housing electrical connector assembly with a 
new part and doing repetitive inspections for continuity, resistance, 
and insulation resistance, and doing corrective actions if necessary. 
This AD was prompted by reports of failures of a certain fuel pump 
housing electrical connector. We are issuing this AD to detect and 
correct insulation resistance degradation and arcing in the potted 
backside of the electrical connector assembly of the fuel boost/
transfer pump housing, which could compromise its performance and cause 
an ignition source in the fuel tank, resulting in a fuel tank explosion 
and consequent loss of the airplane.

DATES: This AD is effective July 6, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of July 6, 2011.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede airworthiness directive (AD) 2007-15-05, amendment 
39-15134 (72 FR 40216, July 24, 2007). That AD applies to the specified 
products. The NPRM published in the Federal Register on November 5, 
2010 (75 FR 68246). That NPRM proposed to require replacing the fuel 
pump housing electrical assembly with a new part and doing repetitive 
inspections for continuity, resistance, and insulation resistance, and 
doing corrective actions, if necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
and the FAA's response to each comment.

Request for Addition of Part Number

    FedEx requested that we add, in the header above the Summary and 
paragraphs (c), (e), and (f) of the proposed AD, the part number of the 
fuel pump housing electrical connector assembly requiring replacement. 
FedEx stated that the change will clarify the AD and avoid unnecessary 
work and cost to the operators.
    We partially agree with the commenter. We disagree with adding the 
part number of the fuel pump housing electrical connector assembly 
requiring replacement to the header information, paragraph (c), and 
paragraph (f) of this AD because the affected part could be rotated 
onto any of the airplanes listed in the applicability. However, we 
agree that clarification of paragraph (h) of this AD (referred to as 
paragraph (g) in the NPRM) is needed. In order to comply with this AD, 
for all airplanes in the applicability it must be determined if the 
fuel pump housing electrical connector assembly having part number (P/
N) 60-84355-1 is installed. We have added paragraph (g) to specify the 
inspection to determine the part number. We have also added a reference 
of P/N 60-84355-1 to paragraph (h) of this AD for clarification. In 
addition, we have added a reference of P/N 60-84355-1 to paragraph (e) 
of this AD for clarification.

[[Page 31463]]

Clarification of Paragraph (i) of This AD

    We have revised paragraph (i) of this AD by replacing the phrase, 
``replacing the fuel pump electrical connector assembly as required by 
paragraph (g) of this AD'' with the phrase, ``installing the fuel pump 
housing electrical connector assembly having P/N 60-84351, in 
accordance with Boeing Alert Service Bulletin DC10-28A261 or Boeing 
Alert Service Bulletin MD11-28A143,'' to clarify that P/N 60-84351 must 
be repetitively inspected after installation.

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 change described previously--and 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.
    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 affects 281 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                                     Estimated Costs

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

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 have 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 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.
