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, and MD-10-30F Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to 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, and DC-10-40F 
airplanes. That AD currently requires installing or replacing with 
improved parts, as applicable, the bonding straps between the metallic 
frame of the fillet and the wing leading edge ribs, on both the left 
and right sides of the airplane. This new AD revises the applicability 
by adding and removing certain airplanes. This new AD requires, for 
certain airplanes, repositioning or replacing two bonding straps, and 
doing a bonding-resistance check and an inspection to determine correct 
installation of certain bonding straps, and applicable corrective 
actions. This AD results from fuel system reviews conducted by the 
manufacturer. We are issuing this AD to reduce the potential of 
ignition sources inside fuel tanks in the event of a severe lightning 
strike, which, in combination with flammable fuel vapors, could result 
in fuel tank explosions and consequent loss of the airplane.

DATES: This AD becomes effective February 4, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of February 4, 
2010.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a second supplemental notice of proposed rulemaking 
(NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 
2006-16-03, Amendment 39-14703 (71 FR 43962, August 3, 2006). The 
existing AD applies to 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, and DC-10-40F 
airplanes. The existing AD requires installing or replacing with 
improved parts, as applicable, the bonding straps between the metallic 
frame of the fillet and the wing leading edge ribs, on both the left 
and right sides of the airplane. That second supplemental NPRM was 
published in the Federal Register on September 1, 2009 (74 FR 45135). 
That second supplemental NPRM proposed to add a requirement to 
reposition or replace bonding straps for certain airplanes, and for 
certain airplanes, a bonding-resistance check and an inspection to 
determine correct installation of certain bonding straps, and 
applicable corrective actions. The second supplemental NPRM also 
proposed to revise the applicability by adding and removing certain 
airplanes.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments from the sole 
commenter, FedEx, that have been received on the second supplemental 
NPRM.

Request for Credit for Actions Previously Accomplished

    FedEx requests credit for the actions previously accomplished. 
FedEx notes that under its alternative method of compliance (AMOC) 
previously approved by the FAA it has already accomplished resistance 
checks required by paragraphs (i)(2) and (j)(2) of the second 
supplemental NPRM on its airplanes. FedEx notes that they performed 
resistance checks in accordance with the AMOC previously granted by the 
FAA. FedEx states that it will accomplish a resistance check of any 
bonding straps replaced.
    FedEx also requests credit for correctly installing the braided 
bonding straps mentioned in paragraph (j)(1) of the second supplemental 
NPRM, which it accomplished in accordance with the AMOC previously 
granted.
    We agree to provide credit for accomplishing the actions required 
by paragraphs (i)(2), (j)(1), and (j)(2) of this final rule for the 
reasons that the commenter provided. Paragraph (l)(3) of the second 
supplemental NPRM already states that AMOCs approved previously in 
accordance with AD 2006-16-03 are approved as AMOCs for the 
corresponding provisions of this AD. Therefore, no change to this final 
rule is necessary.

Request To Change Applicability of Paragraph (h) of the Second 
Supplemental NPRM

    FedEx requests that we change the identification of airplanes 
subject to paragraph (h) of the second supplemental NPRM. FedEx notes 
that paragraph (h) of the second supplemental NPRM specifies 
``airplanes with fuselage numbers not identified in Table 2 of this AD 
except for airplanes identified in paragraph (i) or (j) of this AD.'' 
FedEx notes that its fuselage 317 does not appear in the effectivity of 
either Boeing Service Bulletin DC10-53-111, Revision 6, dated March 3, 
2009; or Boeing Service Bulletin DC10-53-109, Revision 7, dated March 
3, 2009 (the airplane groups identified in those service bulletins are 
referenced in paragraphs (i) and (j) of this AD). FedEx assumes that 
paragraph (h) was added to address this airplane and other airplanes 
that did not appear in either service bulletin. FedEx notes that the 
effectivity issues as they pertained to its fleet were sorted out in 
its AMOC request.
    We disagree that it is necessary to address fuselage number 317 and 
the other airplane fuselage numbers in this final rule because the 
effectivity has been corrected in the effectivity sections

[[Page 69269]]

of the Boeing service bulletins listed in Table 1 of this AD and/or 
previously approved AMOCs. We have not changed the AD in regard to this 
issue.

Request To Revise Paragraph (h) of the Second Supplemental NPRM

    FedEx requests that we remove the phrase ``and reposition two 
bonding straps'' from paragraph (h) of the second supplemental NPRM. 
FedEx states that if airplanes have not been modified to comply with 
the intent of the applicable service bulletin referenced in paragraph 
(h) of the second supplemental NPRM, then they would not have any 
bonding straps that require only repositioning.
    We agree to remove the phrase ``and reposition two bonding straps'' 
from paragraph (h) of the second supplemental NPRM in this final rule 
for the reason stated by the commenter.

Request To Clarify Paragraph (j)(1) of the Second Supplemental NPRM

    FedEx requests that we clarify paragraph (j)(1) of the second 
supplemental NPRM to help operators determine the correct braided 
bonding strap. FedEx suggests changing paragraph (j)(1) to state: ``Do 
a general visual inspection to verify correct installation of two 
braided bonding straps (one LH wing and one RH wing) as shown [in] 
Boeing Service Bulletin DC-10-53-111, Revision 6, Figure 3, Sheet 7 of 
9.''
    We agree that this change provides additional beneficial 
information to operators. We have revised paragraph (j)(1) of the final 
AD accordingly.

Request To Clarify Effectivity Sections of the Service Bulletins in 
Table 2

    FedEx requests that we note that the effectivity sections in the 
service bulletins identified in Table 2 of the second supplemental NPRM 
have 25 fuselage numbers that appear in both service bulletins. FedEx 
states that we may wish to address these fuselage numbers in some 
manner in the proposed rule.
    We agree that clarification may be necessary. Boeing has corrected 
Table 1 in the effectivity sections of the service bulletins referenced 
in Table 2 of this AD. We have not changed this AD in this regard.

Conclusion

    We have carefully reviewed the available data, including the 
comments that have been received, and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously. We have determined that these changes will neither increase 
the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    There are about 457 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs for 
U.S. operators 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); 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
