Federal Register Abstract
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.

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
--------------------------------------------------------------------------------------------------------------------------------------------------------
Number of U.S.-
Work hours Average labor rate Parts Cost per airplane registered Fleet cost
per hour airplanes
--------------------------------------------------------------------------------------------------------------------------------------------------------
2-17........................ $80 Up to $4,169........... Up to $5,529.......... 281 Up to $1,553,649.
--------------------------------------------------------------------------------------------------------------------------------------------------------
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.
