Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding an existing airworthiness directive (AD) for certain 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, MD-10-10F, and MD-10-30F 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; and for certain airplanes, repositioning or replacing two bonding straps, doing a bonding-resistance check and an inspection to determine correct installation of certain bonding straps, and applicable corrective actions. This new AD adds airplanes to the applicability and, depending on the airplane configuration, requires installing new braided bonding straps, inspecting to determine if a certain strap is installed and replacing with or installing a braided bonding strap if necessary, measuring the electrical resistance of the bonding straps, verifying that brackets have an acceptable fillet seal, and doing corrective actions if necessary. This AD
Page 59729
was prompted by fuel system reviews conducted by the manufacturer, and our determination that additional actions are necessary to address the identified unsafe condition. 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 is effective November 5, 2012.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of November 5, 2012.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2009-26-17, Amendment 39-16156 (74 FR 69268, December 31, 2009). That AD applies to the specified products. The NPRM published in the Federal Register on March 28, 2012 (77 FR 18719). That NPRM proposed to continue to require 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 NPRM also proposed to continue to require, for certain airplanes, repositioning or replacing two bonding straps, doing a bonding-resistance check and an inspection to determine correct installation of certain bonding straps, and applicable corrective actions. That NPRM also proposed to add airplanes to the applicability, and depending on the airplane configuration, installing new braided bonding straps, inspecting to determine if a certain strap is installed and replacing with or installing a braided bonding strap if necessary, measuring the electrical resistance of the bonding straps, verifying that brackets have an acceptable fillet seal, 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 (77 FR 18719, March 28, 2012) and the FAA's response to each comment.
Request To Add Credit for Previous Actions
FedEx requested that previous actions accomplished on 51 of its airplanes using Boeing Service Bulletin DC10-53-111, Revision 4, dated September 21, 2006; or Boeing Service Bulletin DC10-53-111, Revision 7, dated March 16, 2011; be acceptable as terminating action for the actions specified in paragraph (j) of the NPRM (77 FR 18719, March 28, 2012).
We partially agree. We agree that the actions are acceptable, but do not agree to change the AD. We disagree that credit for previous actions should be added to the AD. Paragraphs (m)(3) and (m)(4) of this AD already allow previous accomplishment of the actions specified in paragraphs (g), (h), (i), and (j) of this AD, if those actions were done using alternative methods of compliance (AMOCs) approved in accordance with AD 2006-16-03, Amendment 39-14703 (71 FR 43962, August 3, 2006); and AD 2009-26-17, Amendment 39-16156 (74 FR 69268, December 31, 2009). Boeing Service Bulletin DC10-53-111, Revision 4, dated September 21, 2006, states that it is approved as an AMOC for AD 2006-
16-03. We have not changed the final rule in this regard.
Request To Combine Paragraphs
FedEx suggested that paragraphs (l)(3) and (l)(4) of the NPRM (77 FR 18719, March 28, 2012) be combined since they state the same thing.
We do not agree to combine paragraphs (l)(3) and (l)(4) of this AD, because those paragraphs state different requirements for different airplanes. We have not changed the final rule in this regard.
Request To Correct Effectivity
FedEx stated that Boeing Service Bulletin DC10-53-111, Revision 7, dated March 16, 2011, incorrectly specifies that the reason for the revision was to add fuselage 317 to the effectivity of that service bulletin. FedEx stated that fuselage 317 was not and does not need to be added to the effectivity of that service bulletin, because fuselage 317 is in the effectivity of Boeing Service Bulletin DC10-53-109, Revision 8, dated March 10, 2011.
We infer that FedEx is requesting that Boeing Service Bulletin DC10-53-111, Revision 7, dated March 16, 2011, be revised to correct the discrepancy in the stated reason for the revision of that service bulletin. We do not agree. Boeing issued Service Bulletin Information Notice DC10-53-111 IN 02, dated June 17, 2011, to clarify that fuselage 317 was not added to the effectivity of Boeing Service Bulletin DC10-
53-111, Revision 7, dated March 16, 2011. No change to this final rule is necessary in this regard.
Explanation of Additional Changes Made To This AD
We have revised certain headings throughout this AD.
Conclusion
We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM (77 FR 18719, March 28, 2012) for correcting the unsafe condition; and
Page 59730
Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 18719, March 28, 2012).
Costs of Compliance
We estimate that this AD affects 208 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
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.
