nonmetallic barrier/shield sleeving, new clamps, new attaching 
hardware, and a new extruded channel. This AD adds certain inspections 
and expands the applicability. This AD was prompted by the 
determination that it is necessary to require an inspection of the wire 
bundles for damage at certain center upper auxiliary fuel tank 
locations on certain airplanes. We are issuing this AD to address the 
unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2014-03-07, Amendment 39-17744 (79 FR 9392, 
February 19, 2014) (``AD 2014-03-07''). AD 2014-03-07 applied to 
certain The Boeing Company Model MD-11 and MD-11F airplanes. The NPRM 
published in the Federal Register on August 17, 2017 (82 FR 39062). The 
NPRM was prompted by the determination that it is necessary to require 
an inspection of the wire bundles for damage at certain center upper 
auxiliary fuel tank locations on certain airplanes. The NPRM proposed 
to continue to require inspecting certain locations of the wire bundles 
of the center upper auxiliary fuel tank for damage, and corrective 
action if necessary. The NPRM also proposed to continue to require 
installing nonmetallic barrier/shield sleeving, new clamps, new 
attaching hardware, and a new extruded channel. The NPRM proposed to 
add certain inspections and expand the applicability. We are issuing 
this AD to reduce the potential of ignition sources inside fuel tanks, 
which, in combination with flammable fuel vapors, could result in fuel 
tank explosions and consequent loss of the airplane.

[[Page 16195]]

Comments

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

Supportive Comments

    The Air Line Pilots Association, International and Boeing supported 
the content of the NPRM.

Request To Clarify NPRM Requirements

    FedEx Express (FedEx) asked that the requirements in the NPRM 
relative to the referenced service information be clarified. FedEx 
stated that Boeing Service Bulletin MD11-28-126 has been revised 6 
times, and its related AD has been superseded twice; therefore, the 
NPRM requirements are confusing. FedEx added that the NPRM might need 
to be re-written completely to clearly state what the new requirements 
are, since some operators have accomplished either the original issue 
or one or more of Revisions 1 through 5 of Boeing Service Bulletin 
MD11-28-126. FedEx stated that it has accomplished Boeing Service 
Bulletin MD11-28-126, Revision 4, dated November 29, 2011; and at the 
time those procedures were done, the FedEx fleet was classified as 
Group 1, Configuration 1, and Group 2, Configuration 1 airplanes 
because FedEx didn't accomplish prior revisions of the service 
information. FedEx noted that currently its airplanes are Group 1, 
Configuration 2, and Group 2, Configuration 2, because FedEx has 
accomplished prior revisions of Boeing Service Bulletin MD11-28-126 on 
its airplanes.
    We acknowledge the commenter's request and agree to clarify. The 
new requirements of this AD apply only to certain airplanes identified 
in Boeing Service Bulletin MD11-28-126, Revision 6, dated July 1, 2016. 
As noted by the commenter, for a given airplane, the group and 
configuration might have changed between Boeing Service Bulletin MD11-
28-126, Revision 4, dated November 29, 2011, and Boeing Service 
Bulletin MD11-28-126, Revision 6, dated July 1, 2016.
    Group 1, Configuration 1 airplanes in Boeing Service Bulletin MD11-
28-126, Revision 4, dated November 29, 2011, are defined as airplanes 
on which ``prior issues of this service bulletin'' have not been 
accomplished. If the actions specified in Boeing Service Bulletin MD11-
28-126, Revision 4, dated November 29, 2011, have been done on one of 
these airplanes, this airplane becomes a Group 1 Configuration 2 
airplane as defined in Boeing Service Bulletin MD11-28-126, Revision 6, 
dated July 1, 2016, (airplanes on which ``prior issues of this service 
bulletin'' have been accomplished). Therefore, for this airplane, the 
inspections specified in Boeing Service Bulletin MD11-28-126, Revision 
6, dated July 1, 2016, for its new configuration must be done.
    The inspections in paragraph (i) of this AD must be done for 
airplanes identified as Groups 1, 2, and 5, Configuration 2 airplanes 
in Boeing Service Bulletin MD11-28-126, Revision 6, dated July 1, 2016. 
For this configuration, Boeing Service Bulletin MD11-28-126, Revision 
6, dated July 1, 2016, adds certain work instructions that were not in 
Boeing Service Bulletin MD11-28-126, Revision 4, dated November 29, 
2011; or Boeing Service Bulletin MD11-28-126, Revision 5, dated July 
29, 2014. Therefore, we have not changed this AD in this regard.

Request To Clarify New Inspection Requirements

    FedEx asked that the new inspection requirements specified in the 
proposed AD be clarified. FedEx stated that the proposed AD would 
retain all requirements of AD 2014-03-07, and would add inspection 
requirements for certain airplanes, as well as expanding the 
applicability. FedEx noted that Boeing Service Bulletin MD11-28-126, 
Revision 6, dated July 1, 2016, adds new inspection requirements but 
does not specify that the inspection be done at additional locations, 
as indicated in the proposed AD. FedEx added that the work instructions 
specified in Revisions 4 and 6 of Boeing Service Bulletin MD11-28-126 
are for the same area, so it is not clear which additional locations 
are mandated by the proposed AD.
    We agree to clarify. Boeing Service Bulletin MD11-28-126, Revision 
6, dated July 1, 2016, adds an inspection to determine if the wire 
bundles routed above the center upper auxiliary fuel tank between floor 
beams touch the upper surface of the tank for Groups 1, 2, and 5, 
Configuration 2 airplanes. We acknowledge that the phrase ``additional 
locations'' is unclear, and we have revised paragraph (i)(1) of this AD 
to state ``Do a general visual inspection of the wire bundles at the 
applicable center upper auxiliary fuel tank locations . . .'' Boeing 
Service Bulletin MD11-28-126, Revision 6, dated July 1, 2016, 
identifies the applicable inspection areas.

Request To Specify Airplane Configuration

    FedEx asked that the airplane configurations specified in the 
proposed AD be clarified. FedEx stated that paragraph (i) of the 
proposed AD specifies the following: ``For Groups 1, 2, and 5 
Configuration 2 airplanes, as identified in Boeing Service Bulletin 
MD11-28-126, Revision 6, dated July 1, 2016.'' FedEx added that, as 
defined in Boeing Service Bulletin MD11-28-126, Revision 6, dated July 
1, 2016, the FedEx fleet will be Group 1, Configuration 2 and Group 2, 
Configuration 2 airplanes because FedEx has accomplished a prior 
revision of this service information. FedEx believes its fleet should 
be in Group 1, Configuration 1, and Group 2, Configuration 1, but 
stated that it is not clear which airplanes are in which groups and 
configurations.
    We acknowledge the commenter's request and provide the following 
clarification. Paragraph 1.A., ``Effectivity'' of Boeing Service 
Bulletin MD11-28-126, Revision 6, dated July 1, 2016, specifies that 
airplanes on which previous issues of the service information have been 
done are identified as Configuration 2 airplanes. Therefore, any 
airplanes on which any previous issue of the service information was 
accomplished would be classified as Configuration 2. We have not 
changed this AD in this regard.

Request for Credit for Previous Actions Accomplished

    FedEx and United Parcel Service (UPS) requested credit for previous 
accomplishment of the actions in paragraphs (i)(1) and (i)(2) of the 
proposed AD using Boeing Service Bulletin MD11-28-126, Revision 4, 
dated November 29, 2011.
    FedEx stated that new inspections and corrective actions as 
specified in paragraphs (i)(1) and (i)(2) of the proposed AD were 
already performed by FedEx per Boeing Service Bulletin MD11-28-126, 
Revision 4, dated November 29, 2011, and should not be performed again. 
FedEx believes the proposed AD should give credit for work accomplished 
under Boeing Service Bulletin MD11-28-126, Revision 4, dated November 
29, 2011.
    UPS stated that prior accomplishment of Boeing Service Bulletin 
MD11-28-126, Revision 4, dated November 29, 2011, for Groups 1 and 2, 
Configuration 1 freighter aircraft meets the requirements of Boeing 
Service Bulletin MD11-28-126, Revision 6, dated July 1, 2016. UPS 
stated that the additional steps added by Revisions 5 and 6 of

[[Page 16196]]

Boeing Service Bulletin MD11-28-126 are not applicable to airplanes in 
freighter configurations or have already been accomplished using Boeing 
Service Bulletin MD11-28-126, Revision 4, dated November 29, 2011. UPS 
added that no further actions should be required on those airplanes.
    We agree to clarify. As stated previously, Boeing Service Bulletin 
MD11-28-126, Revision 6, dated July 1, 2016, adds an inspection to 
determine if the wire bundles routed above the center upper auxiliary 
fuel tank between floor beams touch the upper surface of the tank for 
Groups 1, 2, and 5, Configuration 2 airplanes. This inspection was not 
included in Boeing Service Bulletin MD11-28-126, Revision 5, dated July 
29, 2014; nor any of the previous revisions of Boeing Service Bulletin 
MD11-28-126. In addition, for compliance with this AD, this inspection 
must be done before the detailed inspection specified in Boeing Service 
Bulletin MD11-28-126, Revision 6, dated July 1, 2016, for Groups 1, 2, 
and 5, Configuration 2 airplanes. However, under the provisions of 
paragraph (m) of this AD, we will consider requests for approval of 
alternative methods of compliance (AMOCs) if sufficient data are 
submitted to substantiate that the actions would provide an acceptable 
level of safety. We have not changed this AD in this regard.
    We also partially agree with the commenter. The new requirements in 
Boeing Service Bulletin MD11-28-126, Revision 6, dated July 1, 2016, do 
not apply to certain freighter airplanes. Freighter airplanes are 
included in the procedures for Groups 1 and 5, Configuration 2 
airplanes, but not for Group 2, Configuration 2 airplanes, as specified 
in Boeing Service Bulletin MD11-28-126, Revision 6, dated July 1, 2016. 
Only passenger airplanes are included in the procedures for Group 2, 
Configuration 2 airplanes in Boeing Service Bulletin MD11-28-126, 
Revision 6, dated July 1, 2016. Therefore, we have added ``as 
applicable'' to the introductory text to paragraph (i) of this AD to 
clarify that the actions in paragraphs (i)(1) and (i)(2) of this AD 
apply to Groups 1 and 5, Configuration 2 airplanes, and passenger 
airplanes in Group 2, Configuration 2.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this 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 for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Service Bulletin MD11-28-126, Revision 6, dated 
July 1, 2016. This service information describes procedures for 
inspecting certain wire bundles of the center auxiliary fuel tank for 
damage, and repairing or replacing damaged wires. This service 
information also describes procedures for installing barrier/shield 
sleeving, clamping, and an extruded channel. This service information 
is reasonably available because the interested parties have access to

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

[[Page 16197]]

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.
