SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2016-04-16, Amendment 39-18410 (81 FR 12806, 
March 11, 2016) (``AD 2016-04-16''). AD 2016-04-16 applied to all 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, MD-10-30F, MD-11, 
and MD-11F airplanes. The NPRM published in the Federal Register on 
June 14, 2018 (83 FR 27718). The NPRM was prompted by a fuel system 
review conducted by the manufacturer and a determination that 
accomplishing new service information in conjunction with certain 
service information specified in AD 2016-04-16 would terminate certain 
actions in related ADs. The NPRM proposed to continue to require adding 
design features to detect electrical faults and to detect a pump 
running in an empty fuel tank. The NPRM also proposed to provide 
optional terminating action for certain requirements. We are issuing 
this AD to address 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.

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.

Support for the NPRM

    FedEx Express (FedEx) and Air Line Pilots Association, 
International (ALPA) provided their concurrence with the NPRM. FedEx 
also pointed out that the NPRM affects 39 Model MD-10 airplanes and 57 
Model MD-11 airplanes in the FedEx fleet.

Request To Clarify the Terminating Action Specified in Paragraph (k) of 
the Proposed AD

    Boeing requested that we clarify the terminating action specified 
in paragraph (k) of the proposed AD. Boeing agreed that the repetitive 
inspections and tests may be terminated upon installation of the new 
connector design per the Boeing service bulletins cited in paragraph 
(k) of the proposed AD (Boeing Service Bulletin DC10-28-264, dated May 
15, 2015; and Boeing Service Bulletin MD11-28-146, dated May 15, 2015). 
Boeing noted that those service bulletins were approved by the Manager, 
Los Angeles ACO Branch. Boeing added that those service bulletins also 
specify an additional condition for the terminating actions: the fault 
current detectors cited in paragraphs (h)(1)(ii) and (h)(2)(ii) of the 
proposed AD must also be installed before the repetitive actions are 
terminated. Boeing recommended that paragraph (k) of the proposed AD be 
revised to clarify that the fault current detectors must be installed 
per paragraphs (h)(1)(ii) and (h)(2)(ii) of the proposed AD in order to 
accomplish the terminating action per the Boeing service bulletins 
cited in paragraph (k) of the proposed AD.
    We agree with the commenter's request. Paragraph F., ``Approval,'' 
of Boeing Service Bulletin DC10-28-264, dated May 15, 2015; and Boeing 
Service Bulletin MD11-28-146, dated May 15, 2015, specifies that the 
actions in those service bulletins as well as the service bulletins 
specified in paragraphs (h)(1)(ii) and (h)(2)(ii) of this AD terminate 
the actions required by paragraph (a) of AD 2002-13-10, Amendment 39-
12798 (67 FR 45053, July 8, 2002) (``AD 2002-13-10''), paragraph (a) of 
AD 2003-07-14, Amendment 39-13110 (68 FR 17544, April 10, 2003) (``AD 
2003-07-14''), and paragraph (j) of AD 2011-11-05, Amendment 39-16704 
(76 FR 31462, June 1, 2011) (``AD 2011-11-05''). We have revised 
paragraph (k) of this AD accordingly.

Request To Withdraw the NPRM

    United Parcel Service (UPS) requested that we withdraw the NPRM. 
UPS pointed out that the NPRM includes no

[[Page 55611]]

new requirements or information. UPS indicated that no new requirements 
or actions would create an undue burden on operators because existing 
internal paperwork and records must then be revised to provide proof of 
compliance.
    We acknowledge the commenter's concerns; however, we disagree with 
the request to withdraw the NPRM. AD 2003-07-14 was affected by AD 
2016-04-16 but was inadvertently left out of AD 2016-04-16. This AD 
corrects that oversight and includes AD 2003-07-14 as an affected AD. 
Additionally, this AD provides new optional terminating actions that 
affect AD 2003-07-14 as well as AD 2002-13-10 and AD 2011-11-05.

Request To Include Updated Service Information

    UPS requested that we revise the NPRM to include a later revision 
of Boeing Trijet Special Compliance Item Report MDC-02K1003. UPS 
pointed out that the new fuel pump housing assembly that is created by 
installation of the new connectors was not added until Revision N of 
Boeing Trijet Special Compliance Item Report MDC-02K1003. Additionally, 
UPS mentioned that Revision R of Boeing Trijet Special Compliance Item 
Report MDC-02K1003 was in the approval process at the time the comment 
was submitted.
    We agree with the request to include the latest published version 
of Boeing Trijet Special Compliance Item Report MDC-02K1003. We 
referred to Boeing Trijet Special Compliance Item Report MDC-02K1003, 
Revision M, including Appendices A through D, dated July 25, 2014, as 
an appropriate source of service information in the NPRM. Revision R of 
Boeing Trijet Special Compliance Item Report MDC-02K1003, including 
Appendices A through D, dated May 9, 2018, includes new part numbers 
for Critical Design Configuration Control Limitation (CDCCL) 28-2 and 
updates certain special compliance items to include additional 
procedures for airplanes with a certain configuration. We have added 
paragraph (l) to this AD to include Revision R of Boeing Trijet Special 
Compliance Item Report MDC-02K1003, including Appendices B through D, 
dated May 9, 2018, as an optional revision to paragraph (h)(3) of this 
AD, and we have redesignated subsequent paragraphs accordingly. We are 
considering further rulemaking to require revising the maintenance or 
inspection program to include Revision R of Boeing Trijet Special 
Compliance Item Report MDC-02K1003, including Appendices B through D, 
dated May 9, 2018.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes 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 addressing 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 this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed the following Boeing service information.
     Boeing Alert Service Bulletin DC10-28A253, dated June 5, 
2014; and Boeing Alert Service Bulletin MD11-28A133, dated June 5, 
2014. This service information describes procedures for replacing the 
fuel pump control relays with fault current detectors and changing the 
fuel tank boost/transfer pump wire termination. These documents are 
distinct since they apply to different airplane models.
     Boeing Service Bulletin DC10-28-256, dated June 24, 2014; 
and Boeing Service Bulletin MD11-28-137, dated June 24, 2014. This 
service information describes procedures for changing the fuel pump 
control and indication system wiring. These documents are distinct

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.

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.

flammable fuel vapors, could result in fuel tank explosions and 
consequent loss of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Restatement of Paragraph (g) of AD 2016-04-16, With No Changes

    This paragraph restates the requirements of paragraph (g) of AD 
2016-04-16, with no changes. Except as provided by paragraph (h) of 
this AD: As of 48 months after April 15, 2016 (the effective date of 
AD 2016-04-16), no person may operate any airplane affected by this 
AD unless an amended type certificate or supplemental type 
certificate that incorporates the design features and requirements 
described in paragraphs (g)(1) through (g)(4) of this AD has been 
approved by the Manager, Los Angeles ACO Branch, FAA, and those 
design features are installed on the airplane to meet the criteria 
specified in section 25.981(a) and (d) of the Federal Aviation 
Regulations (14 CFR 25.981(a) and (d), at Amendment 25-125 (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgFAR.nsf/0/339DAEE3E0A6379D862574CF00641951?OpenDocument)). For airplanes on 
which Boeing-installed auxiliary fuel tanks are

[[Page 55613]]

removed, the actions specified in this AD for the auxiliary fuel 
tanks are not required.
    (1) For all airplanes: Each electrically powered alternating 
current (AC) fuel pump installed in any fuel tank that normally 
empties during flight and each pump that is partially covered by a 
lowering fuel level--such as main tanks, center wing tanks, 
auxiliary fuel tanks installed by the airplane manufacturer, and 
tail tanks--must have a protective device installed to detect 
electrical faults that can cause arcing and burn through of the fuel 
pump housing and pump electrical connector. The same device must 
shut off the pump by automatically removing electrical power from 
the pump when such faults are detected. When a fuel pump is shut off 
resulting from detection of an electrical fault, the device must 
stay latched off, until the fault is cleared through maintenance 
action and the pump is verified safe for operation.
    (2) For airplanes with a 2-person flightcrew: Additional design 
features, if not originally installed by the airplane manufacturer, 
must be installed to meet 3 criteria: To detect a running fuel pump 
in a tank that is normally emptied during flight, to provide an 
indication to the flightcrew that the tank is empty, and to 
automatically shut off that fuel pump. The prospective pump 
indication and shutoff system must automatically shut off each pump 
in case the flightcrew does not shut off a pump running dry in an 
empty tank within 60 seconds after each fuel tank is emptied. An 
airplane flight manual supplement (AFMS) that includes flightcrew 
manual pump shutoff procedures in the Limitations section of the 
AFMS must be submitted to the Los Angeles ACO Branch, FAA, for 
approval.
    (3) For airplanes with a 3-person flightcrew: Additional design 
features, if not originally installed by the airplane manufacturer, 
must be installed to detect when a fuel pump in a tank that is 
normally emptied during flight is running in an empty fuel tank, and 
to provide an indication to the flightcrew that the tank is empty. 
The flight engineer must manually shut off each pump running dry in 
an empty tank within 60 seconds after the tank is emptied. The AFMS 
Limitations section must be revised to specify that this pump 
shutoff must be done by the flight engineer.
    (4) For all airplanes with tanks that normally empty during 
flight: Separate means must be provided to detect and shut off a 
pump that was previously commanded to be shut off automatically or 
manually but remained running in an empty tank during flight.

(h) Restatement of Paragraph (h) of AD 2016-04-16, With No Changes

    This paragraph restates the provisions of paragraph (h) of AD 
2016-04-16, with no changes. In lieu of doing the requirements of 
paragraph (g) of this AD, do the applicable actions specified in 
paragraphs (h)(1), (h)(2), and (h)(3) of this AD.
    (1) For MD-11 and MD-11F airplanes: Do the actions specified in 
paragraphs (h)(1)(i) and (h)(1)(ii) of this AD.
    (i) As of 48 months after April 15, 2016 (the effective date of 
AD 2016-04-16), change the fuel pump control and indication system 
wiring, in accordance with the Accomplishment Instructions of Boeing 
Service Bulletin MD11-28-137, dated June 24, 2014.
    (ii) Prior to or concurrently with accomplishing the actions 
specified in paragraph (h)(1)(i) of this AD: Replace the fuel pump 
control relays with fault current detectors, and change the fuel 
tank boost/transfer pump wire termination, in accordance with 
Accomplishment Instructions of Boeing Alert Service Bulletin MD11-
28A133, dated June 5, 2014.
    (2) For 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: Do the actions specified in paragraphs (h)(2)(i) and 
(h)(2)(ii) of this AD.
    (i) As of 48 months after April 15, 2016 (the effective date of 
AD 2016-04-16), change the fuel pump control and indication system 
wiring, in accordance with the Accomplishment Instructions of Boeing 
Service Bulletin DC10-28-256, dated June 24, 2014.
    (ii) Prior to or concurrently with accomplishing the actions

of this AD, as applicable; or within 30 days after the effective 
date of this AD; whichever occurs later.
    (2) If the optional revision specified in paragraph (l)(1) of 
this AD is accomplished: After the maintenance or inspection program 
has been revised as provided by paragraph (1)(1) of this AD, no 
alternative actions (e.g., inspections), intervals, or CDCCLs may be 
used unless the actions, intervals, or CDCCLs are approved as an 
AMOC in accordance with the procedures specified in paragraph (m) of 
this AD.

(m) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles ACO Branch, FAA, has the authority 
to approve AMOCs for this AD, if requested using the procedures 
found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your 
request to your principal inspector or local Flight Standards 
District Office, as appropriate. If sending information directly to 
the manager of the certification office, send it to the attention of 
the person identified in paragraph (n) of this AD. Information may 
be emailed to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by the Boeing Commercial Airplanes Organization 
Designation Authorization (ODA) that has been authorized by the 
Manager, Los Angeles ACO Branch, FAA, to make those findings. To be 
approved, the repair method, modification deviation, or alteration 
deviation must meet the certification basis of the airplane, and the 
approval must specifically refer to this AD.
    (4) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(m)(4)(i) and (m)(4)(ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
