We are superseding Airworthiness Directive (AD) 2012-18-05 for The Boeing Company Model DC-9-10, DC-9-20, DC-9-30, DC-9-40, and DC-9- 50 series airplanes; and Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9- 83 (MD-83), DC-9-87 (MD-87), MD-88, and MD-90-30 airplanes; equipped with a center wing fuel tank and Boeing original equipment manufacturer-installed auxiliary fuel tanks. AD 2012-18-05 required adding design features to detect electrical faults and to detect a pump running in an empty fuel tank. Since we issued AD 2012-18-05, we have determined that it is necessary to clarify the actions for airplanes on which the auxiliary fuel tanks are removed. This new AD allows certain actions as optional methods of compliance. This AD was prompted by our determination that it is necessary to clarify the actions for airplanes on which the auxiliary fuel tanks are removed. 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.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2012-18-05 for 
The Boeing Company Model DC-9-10, DC-9-20, DC-9-30, DC-9-40, and DC-9-
50 series airplanes; and Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-
83 (MD-83), DC-9-87 (MD-87), MD-88, and MD-90-30 airplanes; equipped 
with a center wing fuel tank and Boeing original equipment 
manufacturer-installed auxiliary fuel tanks. AD 2012-18-05 required 
adding design features to detect electrical faults and to detect a pump 
running in an empty fuel tank. Since we issued AD 2012-18-05, we have 
determined that it is necessary to clarify the actions for airplanes on 
which the auxiliary fuel tanks are removed. This new AD allows certain 
actions as optional methods of compliance. This AD was prompted by our 
determination that it is necessary to clarify the actions for airplanes 
on which the auxiliary fuel tanks are removed. 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.

DATES: This AD is effective March 23, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 23, 
2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR

[[Page 7968]]

part 39 to supersede AD 2012-18-05, Amendment 39-17181 (77 FR 54793, 
September 6, 2012). AD 2012-18-05 applied to The Boeing Company Model 
DC-9-10, DC-9-20, DC-9-30, DC-9-40, and DC-9-50 series airplanes; and 
Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-
87), MD-88, and MD-90-30 airplanes; equipped with a center wing fuel 
tank and Boeing original equipment manufacturer-installed auxiliary 
fuel tanks. The NPRM published in the Federal Register on March 26, 
2015 (80 FR 15947). The NPRM was prompted by our determination that it 
is necessary to clarify the actions for airplanes on which the 
auxiliary fuel tanks are removed. The NPRM proposed to allow certain 
actions as optional methods of compliance. We are issuing this AD to 
correct the unsafe condition on these products.

Explanation of Revised Service Information

    The NPRM (80 FR 15947, March 26, 2015) specified Boeing Service 
Bulletin MD80-28-228, dated September 27, 2013; and Boeing Service 
Bulletin MD90-28-013, dated September 27, 2013; as the appropriate 
sources of service information for the required actions. Since the NPRM 
was published, both service bulletins have been revised and this AD now 
specifies Boeing Service Bulletin MD80-28-228, Revision 1, dated August 
27, 2015; and Boeing Service Bulletin MD90-28-013, Revision 1, dated 
August 27, 2015, as the source of appropriate service information for 
the required actions. Boeing Service Bulletin MD80-28-228, Revision 1, 
dated August 27, 2015; and Boeing Service Bulletin MD90-28-013, 
Revision 1, dated August 27, 2015; both clarify the required actions 
and require enlarging holes and identifying a bracket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (80 
FR 15947, March 26, 2015) and the FAA's response to each comment.

Support for the Comment

    Delta Air Lines supported the comments made by Boeing, which are 
discussed in the following paragraphs.

Request To Revise the Applicability

    Boeing requested that we revise paragraph (c) of the proposed AD 
(80 FR 15947, March 26, 2015). Boeing explained that the proposed AD 
should apply to the airplanes identified in paragraphs (c)(6) through 
(c)(8) of the proposed AD if they are equipped with center wing fuel 
tanks, and to airplanes identified in paragraphs (c)(1) through (c)(8) 
of the proposed AD if they are equipped with original equipment 
manufacturer-installed auxiliary fuel tanks. Boeing reasoned that DC-9 
center wing fuel tanks are not affected by the proposed AD, and that 
the ``fuel system reviews conducted by the manufacturer'' (i.e., 
Boeing's SFAR 88 system safety assessments (SSA)) cited in paragraph 
(e) of the proposed AD concluded that center wing fuel tanks on Model 
DC-9 airplanes identified as paragraphs (c)(1) through (c)(5) of the 
proposed AD do not require the corrective actions cited in the NPRM. 
For airplanes with a CWT identified in paragraphs (c)(1) through (c)(5) 
of the proposed AD, the existing design features offer adequate 
protection relative to a pump running in an empty fuel tank and new 
design features added to the center tank fuel boost pump container 
address types of electrical faults cited in the NPRM.
    Boeing expressed that the FAA had previously concurred with the 
related Boeing SSA findings and approved Boeing Service Bulletin DC9-
28-216, dated March 18, 2008, mandated by FAA AD 2009-03-03, Amendment 
39-15804 (74 FR 8150, February 24, 2009), as corrective action for the 
electrical arc burn-through.
    We agree to revise the applicability of this AD for the reasons 
stated by the commenter. We have revised paragraph (c) of this AD 
accordingly.

Request To Clarify Certain Optional Requirements

    Boeing requested that we revise paragraph (h)(1)(i) of the proposed 
AD (80 FR 15947, March 26, 2015) by adding the phrase, ``and change 
fuel pump system wiring'' after ``install ground fault interrupter 
(GFI) relays.'' Boeing reasoned that in addition to providing 
procedures for installing GFI relays, Boeing Service Bulletin MD80-28-
228, dated September 27, 2013, also incorporates wiring changes to 
accommodate the GFI's operation and revises low pressure indication 
system wiring for center wing and auxiliary fuel tank fuel pumps. The 
low pressure indication system wiring changes are required to address 
the potential of fuel pumps running for prolonged periods in empty 
tanks.
    Boeing also requested that we revise paragraph (h)(2) of the 
proposed AD (80 FR 15947, March 26, 2015) by removing the phrase, 
``install brackets and mod block rails, and'' and adding the phrase, 
``and change fuel pump system wiring.'' Boeing reasoned that while 
Boeing Service Bulletin MD90-28-013, dated September 27, 2013, does 
specify installation of brackets and rails, as does Boeing Service 
Bulletin MD80-28-228, dated September 27, 2013, the primary changes 
that will address the unsafe condition are the GFI relay and wiring 
changes defined in Boeing Service Bulletin MD90-28-013, dated September 
27, 2013. Boeing expressed that the brackets and rails can be omitted 
from the text of the NPRM, as they are referenced in the service 
information. Also, in addition to providing procedures for installing 
GFI relays, Boeing Service Bulletin MD90-28-013, dated September 27, 
2013, also incorporates wiring changes to accommodate the GFI's 
operation and revises low pressure indication system wiring for center 
wing and auxiliary fuel tank fuel pumps. Boeing stated that the low 
pressure indication system wiring changes are required to address the 
potential of fuel pumps running for prolonged periods in empty tanks.
    For the reasons stated by the commenter, we agree to revise 
paragraphs (h)(1)(i) and (h)(2) of this AD by incorporating the 
requested changes. As stated earlier, since the NPRM was published, 
both service bulletins have been revised and this AD now specifies 
Boeing Service Bulletin MD80-28-228, Revision 1, dated August 27, 2015; 
and Boeing Service Bulletin MD90-28-013, Revision 1, dated August 27, 
2015, as the appropriate sources of service information for the 
required actions.

Request To Revise to the Latest Service Information

    Delta requested that we revise paragraph (h)(3) of the proposed AD 
(80 FR 15947, March 26, 2015) to include the latest service 
information. Delta noted that the proposed AD would require the 
incorporation of ``Critical Design Configuration Control Limitations 
(CDCCLs), Airworthiness Limitations Instructions (ALIs), and short-term 
extensions specified in Appendixes B, C, and D of Boeing Special 
Compliance Item Report MDC-92K9145, Revision M'' into the maintenance 
and inspection program. Delta noted, however, that the referenced 
report has been revised to Revision N, dated June 13, 2014, and it 
recommends that the restriction to Revision M be removed from the final 
rule.
    For the reasons stated by the commenter, we have revised this AD to 
refer to the latest service information.

[[Page 7969]]

Request for Credit for Previously Accomplished Installations

    Delta requested that we revise paragraph (k) of the proposed AD (80 
FR 15947, March 26, 2015) to permit credit for previously accomplished 
installations for paragraph (h)(1)(i) or (h)(2) of the proposed AD. 
Delta reasoned that paragraph (h)(1)(i) of the proposed AD provides for 
the installation of GFI relays on Model MD-80 series airplanes (Model 
DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and 
Model MD-88 airplanes) using the procedures in Boeing Service Bulletin 
MD80-28-228, dated September 27, 2013. And similarly, paragraph (h)(2) 
of the proposed AD provides for the installation of GFI relays on MD-
90-30 airplanes in accordance with Boeing Service Bulletin MD9028-013, 
dated September 27, 2013. Delta explained that it has completed 
installation of GFI relays using the procedures in these two service 
bulletins on a portion of its fleet, and noted that there is no 
practical way to re-accomplish such modifications after the effective 
date of the final rule.
    For the reasons given by the commenter, and the addition of the 
latest service information, we have provided credit for the applicable 
actions specified in paragraph (k) of this AD.

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. We have determined that 
these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 15947, March 26, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 15947, March 26, 2015).
    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 Boeing Service Bulletin MD80-28-228, Revision 1, dated 
August 27, 2015; and Boeing Service Bulletin MD90-28-013, Revision 1, 
dated August 27, 2015. The service information describes procedures for 
installing GFI relays that change fuel pump system wiring, installing a 
low fuel pressure indication system, and enlarging holes and 
identifying a bracket.
    We have also reviewed Boeing Twinjet Special Compliance Item Report 
MDC-92K9145, Revision N, dated June 13, 2014, including Appendices A 
through D. This service information details special compliance items 
(SCIs), critical design configuration control limitations (CDCCLs), 
airworthiness limitation instructions (ALIs), short-term extensions, 
and associated compliance intervals.
    Boeing Service Bulletin MD80-28-228, Revision 1, dated August 27, 
2015, specifies prior or concurrent accomplishment of the following 
service information.
     McDonnell Douglas MD-80 Service Bulletin 28-53, Revision 
1, dated April 16, 1992, which describes procedures for installing a 
low fuel pressure indication system.
     McDonnell Douglas MD-80 Service Bulletin 28-63, Revision 
2, dated April 8, 1992, which describes procedures for installing a low 
fuel pressure indication inhibit system.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

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.

[[Page 7970]]

    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.

2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2012-18-05, Amendment 39-17181 (77 FR 54793, September 6, 2012, and 
adding the following new AD:

2016-03-06 The Boeing Company: Amendment 39-18393; Docket No. FAA-
2015-0249; Directorate Identifier 2014-NM-174-AD.

(a) Effective Date

    This AD is effective March 23, 2016.

(b) Affected ADs

    This AD replaces AD 2012-18-05, Amendment 39-17181 (77 FR 54793, 
September 6, 2012).

(c) Applicability

    This AD applies to The Boeing Company airplanes, certificated in 
any category, that are identified in paragraphs (c)(6) through 
(c)(8) of this AD and equipped with center wing fuel tanks; and 
those identified in paragraphs (c)(1) through (c)(8) of this AD that 
are equipped with Boeing original equipment manufacturer-installed 
auxiliary fuel tanks. For airplanes on which the auxiliary fuel 
tanks are removed, the actions specified for the auxiliary fuel 
tanks are not required.

DC-9-87 (MD-87) airplanes.
    (7) Model MD-88 airplanes.
    (8) Model MD-90-30 airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 28, Fuel.

(e) Unsafe Condition

    This AD was prompted by fuel system reviews conducted by the 
manufacturer. 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.

(f) Compliance

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

(g) Retained Criteria for Operation, With New Compliance Time

    This paragraph restates the actions required by paragraph (g) of 
AD 2012-18-05, Amendment 39-17181 (77 FR 54793, September 6, 2012), 
with a new compliance time. Except as provided by paragraphs (h) and 
(i) of this AD: As of 42 months after the effective date of this AD, 
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) and (g)(2) of this AD has been approved by the 
Manager, Los Angeles Aircraft Certification Office (ACO), FAA, and 
those design features are installed on the airplane.
    (1) Each electrically powered fuel pump installed in the center 
wing tank or auxiliary fuel tank must have a protective device 
installed to detect electrical faults that can cause arcing and burn 
through the fuel pump housing. 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 as the result 
of detection of an electrical fault, the device must stay latched 
off until the fault is cleared through maintenance action and 
verified that the pump and the electrical power feed are safe for 
operation.
    (2) Additional design features must be installed to detect when 
any center wing tank or auxiliary fuel tank pump is running in an 
empty fuel tank. The prospective pump shutoff system must shut off 
each pump no later than 60 seconds after the fuel tank is emptied. 
The pump shutoff system design must preclude undetected running of a 
fuel pump in an empty tank, after the pump was commanded off 
manually or automatically.

(h) New Optional Methods of Compliance

    For Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-
9-87 (MD-87), and Model MD-88 airplanes; and Model MD-90-30 
airplanes: 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 Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), 
DC-9-87 (MD-87), and Model MD-88 airplanes: Do the applicable 
actions specified in paragraphs (h)(1)(i), (h)(1)(ii), and 
(h)(1)(iii) of this AD.
    (i) For all airplanes identified in paragraph (h)(1) of this AD: 
Within the compliance time specified in paragraph (g) of this AD,
