ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for all The
Boeing Company Model 737–100, –200,
–200C, –300, –400, and –500 series
airplanes. This AD was prompted by
fuel system reviews conducted by the
manufacturer. This AD requires
installing an automatic shutoff system
for the center and auxiliary tank fuel

Jkt 238001
revising the airplane flight manual
(AFM) to advise the flight crew of
certain operating restrictions for
airplanes equipped with an automatic
shutoff system; and revising the
maintenance program by incorporating
new airworthiness limitations for fuel
tank systems to satisfy Special Federal
Aviation Regulation No. 88
requirements. We are issuing this AD to
prevent operation of the center and
auxiliary tank fuel boost pumps with
continuous low pressure, which could
lead to friction sparks or overheating in
the fuel pump inlet that could create a
potential ignition source inside the
center and auxiliary fuel tanks. These
conditions, in combination with
flammable fuel vapors, could result in a
fuel tank explosion and consequent loss
of the airplane.
DATES: This AD is effective October 31,
2016.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of October 31, 2016.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of
proposed rulemaking (SNPRM) to
amend 14 CFR part 39 by adding an AD
that would apply to all The Boeing
Company Model 737–100, –200, –200C,
–300, –400, and –500 series airplanes.
The SNPRM published in the Federal
Register on March 28, 2016 (81 FR
17098) (‘‘the SNPRM’’). We preceded
the SNPRM with a notice of proposed
rulemaking (NPRM) that published in
the Federal Register on October 12,
2011 (76 FR 63229) (‘‘the NPRM’’). The
NPRM proposed to require installing an
automatic shutoff system for the center
and auxiliary tank fuel boost pumps, as
applicable; installing a placard in the
airplane flight deck if necessary;
replacing the P5–2 fuel system module
assembly; installing the UCO protection
system for the fuel boost pumps;
revising the airplane flight manual to
advise the flight crew of certain
operating restrictions for airplanes
equipped with an automatic shutoff
system; and revising the maintenance
program by incorporating new
airworthiness limitations for fuel tank
systems to satisfy Special Federal
Aviation Regulation No. 88
requirements. The NPRM was prompted
by fuel system reviews conducted by the
manufacturer. The SNPRM proposed to
require updated or additional actions for
certain airplane configurations. We are
issuing this AD to prevent operation of
the center and auxiliary tank fuel boost
pumps with continuous low pressure,
which could lead to friction sparks or
overheating in the fuel pump inlet that
could create a potential ignition source
inside the center and auxiliary fuel
tanks. These conditions, in combination
with flammable fuel vapors, could result
in a fuel tank explosion and consequent
loss of the airplane.
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comments
E:\FR\FM\26SER1.SGM
26SER1
Federal Register / Vol. 81, No. 186 / Monday, September 26, 2016 / Rules and Regulations
received on the SNPRM and the FAA’s
response to each comment. Boeing
concurred with the SNPRM.
Grouping Clarification for Airplanes
With Removed Airstairs
Phillippe Akot Azougo, ASLF,
reported on a discussion with Boeing
regarding the applicable airplane group
for an airplane from which the airstair
has been removed. Boeing indicated that
if all of the support structure is not
removed, the airplane is considered in
the group with airstairs. Based on this
comment, there is no need to change
this final rule regarding this issue.
Effect of Winglets on Accomplishment
of the Proposed Actions
Aviation Partners Boeing stated that
the installation of winglets per
Supplemental Type Certificate (STC)
ST01219SE does not affect the
accomplishment of the manufacturer’s
service instructions.
We agree with the commenter that
STC ST01219SE does not affect the
accomplishment of the manufacturer’s
service instructions. Therefore, the
installation of STC ST01219SE does not
affect the ability to accomplish the
actions required by this AD. We have
not changed this AD in this regard.
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 SNPRM for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the SNPRM.
We also determined that these changes
will not increase the economic burden
on any operator or increase the scope of
this AD.

Federal Register / Vol. 81, No. 186 / Monday, September 26, 2016 / Rules and Regulations
Authority for This Rulemaking
§ 39.13
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
(e) Unsafe Condition
This AD was prompted by fuel system
reviews conducted by the manufacturer. We
are issuing this AD to prevent operation of
the center and auxiliary tank fuel boost
pumps with continuous low pressure, which
could lead to friction sparks or overheating
in the fuel pump inlet that could create a
potential ignition source inside the center
and auxiliary fuel tanks. These conditions, in
combination with flammable fuel vapors,
could result in a fuel tank explosion and
consequent loss of the airplane.
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.

NORMAL FUEL USAGE
Center tank fuel pumps must not be "ON" unless personnel
are available in the flight deck to monitor low pressure
lights.
For ground operation, center tank fuel pump switches must
not be positioned "ON" unless the center tank fuel quantity
exceeds 1,000 pounds (453 kilograms), except when
defueling or transferring fuel. Upon positioning the center
tank fuel pump switches "ON," verify momentary
illumination of each center tank fuel pump low pressure
light.
For ground and flight operations, the corresponding center
tank fuel pump switch must be positioned "OFF" when a
center tank fuel pump low pressure light illuminates [1].
Both center tank fuel pump switches must be positioned
"OFF" when the first center tank fuel pump low pressure
light illuminates ifthe center tank is empty.
[1] When established in a level flight attitude, both center
tank pump switches should be positioned "ON" again if the
center tank contains usable fuel.
DEFUELING AND FUEL TRANSFER
When transferring fuel or defueling center or main tanks,
the fuel pump low pressure lights must be monitored and
the fuel pumps positioned to "OFF" at the first indication of
the fuel pump low pressure [ 1].
Defueling the main tanks with passengers on board is
prohibited ifthe main tank fuel pumps are powered [2].
Defueling the center tank with passengers on board is
prohibited if the center tank fuel pumps are powered and the
auto-shutoff system is inhibited [2].
[1] Prior to transferring fuel or defueling, conduct a lamp
test of the respective fuel pump low pressure lights.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of
proposed rulemaking (SNPRM) to
amend 14 CFR part 39 by adding an AD
that would apply to certain The Boeing
Company Model 747–100, 747–100B,
747–100B SUD, 747–200B, 747–200C,
747–200F, 747–300, 747–400, 747–
400D, 747–400F, 747SR, and 747SP
series airplanes. The SNPRM published
in the Federal Register on March 8,
2016 (81 FR 12041) (‘‘the SNPRM’’). We
preceded the SNPRM with a notice of
proposed rulemaking (NPRM) that
published in the Federal Register on
May 1, 2015 (80 FR 24850) (‘‘the
NPRM’’). The NPRM proposed to
require replacing the wire bundles
inside the electrical conduit of the
forward and aft boost pumps of the
numbers 1 and 4 main fuel tanks with
new, improved wire bundles inserted
into conduit liners. The NPRM was
prompted by several reports of chafing
of the wire bundles inside the electrical
conduit of the forward and aft boost
pumps of the numbers 1 and 4 main fuel
tanks due to high vibration. These wire
bundles can chafe through the wire
sleeving into the insulation, exposing
the wire conductors. The SNPRM
proposed to require a revision to the
maintenance or inspection program, as
applicable, to include CDCCLs for the
fuel boost pump wiring. We are issuing
this AD to prevent chafing of the wire
bundles and subsequent arcing between
the wiring and the electrical conduit
creating an ignition source in the fuel
tanks, which could result in a fire and
consequent fuel tank explosion.
Comments
We gave the public the opportunity to
participate in developing this AD. We
have considered the comments received.
The Air Line Pilots Association
International, Boeing, and United
Airlines supported the SNPRM.
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 SNPRM for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the SNPRM.

installing a placard in the airplane flight deck if necessary;
replacing the P5-2 fuel system module assembly; installing the
``uncommanded ON'' (UCO) protection system for the fuel boost pumps;
revising the airplane flight manual (AFM) to advise the flight crew of
certain operating restrictions for airplanes equipped with an automatic
shutoff system; and revising the maintenance program by incorporating
new airworthiness limitations for fuel tank systems to satisfy Special
Federal Aviation Regulation No. 88 requirements. We are issuing this AD
to prevent operation of the center and auxiliary tank fuel boost pumps
with continuous low pressure, which could lead to friction sparks or
overheating in the fuel pump inlet that could create a potential

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (SNPRM) to
amend 14 CFR part 39 by adding an AD that would apply to all The Boeing
Company Model 737-100, -200, -200C, -300, -400, and -500 series
airplanes. The SNPRM published in the Federal Register on March 28,
2016 (81 FR 17098) (``the SNPRM''). We preceded the SNPRM with a notice
of proposed rulemaking (NPRM) that published in the Federal Register on
October 12, 2011 (76 FR 63229) (``the NPRM''). The NPRM proposed to
require installing an automatic shutoff system for the center and
auxiliary tank fuel boost pumps, as applicable; installing a placard in
the airplane flight deck if necessary; replacing the P5-2 fuel system
module assembly; installing the UCO protection system for the fuel
boost pumps; revising the airplane flight manual to advise the flight
crew of certain operating restrictions for airplanes equipped with an
automatic shutoff system; and revising the maintenance program by
incorporating new airworthiness limitations for fuel tank systems to
satisfy Special Federal Aviation Regulation No. 88 requirements. The
NPRM was prompted by fuel system reviews conducted by the manufacturer.
The SNPRM proposed to require updated or additional actions for certain
airplane configurations. We are issuing this AD to prevent operation of
the center and auxiliary tank fuel boost pumps with continuous low
pressure, which could lead to friction sparks or overheating in the
fuel pump inlet that could create a potential ignition source inside
the center and auxiliary fuel tanks. These conditions, in combination
with flammable fuel vapors, could result in a fuel tank explosion and
consequent loss of the airplane.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments
[[Page 65865]]
received on the SNPRM and the FAA's response to each comment. Boeing
concurred with the SNPRM.
Grouping Clarification for Airplanes With Removed Airstairs
Phillippe Akot Azougo, ASLF, reported on a discussion with Boeing
regarding the applicable airplane group for an airplane from which the
airstair has been removed. Boeing indicated that if all of the support
structure is not removed, the airplane is considered in the group with
airstairs. Based on this comment, there is no need to change this final
rule regarding this issue.
Effect of Winglets on Accomplishment of the Proposed Actions
Aviation Partners Boeing stated that the installation of winglets
per Supplemental Type Certificate (STC) ST01219SE does not affect the
accomplishment of the manufacturer's service instructions.
We agree with the commenter that STC ST01219SE does not affect the
accomplishment of the manufacturer's service instructions. Therefore,
the installation of STC ST01219SE does not affect the ability to
accomplish the actions required by this AD. We have not changed this AD
in this regard.
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
SNPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the SNPRM.
We also determined that these changes will not increase the economic
burden on any operator or increase the scope of 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.

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.
