Revision Transmittal SheetNumber: 737-28A1216Original Issue: July 29, 2010
Revision 1: March 26, 2012
ATA System: 2822
SUBJECT: FUEL - Engine Fuel Feed System - Installation of the Auto Shutoff Protection for the
Center and Auxiliary Fuel Tank Boost Pumps
This revision includes all pages of the service bulletin.
COMPLIANCE INFORMATION RELATED TO THIS REVISION
Federal Aviation Administration (FAA) Notice of Proposed Rule Making NPRM 2010-NM-189-AD, is related to
this service bulletin.
More work is necessary on the airplane(s) changed in accordance with the original issue of this service bulletin.
Operators that incorporated the original issue of this SB have to change the labels and wire termination in the
J2802 relay box assembly in accordance with Figures 3, 4, 5, 6, 7, 8, 9, or 10 as applicable, and do a functional
test within the compliance time specified in paragraph 1. E. Also, operators have to inspect the imprinted text
on the ID tape of wire W368-031-20 installed in accordance with Figures 82 and 83 or Figures 82 and 84 within
the compliance time specified in paragraph 1. E. Some wires W368-031-20 delivered in the kits have been
identified incorrectly as "W036-031-20". If they are imprinted as "W036-031-20", then correct that text of the I.D.
tapes to "W0368-031-20" using a permanent marker.
REASON FOR REVISION
This revision is sent to tell the operators that for airplanes with Airstairs the J2802 Box provided in the original
release can not be installed in the main equipment compartment on the E2 and E3 support posts in accordance
with Figure 12 or Figure 13. When J2802 Box is installed in accordance with Figure 12 or 13, the forward face
of the box interferes with the Airstairs and the Airstairs support structure. Also there is no good access to the
Airstairs relays, and to the wires connected to the Airstairs relays. A new J2802 Box Assembly was designed
and added to this revision that can be installed on airplanes with Airstairs with no interference with Airstairs and
the Airstairs support structure. The airplanes with Airstairs were moved from the existing groups into new groups
based on the wires configuration and Auxiliary Tank installation. Figures 92 through 107 were added for airplanes
with Airstairs.
This revision is also sent to tell the Operators that the switches S03318 and S03321 installed on J2802 box
have two positions (for each switch) identified as "POS 1" and "POS 2". POS 1 of the test switch S03318 is for
Left Fuel Boost Pump of the Center Tank. POS 1 of the test switch S03321 is for Right Fuel Boost Pump of the
Center Tank. POS 2 of the test switches S03318 and S03321 are only used for airplanes with Auxiliary Tanks.
POS 2 of the test switch S03318 is for Aft Fuel Boost Pump of the Auxiliary Tank. POS 2 of the test switch
S03321 is for Fwd Fuel Boost Pump of the Auxiliary Tank. The wires terminated at switches S03318 and S03321
were incorrectly terminated in Figures 4, 5, 7, 8, 9, 10. The wire terminations at switches S03318 and S03321
are changed in order for the switches to function as indicated.

New steps are added to Figure 3 that instruct the operators to install markers on the J2802 Box that will identify
S03318 and S003321 as "TEST SWITCHES". Also instructions are added to install markers that will identify the
function of the switch S03318 POS 1 as "CTR-L", and the function of the switch S03321 POS 1 as "CTR-R".
New steps are added to Figure 6 that instruct the operators to install markers on the J2802 Box that will identify
S03318 and S003321 as "TEST SWITCHES". Also instructions are added to install markers that will identify the
functions of the switch S03318 as follows: POS 1 as "CTR-L",and POS 2 as "AUX-AFT". Also instructions are
added to install markers that will identify the functions of the switch S03321 as follows: POS 1 as "CTR-R", and
POS 2 as "AUX-FWD".
Also this revision moves airplanes with airstairs from existing groups in new groups, Group 21 through 31. All
airplanes in Groups 14, 17, and 18 have airstairs.
Some wires W368-031-20 delivered in the kits have been identified incorrectly. The wire I.D. Tapes Part Number
61-74478-10906 installed on both ends of the wire W368-031-20 may be imprinted incorrectly as "W036-031-20".
Instructions are added to Figure 83 and Figure 84 to check the imprinted text on the wire I.D Tapes before
installation and correct the text from "W036-031-20" to "W0368-031-20" if necessary.
These sections were changed:
1. Summary:
a. Background: Updated PART 1 and PART 3. Changed PART 2 for airplanes with Airstairs. Added PART
4, PART 5, and PART 6 for airplanes with Airstairs.

Revision 1: March 26, 2012
ATA System: 2822
SUBJECT: FUEL - Engine Fuel Feed System - Installation of the Auto Shutoff Protection for the
Center and Auxiliary Fuel Tank Boost Pumps
THIS BULLETIN IS SENT TO THE OPERATORS OF RECORD OF THE AIRPLANES SHOWN IN PARAGRAPH
1.A., EFFECTIVITY. IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS SERVICE BULLETIN TO
THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO
THE NEW OWNER.
CONCURRENT REQUIREMENTS
Refer to Paragraph 1.B., Concurrent Requirements.
BACKGROUND
This service bulletin is the result of the safety analysis done by Boeing under SFAR 88, "Fuel Tank System Fault
Tolerance Evaluation Requirements." Initial results from the fuel system safety analysis shows that fuel boost
pumps that run dry could cause an overheat condition external of the fuel pump explosion resistance area that
is open to the fuel pump inlet. An overheat condition in this area could possibly cause an unwanted ignition
source for the fuel vapors in the fuel tank and could cause a fire or explosion.
This service bulletin gives the instructions and a kit of parts to install an automatic (auto) shut-off system for the
fuel boost pumps. The fuel boost pumps are installed in the center fuel tank and if equipped, also in the auxiliary
fuel tank. Time delay relays are installed in the new J2802 box assembly that will shut off the fuel boost pumps
if the pumps operate with continuous low pressure for 15 seconds. The 15 second time delay relay prevents
extended dry operation of the fuel boost pumps and allows for sufficient time for fuel pump inlet reprime to
prevent nuisance automatic shutoff. The flight crew stays in primary control, with the auto shutoff system as a
backup, to stop the fuel boost pumps after a low pressure indication.
The change installs an automatic shut off system that gives fuel boost pump inlet protection in the fuel tank
against sparks possibly caused by friction overheat damage.
This change affects the Fuel Systems Airworthiness Limitations section of Boeing document
"737-100/200/200C/300/400/500 Airworthiness Limitations (AWLs) and Certification Maintenance Requirements
(CMRs), D6-38278-CMR." New AWL "28-AWL-20" will be added to include an operational check of the boost
pump automatic shutoff system for the center fuel tank. AWL "28-AWL-21" will be added to include an operational
check of the fuel boost pump automatic shutoff system for the auxiliary fuel tank, if installed by Boeing. This
change also affects Section 1 and Section 3 of the FAA Approved Airplane Flight Manual (AFM).

2. Spares Affected
None.
B. Concurrent Requirements
The service bulletin(s) listed below must be done before or at the same time as this service bulletin:
DescriptionService BulletinCompany
Gives instruction to install a new printed
circuit assembly in the P5-2 fuel system
module assembly to supply Low fuel pres-
sure master caution Annunciation.
BAE Systems SB 69-37335-28-04, Revision
2, dated Feb 10/2010
BAE
Gives instruction to replace the P5-2 fuel
system module assembly to supply Low fuel
pressure master caution Annunciation.
737-28A1210, Revision 1Boeing
C. Reason
This service bulletin is the result of the safety analysis done by Boeing under SFAR 88, "Fuel Tank
System Fault Tolerance Evaluation Requirements." Initial results from the fuel system safety analysis
shows that fuel boost pumps that run dry could cause an overheat condition external of the fuel pump
explosion resistance area that is open to the fuel pump inlet. An overheat condition in this area could
possibly cause an unwanted ignition source for the fuel vapors in the fuel tank and could cause a fire
or explosion.
This service bulletin gives the instructions and a kit of parts to install an automatic (auto) shut-off system
for the fuel boost pumps. The fuel boost pumps are installed in the center fuel tank and if equipped,
also in the auxiliary fuel tank. Time delay relays are installed in the new J2802 box assembly that will
shut off the fuel boost pumps if the pumps operate with continuous low pressure for 15 seconds. The
15 second time delay relay prevents extended dry operation of the fuel boost pumps and allows for
sufficient time for fuel pump inlet reprime to prevent nuisance automatic shutoffs. The flight crew stays
in primary control, with the auto shut off system as a backup, to stop the fuel boost pumps after a low
pressure indication.
The change installs an automatic shut off system that gives fuel boost pump inlet protection in the fuel
tank against sparks possibly caused by friction overheat damage.

This change affects the Fuel Systems Airworthiness Limitations section of Boeing document
"737-100/200/200C/300/400/500 Airworthiness Limitations (AWLs) and Certification Maintenance
Requirements (CMRs), D6-38278-CMR." New AWL "28-AWL-20" will be added to include an operational
check of the boost pump automatic shutoff system for the center fuel tank. AWL "28-AWL-21" will be
added to include an operational check of the fuel boost pump automatic shutoff system for the auxiliary
fuel tank, if installed by Boeing. This change also affects Section 1 and Section 3 of the FAA Approved
Airplane Flight Manual (AFM).
Other related airplane service bulletins are Service Bulletin 737-28A1228 for the 737-100/200 airplanes
and Service Bulletin 737-28A1206 for the 737-600/700/800/900 airplanes.
Revision 1:
This revision is sent to tell the operators that for airplanes with Airstairs the J2802 Box provided in the
original release can not be installed in the main equipment compartment on the E2 and E3 support
posts in accordance with Figure 12 or Figure 13. When J2802 Box is installed in accordance with Figure
12 or 13, the forward face of the box interferes with the Airstairs and the Airstairs support structure.
Also there is no good access to the Airstairs relays, and to the wires connected to the Airstairs relays.
A new J2802 Box Assembly was designed and added to this revision that can be installed on airplanes
with Airstairs with no interference with Airstairs and the Airstairs support structure. The airplanes with
Airstairs were moved from the existing groups into new groups based on the wires configuration and
Auxiliary Tank installation. Figures 92 through 107 were added for airplanes with Airstairs.
This revision is also sent to tell the Operators that the switches S03318 and S03321 installed on J2802
box have two positions (for each switch) identified as "POS 1" and "POS 2". POS 1 of the test switch
S03318 is for Left Fuel Boost Pump of the Center Tank. POS 1 of the test switch S03321 is for Right
Fuel Boost Pump of the Center Tank. POS 2 of the test switches S03318 and S03321 are only used
for airplanes with Auxiliary Tanks. POS 2 of the test switch S03318 is for Aft Fuel Boost Pump of the
Auxiliary Tank. POS 2 of the test switch S03321 is for Fwd Fuel Boost Pump of the Auxiliary Tank. The
wires terminated at switches S03318 and S03321 were incorrectly terminated in Figures 4, 5, 7, 8, 9,
10. The wire terminations at switches S03318 and S03321 are changed in order for the switches to
function as indicated.
New steps are added to Figure 3 that instruct the operators to install markers on the J2802 Box that
will identify S03318 and S003321 as "TEST SWITCHES". Also instructions are added to install markers
that will identify the function of the switch S03318 POS 1 as "CTR-L", and the function of the switch
S03321 POS 1 as "CTR-R".
New steps are added to Figure 6 that instruct the operators to install markers on the J2802 Box that
will identify S03318 and S003321 as "TEST SWITCHES". Also instructions are added to install markers
that will identify the functions of the switch S03318 as follows: POS 1 as "CTR-L",and POS 2 as
"AUX-AFT". Also instructions are added to install markers that will identify the functions of the switch
S03321 as follows: POS 1 as "CTR-R", and POS 2 as "AUX-FWD".
Also this revision moves airplanes with airstairs from existing groups in new groups, Group 21 through
31. All airplanes in Groups 14, 17, and 18 have airstairs.
Some wires W368-031-20 delivered in the kits have been identified incorrectly. The wire I.D. Tapes
Part Number 61-74478-10906 installed on both ends of the wire W368-031-20 may be imprinted
incorrectly as "W036-031-20". Instructions are added to Figure 83 and Figure 84 to check the imprinted
text on the wire I.D Tapes before installation and correct the text from "W036-031-20" to "W0368-031-20"
if necessary.

labels and wire termination in the J2802 relay box assembly in accordance with Figures 3, 4, 5, 6, 7,
8, 9, or 10 as applicable, and do a functional test within the compliance time specified in paragraph 1.
E. Also, operators have to inspect the imprinted text on the ID tape of wire W368-031-20 installed in
accordance with Figures 82 and 83 or Figures 82 and 84 within the compliance time specified in
paragraph 1. E. Some wires W368-031-20 delivered in the kits have been identified incorrectly as
"W036-031-20". If they are imprinted as "W036-031-20", then correct that text of the I.D. tapes to
"W0368-031-20" using a permanent marker
The work in this service bulletin is done in the maintenance zone(s) given below.

E. Compliance
Federal Aviation Administration (FAA) Notice of Proposed Rule Making NPRM 2010-NM-189-AD, is
related to this service bulletin.
The Federal Aviation Administration (FAA) will possibly release an Airworthiness Directive related to
this service bulletin. The Airworthiness Directive will make the compliance tasks and times given in this
service bulletin mandatory.
Boeing recommends that the change given in this service bulletin be done within 36 months after the
original issue date of this service bulletin.
F. Approval
This service bulletin was examined by the Federal Aviation Administration (FAA). The changes specified
in this service bulletin comply with the applicable regulations and are FAA approved, as well as European
Aviation Safety Agency (EASA)/Joint Aviation Authorities (JAA) approved for all EASA/JAA approved
airplanes listed in the service bulletin effectivity. This service bulletin and its approval were based on
the airplane in its original Boeing delivery configuration or as modified by other approved Boeing
changes.
If an airplane has a non-Boeing modification or repair that affects a component or system also affected
by this service bulletin, the operator is responsible for obtaining appropriate regulatory agency approval
before incorporating this service bulletin.
This service bulletin has been approved by the FAA. In addition, the Manager of the FAA Seattle Aircraft
Certification Office approves the installation of the automatic shutoff system for the center tank fuel
pumps in accordance with this service bulletin and the installation of a modified P5-2 Fuel System
Module in accordance with Service Bulletin 737-28A1210, Revision 1, as an alternative method of
compliance (AMOC) to the requirements of paragraph (a) of AD 2001-08-24. Compliance with the
conditions of this AMOC approval requires concurrent incorporation of the associated revisions to
Airplane Flight Manual Sections 1 and 3 and incorporation of Airworthiness Limitations (AWL)
28-AWL-20in Boeing document "737-100/200/200C/300/400/500 Airworthiness Limitations (AWLs)
and Certification Maintenance Requirements (CMRs), D6-38278-CMR," into the operator's maintenance
documentation. In order to operate a mixed fleet of airplanes, some having automatic shutoff installed
and others without automatic shutoff, it will be necessary to install a placard in the flight deck of airplanes
that do not have automatic shutoff installed to alert the crew that the procedures required by paragraph(a)
of AD 2001-08-24 must be followed on that airplane. The placard should read as follows (alternative
placard wording may be used if approved by an appropriate FAA Principal Operations Inspector):
'AD 2001-08-24 fuel usage restrictions required"
If an operator would like to use a different method of placarding their airplanes for operation as a mixed
fleet, a request for approval of an AMOC should be submitted to the Seattle Aircraft Certification Office.
All provisions of AD 2001-08-24 that are not specifically referenced in the above statement remain fully
applicable and must be complied with.
G. Manpower
The table below shows an estimate of the task-hours necessary to do this change for each airplane.
This estimate is for direct labor only, done by an experienced crew. Adjust the estimate with operator
task-hour data if necessary. The estimate does not include lost time. These are some examples of lost
time:
