Distribution - Center Fuel Tank Boost Pump Auto Shutoff and Master Caution Logic Change This Revision includes all pages of the service bulletin. COMPLIANCE INFORMATION RELATED TO THIS REVISION More work is necessary on airplanes changed as shown in the Original Issue of this service bulletin dated January 11, 2006, or changed as shown in Revision 1 of this service bulletin dated January 30, 2008, and did not incorporate the Emergency AD 2008-24-51 dated November 18, 2008. These airplanes need to perform the operational test given in Accomplishment Instructions, paragraph 3.B, Work Instructions, PART 3. No more work is necessary on airplanes changed as shown in the Original Issue of this service bulletin dated January 11, 2006 or changed as shown in Revision 1 of this service bulletin dated January 30, 2008 and did accomplish Emergency AD 2008-24-51 dated November 18, 2008. REASON FOR REVISION This revision is sent to tell Operators that Boeing received a report from one Operator that the Left Hand Fuel Boost Pump of the Center Wing Tank failed to shut off after being selected "OFF" by the flightcrew during flight on a 737-700 airplane. Subsequent to that report, the same failure was found on two additional airplanes. Boeing determined that the failure was caused by a wire that was installed at a wrong location. During the incorporation of the service bulletin these operators terminated wire W0040-6402-14 incorrectly, to a different terminal block, and not to terminal block TB5060F as given in the instructions provided in Figure 33 and Figure 34, or Figure 35 and Figure 36. Wire W0040-6402-14 must be installed on Terminal Block TB5060F, terminal position 5. This terminal provides 115V AC from Transfer Bus 1, Section 2. If wire is installed incorrectly on terminal TB5060E or any other terminal block, the Auto Shutoff System will not function correctly and the Left Hand Center Tank Boost Pump may continue to operate after being selected off. This could result in a dry running pump. Fuel pumps that run dry and overheat could result in an ignition source in a fuel tank. This misswiring was the reason Airworthiness Directive AD 2008-24-51 was released and mandated by FAA on November 18, 2008. This revision is sent to tell operators that the AMM 28-22-00 - Center Tank Boost Pump Auto Shutoff Functional Test has been changed to incorporate the requirements of the AD 2008-24-51. The new Center Tank Boost Pump Auto Shutoff Functional Test will detect if the wire W0040-6402-14 is incorrectly installed. ### Page 8 Original Issue: January 11, 2006 Revision 2: May 21, 2009 737-28A1206 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 8 of 286 BOEING SERVICE BULLETIN 737-28A1206 ALERT ALERT Also this revision is sent to tell operators that the Accomplishment Instructions, paragraph 3.B., Work Instructions has been changed to a new format and grouped in two parts, PART 1 and PART 2.

REVISION HISTORY Original Issue: January 11, 2006 Revision 1: January 30, 2008 Revision 2: May 21, 2009 ### Page 11 Original Issue: January 11, 2006 Revision 2: May 21, 2009 737-28A1206 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 11 of 286 ALERT ALERT Commercial Airplanes 737 ALERTALERT Service Bulletin Number: 737-28A1206 Summary Original Issue: January 11, 2006 Revision 2: May 21, 2009 ATA System: 2822 3152 SUBJECT: FUEL - Distribution - Center Fuel Tank Boost Pump Auto Shutoff and Master Caution Logic Change 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 gives the instructions and a kit of parts to install an automatic shut off system for the fuel boost pumps in the center fuel tank. Time delay relays are installed in the J4 and J20 junction boxes that will shut off the pumps if the pumps operate with continuous low pressure for 15 seconds. If no fuel is available, the pump will turn off in 15 seconds. The master caution circuit is changed to provide indication to the flight crew when either center fuel tank pump runs dry for more than 10 seconds. The flight crew stays in primary control, with the automatic shut off system as backup, to stop the pumps after a low pressure indication. This service bulletin is the result of the safety assessments conducted by Boeing under SFAR 88, "Fuel Tank System Fault Tolerance Evaluation Requirements". Boeing found that fuel pump operation with continuous low pressure could result in friction sparks or overheating in the fuel pump inlet. The high temperatures could create a possible source of ignition of flammable fuel vapors in the fuel tanks. Ignition of flammable fuel vapors could cause a fire or explosion which could put the airplane in an unsafe condition. Installation of the automatic shut off system adds fuel pump inlet protection against friction sparks and friction overheat damage in the fuel tanks. This change affects section 9 of the Maintenance Planning Data (MPD) Document. New Airworthiness Limitations (AWL) "28-AWL-19" will be added to Section 9 of the MPD to include an operational check of the center tank boost pump Auto Shutoff System. This change also affects Section 1 and Section 3 of the FAA Approved Airplane Flight Manual (AFM). Boeing Service Related Problem (SRP) 737NG-SRP-28-0091 is related to this service bulletin. ### Page 12 Original Issue: January 11, 2006 Revision 2: May 21, 2009 737-28A1206 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 12 of 286 BOEING SERVICE BULLETIN 737-28A1206 ALERT ALERT As a part of a service bulletin validation program, this change was completed on airplane YE003 after the release of the original issue of this Service Bulletin.

If any parts or components are found, refer to Paragraph 2.C. for the recommended use. B. Concurrent Requirements The service bulletin(s) listed below must be done before or at the same time as this service bulletin: YJ471 10 YJ472–YJ480 11 YJ501–YJ513 10 YJ514–YJ517 11 YJ531–YJ537 11 YJ591–YJ592 11 YJ631–YJ632 11 YJ671–YJ682 11 YJ801–YJ822 11 YJ861–YJ867 11 YJ871 11 YJ901 11 YJ911–YJ916 11 YJ931–YJ933 11 YK001–YK005 11 YK101–YK104 11 YK111–YK112 11 YK121–YK122 11 YK131 11 YK301–YK302 11 YK321–YK322 11 YM101 11 Company Service Bulletin Description Boeing 233A3202-28-03 Original Issue This component service bulletin adds a new indication logic to the P5-2 Fuel Control Module. The new logic will give a low pressure master caution annunciation for each of the center tank fuel boost pumps. Variable Group ### Page 42 Original Issue: January 11, 2006 Revision 2: May 21, 2009 737-28A1206 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 42 of 286 BOEING SERVICE BULLETIN 737-28A1206 ALERT ALERT C. Reason This service bulletin gives the instructions and a kit of parts to install an automatic shut off system for the fuel boost pumps in the center fuel tank. Time delay relays are installed in the J4 and J20 junction boxes that will shut off the pumps if the pumps operate with continuous low pressure for 15 seconds. If no fuel is available, the pump will turn off in 15 seconds. The master caution circuit is changed to provide indication to the flight crew when either center fuel tank pump runs dry for more than 10 seconds. The flight crew stays in primary control, with the automatic shut off system as backup, to stop the pumps after a low pressure indication. This service bulletin is the result of the safety assessments conducted by Boeing under SFAR 88, "Fuel Tank System Fault Tolerance Evaluation Requirements". Boeing found that fuel pump operation with continuous low pressure could result in friction sparks or overheating in the fuel pump inlet. The high temperatures could create a possible source of ignition of flammable fuel vapors in the fuel tanks. Ignition of flammable fuel vapors could cause a fire or explosion which could put the airplane in an unsafe condition. Installation of the automatic shut off system adds fuel pump inlet protection against friction sparks and friction overheat damage in the fuel tanks. This change affects section 9 of the Maintenance Planning Data (MPD) Document. New Airworthiness Limitations (AWL) "28-AWL-19" will be added to Section 9 of the MPD to include an operational check of the center tank boost pump Auto Shutoff System. This change also affects Section 1 and Section 3 of the FAA Approved Airplane Flight Manual (AFM). Boeing Service Related Problem (SRP) 737NG-SRP-28-0091 is related to this service bulletin. As a part of a service bulletin validation program, this change was completed on airplane YE003 after the release of the original issue of this Service Bulletin. The change completed on airplane YE003 is equivalent to the change give in Revision 1 of this service bulletin. Airplane YE003 has the configuration of a Group 13 airplane. Revision 1 is sent to clarify the Parts Necessary For Each Airplane, Parts Modified and Reidentified, Parts Removed and Not Replaced, Accomplishment Instructions, location of the P61-8 Fuel Test Panel Installation for new Groups 13 thru 18. This revision also makes changes to the J4 Junction Box Relay Installation, W0094 Wire Bundle Routing, and Wire Bundle W0094 Wiring Change for the new Group 18 airplane. The Service Bulletin has also been updated to reflect the latest Service Bulletin format standards. These sections were changed: 1. Summary: A validation paragraph is added and the concurrent requirements and man-power paragraphs are changed. 2. Planning Information: Changes are made to the effectivity to add new Group 13 thru 18 airplanes. A validation paragraph is added to the Reason paragraph. A publication reference is added for the Illustrated Parts Catalog and the Operations Manual reference is replaced by the new Flight Crew Operations Manual reference. Man-power tables are added for each group. Information Notice 737-28A1206 IN 01 and FAA Approval Letter 140S-07-343 are added to the Approval statement.

The data given in Information Notice 737-28A1206 IN 01 and IN 02 is included in this revision. Revision 2 was sent to include the following changes This revision is sent to tell Operators that Boeing received a report from one Operator of failure of the Left Hand Fuel Boost Pump of the Center Wing Tank that failed to shut off after being selected "OFF" by the flight crew during flight on a 737-700 airplane. Subsequent to that report, the same failure was found on two additional airplanes. Boeing determined that the failure was caused by a wire that was installed at a wrong location. During the incorporation of the service bulletin these operators terminated wire W0040-6402-14 incorrectly, to a different terminal block, and not to terminal block TB5060F as given in the instructions provided in Figure 33 and Figure 34, or Figure 35 and Figure 36. Wire W0040-6402-14 has to be installed on Terminal Block TB5060F, terminal position 5. This terminal provides 115V AC from Transfer Bus 1, Section 2. If wire is installed incorrectly on terminal TB5060E or any other terminal block, the Auto Shutoff System will not function correctly and the Left Hand Center Tank Boost Pump may continue to operate after being selected off. This could result in a dry running pump. Fuel pumps that run dry and overheat could result in an ignition source in a fuel tank. This misswiring was the reason Airworthiness Directive AD 2008-24-51 was released and mandated by FAA on November 18, 2008. This revision is sent to tell operators that the AMM 28-22-00 - Center Tank Boost Pump Auto Shutoff Functional Test has been changed to incorporate the requirements of the AD 2008-24-51. The new Center Tank Boost Pump Auto Shutoff Functional Test will detect if the wire W0040-6402-14 is incorrectly installed. Also this revision is sent to tell operators that the Accomplishment Instructions, paragraph 3.B., Work Instructions has been changed to a new format and grouped in two parts, PART 1 and PART 2. A new part, PART 3 has been added that provides work instructions for Operators that incorporated the Original Issue of this service bulletin dated January 11, 2006 or Revision 1 of this service bulletin dated January 30, 2008, and did not accomplish Emergency AD 2008-24-51 dated November 18, 2008.

Approval This service bulletin was examined by the Federal Aviation Administration (FAA). The changes specified in this service bulletin comply with the applicable Federal Aviation Regulations (14 CFR Part 25) and Joint Aviation Requirements (JAR-25) and are FAA/JAA approved. This service bulletin and FAA/JAA approval were based on the airplane in it's original Boeing delivery configuration or as modified by other FAA/JAA 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 has approved the action (i.e. inspection or modification) defined in this service bulletin as an alternative method of compliance to the requirements of paragraph (a) of AD 2001-08-24 and paragraph (b) of AD 2002-24-51 and provides terminating action for the operational restrictions contained therein. All provisions of AD 2001-08-24 and AD 2002-24-51 that are not specifically referenced in the above statement remain fully applicable and must be complied with. Compliance with the conditions of this AMOC approval requires concurrent incorporation of the associated revisions to Airplane Flight Manual Section 1 and 3, and incorporation of the related Airworthiness Limitations (AWL) in Section 9 of the MPD into the operator’s maintenance documentation. The information that follows was given by Information Notice 737-28A1206 IN 01, dated July 27, 2006. The FAA has informed Boeing that Paragraph 1.F., Approval, which states that "the Manager of the FAA Seattle Aircraft Certification Office has approved the action defined in this service bulletin as an alternative method of compliance to the requirements of paragraph (a) of AD 2001-08-24 and paragraph (b) of AD 2002-24-51" is not complete. The FAA approval includes a condition as part of the approval of the AMOC. This condition of approval was not listed in Paragraph 1.F of the original issue of this service bulletin and is not part of the existing Airworthiness Directive, AD 2002-24-51. The condition of approval specified by the FAA addresses mixed fleet operations and requires work to be done on unmodified airplanes in addition to the actions defined in the service bulletin, to achieve the Alternative Method Of Compliance to the requirements of paragraph (b) of AD 2002-24-51. Additional information and the FAA AMOC Approval Letter 140S-06-6 containing the AMOC approval was sent by Multi Operator Message (MOM) 1-210695451-1. Additional copies of the FAA letter are available on request. 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 (b) of AD 2002-24-51 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 2002-24-51 fuel usage restrictions required", or for airplanes that currently have a placard required by AD 2002-19-52, that placard can be used to fulfill the above requirement for mixed fleet operation. 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 alternative method of compliance should be submitted to the Seattle Aircraft Certification Office. ### Page 53 Original Issue: January 11, 2006 Revision 2: May 21, 2009 737-28A1206 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 53 of 286 BOEING SERVICE BULLETIN 737-28A1206 ALERT ALERT In addition, the Manager of the FAA Seattle Aircraft Certification Office approves the action (i.e. inspection or modification) defined in this service bulletin as an alternative method of compliance to the requirements of paragraphs (f)(1) through (f)(10) of AD 2008-24-51.
