### Summary Original Issue: March 22, 2008 Revision 1: January 21, 2010 ATA System: 2842 **SUBJECT:** FUEL - Fuel Pressure Indicating Systems - Installation of Indicator Lights in the P10 Panel and Replacement of Switches in the M154 Fuel Control Module in the P4 panel
**CONCURRENT REQUIREMENTS** Refer to Paragraph 1.B., Concurrent Requirements. **BACKGROUND** This service bulletin adds two new indicator lights in the flight deck to inform the captain and the first officer of a low fuel pressure condition of the left and right override/jettison pumps in the center wing tank and also modify the switches on P4 panel to turn these two new lights and the pumps off. This service bulletin is the result of the safety assessments conducted by Boeing Special Federal Aviation Regulation (SFAR) 88. The safety assessments show that center tank override jettison pumps that are uncommanded on could possibly cause an unwanted ignition source for the fuel vapors in the fuel tank. Ignition of flammable fuel vapors could cause a fire or explosion in an airplane. Currently there are lights on the P4 panel to provide pressure indicating for the left and right center wing override/jettison pump. These lights illuminate when the flight engineer turns off the pump before the fuel quantity falls to a preset level. They are illuminated to inform the flight engineer a low pressure or no fuel flow condition. The pump uncommanded-on is an event that indicates a potential of the pump running dry that requires the flight engineer to manually pull the pump circuit breaker to shut the pump off by cutting the power supply to them. To limit the potential of the pump running dry for an extended period of time, two indicator lights are added to the P10 panel to inform the captain and/or first officer a low fuel pressure condition. This service bulletin provides instructions to add two indicator lights on the P10 panel to inform the captain and the first officer the low pressure condition of the left and right override/jettison pumps in the center wing tank. This service bulletin also gives instructions to modify the left and right override/jettison (L or R OVRD/JETT) switches on the M154 fuel control module on the P4 to shut the pumps and the two new indicator lights off. This service bulletin provides instructions to replace the switches and do wiring changes to the M154 fuel control module on the P4 panel, add the left and right low pressure (L or R LOW PRESS) indicator lights on the P10 panel, and do the airplane wiring changes. This change affects the Airworthiness Limitations (AWL) data 28-AWL-22 in the Airworthiness Limitations and Certification Maintenance Requirements document to verify the functionality of the indicator lights on the P10 panel.Original Issue: March 22, 2008 Revision 1: January 21, 2010 747-28A2288 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 10 of 267

**C. Reason** This service bulletin adds two new indicator lights in the flight deck to inform the captain and the first officer of a low fuel pressure condition of the left and right override/jettison pumps in the center wing tank and also modify the switches on P4 panel to turn these two new lights and the pumps off. This service bulletin is the result of the safety assessments conducted by Boeing Special Federal Aviation Regulation (SFAR) 88. The safety assessments show that center tank override jettison pumps that are uncommanded on could possibly cause an unwanted ignition source for the fuel vapors in the fuel tank. Ignition of flammable fuel vapors could cause a fire or explosion in an airplane. Currently there are lights on the P4 panel to provide pressure indicating for the left and right center wing override/jettison pump. These lights illuminate when the flight engineer turns off the pump before the fuel quantity falls to a preset level. They are illuminated to inform the flight engineer a low pressure or no fuel flow condition. The pump uncommanded-on is an event that indicates a potential of the pump running dry that requires the flight engineer to manually pull the pump circuit breaker to shut the pump off by cutting the power supply to them. To limit the potential of the pump running dry for an extended period of time, two indicator lights are added to the P10 panel to inform the captain and/or first officer a low fuel pressure condition. This service bulletin provides instructions to add two indicator lights on the P10 panel to inform the captain and the first officer the low pressure condition of the left and right override/jettison pumps in the center wing tank. This service bulletin also gives instructions to modify the left and right override/ jettison (L or R OVRD/JETT) switches on the M154 fuel control module on the P4 to shut the pumps and the two new indicator lights off. This service bulletin provides instructions to replace the switches and do wiring changes to the M154 fuel control module on the P4 panel, add the left and right low pressure (L or R LOW PRESS) indicator lights on the P10 panel, and do the airplane wiring changes. This change affects the Airworthiness Limitations (AWL) data 28-AWL-22 in the Airworthiness Limitations and Certification Maintenance Requirements document to verify the functionality of the indicator lights on the P10 panel. Revision 1 is sent to provide the installation instruction of the LOW PRESS indicator lights for the airplanes that do not have the Warning Light panel. Wire W186-501-20 is added to wirekit 61B20560- 101W. The data given in Information Notice 747-28A2288 IN01 is included in this revision. Paragraph 1.A., Effectivity, shows changes of airplane groups. Each operator should examine the Effectivity paragraph for changes. **D. Description** Install the M154 fuel control module. Install the L and R LOW PRESS indicator lights on the P10 panel. Do the airplane wiring installation from P4 to P10. Do the functional test of the center wing pump Indicating light test. Revision 1 - No more work is necessary on airplanes changed as shown in the original issue of this service bulletin.Original Issue: March 22, 2008 Revision 1: January 21, 2010 747-28A2288 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 33 of 267

**E. Compliance** Federal Aviation Administration (FAA) Notice of Proposed Rule Making 2008-NM-108-AD, is related to this service bulletin. Boeing recommends the operators incorporate this service bulletin 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. **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: — Time to adjust to the workplace — Time to schedule the work — Time to examine the work — Time to cure the materials — Time to make the parts — Time to find the tools. 1.
