Service Bulletin

Number: 747-28A2288 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.

BOEING SERVICE BULLETIN 747-28A2288

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.
