### Commercial **Airplanes** 

# 777 Service Bulletin **Summary Number: 777-28A0039**  Original Issue: June 13, 2008 Revision 2: September 20, 2010 ATA System: 2822 2409 **SUBJECT:** FUEL - Engine Fuel Feed System - Electrical Load Management (ELM) System - Software Change **CONCURRENT REQUIREMENTS** Refer to Paragraph 1.B., Concurrent Requirements. **BACKGROUND** This service bulletin installs new Electrical Load Management System (ELMS) software. The software changes help prevent a possible ignition source in the center wing fuel tank caused by a fuel pump that may continue to operate after the fuel level goes below the pump inlet. An ignition source in a fuel tank could result in a fire or an explosion. A safety assessment conducted by Boeing under Special Federal Aviation Regulation (SFAR) 88 indicated that the center override/jettison pumps may continue to operate for an extended time after the fuel level goes below the pump inlet. When a pump runs after the fuel level goes below the pump inlet, there is a small risk that the pumps can cause an ignition source in the fuel tank from an overheat condition, electrical arcs or frictional sparks. The ELMS software has these changes to help make sure that the risk of an ignition source in the fuel tank is kept to a minimum: — The ELMS software sets or clears the "FUEL IN CENTER" and "FUEL LOW CENTER" advisory message bits based on new wet-shutoff logic. — The low fuel level indication is given by the "FUEL LOW CENTER" message on the Engine Indication and Crew Alerting System based on new wet-shutoff logic. The ELMS software automatically stops each center override/jettison fuel pump at 15 seconds after a low pressure indication from a pump pressure switch, if the pumps are not shut off manually by the flight crew before end of the 15 second period. — ELMS sets the "FUEL IN CENTER" advisory message bit based on new wet-shutoff logic. The AIMS receives the bit from ELMS. The "FUEL IN CENTER" message is then shown on EICAS to tell the flight crew that the pumps can be put ON. — ELMS sets the "FUEL PUMP CENTER L" or the "FUEL PUMP CENTER R" status messages when the left or right pump pressure switch indicates high pressure with the pump commanded OFF. — ELMS monitors and controls the new relays installed by Service Bulletin 777-28A0037 in the center override/jettison fuel pump circuit. ELMS removes power from a center override/jettison pump when the inputs to ELMS show that the pump continues to operate after the pump has been commanded OFF. **ACTION (PRR 61998-2)** Install new Operational Program Software (OPS) software in the ELMS electronics units in the P110, P210, and P310 power management panels.

**Description Service Bulletin**  **Company** Gives the procedures to install necessary software changes for the Airplane Information Management System (AIMS) to give status messages to Engine Indicating and Crew Alerting (EICAS). 777-31-0098 original issue thru Revision 1 Boeing

The service bulletin listed below must be done at the same time as this service bulletin: **Description Service Bulletin**  **Company** Gives procedures to install the electrical hardware and wiring necessary for the redundant control of jettison fuel pumps. 777-28A0037 original issue thru Revision 1 Boeing

**C. Reason** This service bulletin installs new Electrical Load Management System (ELMS) software. The software changes help prevent a possible ignition source in the center wing fuel tank caused by a fuel pump that may continue to operate after the fuel level goes below the pump inlet. An ignition source in a fuel tank could result in a fire or an explosion.

Original Issue: June 13, 2008 777-28A0039 Revision 2: September 20, 2010 17 of 58 **BOEING SERVICE BULLETIN 777-28A0039**A safety assessment conducted by Boeing under Special Federal Aviation Regulation (SFAR) 88 indicated that the center override/jettison pumps may continue to operate for an extended time after the fuel level goes below the pump inlet. When a pump runs after the fuel level goes below the pump inlet, there is a small risk that the pumps can cause an ignition source in the fuel tank from an overheat condition, electrical arcs or frictional sparks. The ELMS software has these changes to help make sure that the risk of an ignition source in the fuel tank is kept to a minimum: — The ELMS software sets or clears the "FUEL IN CENTER" and "FUEL LOW CENTER" advisory message bits based on new wet-shutoff logic. — The low fuel level indication is given by the "FUEL LOW CENTER" message on the Engine Indication and Crew Alerting System based on new wet-shutoff logic. The ELMS software automatically stops each center override/jettison fuel pump at 15 seconds after a low pressure indication from a pump pressure switch, if the pumps are not shut off manually by the flight crew before end of the 15 second period. — ELMS sets the "FUEL IN CENTER" advisory message bit based on new wet-shutoff logic. The AIMS receives the bit from ELMS. The "FUEL IN CENTER" message is then shown on EICAS to tell the flight crew that the pumps can be put ON. — ELMS sets the "FUEL PUMP CENTER L" or the "FUEL PUMP CENTER R" status messages when the left or right pump pressure switch indicates high pressure with the pump commanded OFF. — ELMS monitors and controls the new relays installed by Service Bulletin 777-28A0037 in the center override/jettison fuel pump circuit. ELMS removes power from a center override/jettison pump when the inputs to ELMS show that the pump continues to operate after the pump has been commanded OFF. Revision 1 was sent to correct discrepancies in the service bulletin. Revision 2 is sent to add a new airplane configuration to this service bulletin effectivity. Electrical Load Management System (ELMS) Operational Program Configuration (OPC) software 2415-SMI-A03-53 is necessary for Group 54 airplanes WC051-WC067 if Boeing Service Bulletin 777-23-0183 is incorporated. Terminology has been changed in the Work Instructions to agree with the terminology defined in Paragraph 3.A., General Information - Notes. The data given in Information Notice 777-28A0039 IN02 and 777-28A0039 IN03 are included in this revision. **D. Description** Install new Operational Program Software (OPS) software in the ELMS electronics units in the P110, P210, and P310 power management panels. **Group 20:** Boeing Service Bulletin 777-23-0046 is related to this service bulletin. **Group 39:** Boeing Service Bulletin 777-31-0123 is related to this service bulletin. **Group 41:** Boeing Service Bulletin 777-25-0413 is related to this service bulletin.
