This Revision includes all pages of the service bulletin.

COMPLIANCE INFORMATION RELATED TO THIS REVISION No more work is necessary on airplanes that have accomplished the intent of Boeing 777-23-0141 Service Bulletin.

REASON FOR REVISION This revision is sent to make Boeing 777-23-0141 Service Bulletin a prior requirement for Boeing 777-23-0176 Service Bulletin. Accomplishing 777-23-0141 Service Bulletin ensures Cabin Management System (CMS) hardware and software compatibility. These sections were changed: 1. In Summary/Concurrent Requirements, added Boeing Service Bulletin 777-23-0141. 2. In Planning Information, Paragraph 1.B., added Boeing service Bulletin 777-23-0141. 3. In Planning Information, Paragraph 1.C., added a list of the sections of the service bulletin that were changed. 4. In Planning Information, Paragraph 1.D., added Revision 2 information. 5.

### Summary Date: January 09, 2003 Revision 2: October 26, 2006 ATA System: 2339 SUBJECT: COMMUNICATIONS - Cabin Management System (CMS) - Change the Operational Software

CONCURRENT REQUIREMENTS Boeing service bulletin 777-23-0010, is necessary to be accomplished prior to or concurrent with this service bulletin on the same airplanes. Boeing service bulletin 777-23-0141, is necessary to be accomplished prior to this service bulletin.

BACKGROUND Boeing Service Related Problem (SRP) 777-SRP-24-0091 is related to this service bulletin. The change described in this service bulletin will change the operation of cabin lighting system when the CABIN/ UTILITY switch is installed. We have received numerous reports of smoke or flames in the passenger cabin related to the wiring for the passenger cabin in-flight entertainment system, cabin lighting and passenger seats. It is not easy to remove the electrical power to these systems to stop the smoke and flames. A CABIN/UTILITY switch can be installed to remove power to some systems in the passenger cabin. This change to the cabin management system (CMS) operational software (OPS) will change the way various lighting systems operate when the switch is set to "OFF". When the CABIN/UTILITY switch is set to OFF, all night lights, reading lights and attendant work lights will come on. Commands from the attendant switch panel for night light operation will be ignored. A message will be shown on the cabin control panels which says "REDUCED POWER CONDITION - Fluorescent lights may be off. Night lights are locked on". This message replaces the Function Lock-Out - Reduced Power pop-up screen. When the CABIN/UTILITY switch is set to ON, control of the cabin lighting systems by the cabin control panels is put back to normal and the REDUCED POWER CONDITION message is removed. The cabin control panels will show the state of the CABIN/UTILITY switch on the Input Monitor - ARINC 629 Bus screen.January 09, 2003 Revision 2: October 26, 2006 777-23-0176 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 8 of 23

ACTION Install a new OPS in the Cabin Area Control Panel (CACP), Zone Management Units (ZMU), Cabin System Management Unit (CSMU) and the Cabin System Control Panel (CSCP). Make a change to the CMS configuration database (CDB). Install the new database in the CMS components.

EFFECTIVITY All 777 airplanes variable numbers WA002-WA017, WA076-WA080, WA086-WA093, WA116-WA119, WA131- WA137, WA171-WA175, WA196-WA198, WA206-WA209, WA261-WA266, WB001-WB015, WB051-WB082, WB101-WB104, WB121-WB125, WB131-WB132.

COMPLIANCE No compliance time is given.

Boeing service bulletin 777-23-0141, is necessary to be accomplished prior to this service bulletin.

C. Reason Boeing Service Related Problem (SRP) 777-SRP-24-0091 is related to this service bulletin. The change described in this service bulletin will change the operation of cabin lighting system when the CABIN/UTILITY switch is installed. We have received numerous reports of smoke or flames in the passenger cabin related to the wiring for the passenger cabin in-flight entertainment system, cabin lighting and passenger seats. It is not easy to remove the electrical power to these systems to stop the smoke and flames. A CABIN/UTILITY switch can be installed to remove power to some systems in the passenger cabin. This change to the cabin management system (CMS) operational software (OPS) will change the way various lighting systems operate when the switch is set to "OFF". When the CABIN/UTILITY switch is set to OFF, all night lights, reading lights and attendant work lights will come on. Commands from the attendant switch panel for night light operation will be ignored. A message will be shown on the cabin control panels which says "REDUCED POWER CONDITION -Fluorescent lights may be off. Night lights are locked on". This message replaces the Function LockOut - Reduced Power pop-up screen. When the CABIN/UTILITY switch is set to ON, control of the cabin lighting systems by the cabin control panels is put back to normal and the REDUCED POWER CONDITION message is removed. The cabin control panels will show the state of the CABIN/UTILITY switch on the Input Monitor - ARINC 629 Bus screen. Revision 1 is issued to correct the reference to the Boeing Configuration Database Generator (CDG) User Manual from D634W602-1 to D634W601-1, Version 285W0304-6 or later. The detailed instructions for changes to the cabin attendant work lights functions have also been changed. Part (2) is added for airplanes with the ground service bus loss special function (in the CDB) but no crew rest area. The necessary CDG software disk set 285W0304-6, with software 285W0347-06, is added to the Material Information data. Revision 2 is sent to make Boeing 777-23-0141 Service Bulletin a prior requirement for Boeing 777- 23-0176 Service Bulletin. Accomplishing 777-23-0141 Service Bulletin ensures Cabin Management System (CMS) hardware and software compatibility. These sections were changed: 1. In Summary/Concurrent Requirements, added Boeing Service Bulletin 777-23-0141. 2. In Planning Information, Paragraph 1.B., added Boeing service Bulletin 777-23-0141. 3. In Planning Information, Paragraph 1.C., added Revision 2 information. 4. In Planning Information, Paragraph 1.D., added Revision 2 information. 5. In Planning Information, Paragraph 1.J.1., added Boeing Service Bulletin 777-23-0141.January 09, 2003 Revision 2: October 26, 2006 777-23-0176 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 12 of 23

6. In Accomplishment Instructions, Paragraph 3.B.10.d., added steps to complete Configuration Database (CDB) changes and get the Buyer Furnished Equipment (BFE) files. D. Description A new OPS is installed in the Cabin Area Control Panel (CACP), the Zone Management Units (ZMU), the Cabin System Management Unit (CSMU) and the Cabin System Control Panel (CSCP). A change to the CMS configuration database (CDB) is made. The new database is installed in the CMS components. Revision 1 - No more work is necessary on airplanes changed as shown in the initial release of this service bulletin. It is assumed that the changes were made correctly even though the wrong User Manual was referenced. Revision 2 - No more work is necessary on airplanes that have accomplished the intent of Boeing 777- 23-0141 Service Bulletin. E. Compliance No compliance time is given. 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.
