CONCURRENT REQUIREMENTS Boeing service bulletin 777-24-0070, is necessary to be accomplished prior to or concurrent with 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 provide new switches on the flight deck that can remove power from the cabin systems if smoke or flames occur. Smoke and flames in the passenger cabin can cause injury to the passenger and damage the safety critical cabin equipments. 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 or flames. Two switches can be installed to remove power from some of the passenger cabin electrical systems. When selected OFF, the IFE/PASS SEATS switch will remove power from the systems connected to the following circuit breakers (if installed):
