Spares Affected Examine your spares supply for the parts or components identified in Paragraph 2.C., Parts Necessary for Each Airplane. If any parts or components are found, refer to Paragraph 2.C. for the recommended use. **B. Concurrent Requirements** None. **C. Reason** Boeing received a report from an operator of arcing and smoke at the left number 2 window in the flight compartment. An investigation showed the cause of this problem to be mechanical damage at the connector backshell of the coil cord assembly. The new assembly will prevent mechanical damage which could cause a fire in the flight compartment. This service bulletin gives instructions to install a new coil cord assembly on the captain's and first officer's sides of the number 2 windows in the flight compartment. This bulletin also gives instructions to inspect and turn the receptacle connectors on the sidewall panels and covers if necessary. Revision 2 is sent to change the illustrations in Figures 2 and 7 to show the correct station (STA) locations for the coil cord connectors. Boeing Service Related Problem (SRP) 737-SRP-56-0017 is related to this service bulletin. Revision 3 is sent to notify operators that the change in this service bulletin must be done within 48 months after the Revision 3 date of this service bulletin. Revision 4: This revision is sent to give instructions to change the keyway position of the receptacle connectors D10572. Three operators accomplished this service bulletin before this Revision 4 had found that the wire connectors at the two ends of the coil cord rub each other. The rub condition occurs when the window opens or is in the fully open position. The rub condition can possibly cause damage to the wire connector and the coil cord. If the changes added in this Revision 4 is not done, the rub condition can cause part damages and possibly loss of window heat protection.

A General Visual Inspection is defined as: A visual examination of an interior or exterior area, installation or assembly to detect obvious damage, failure or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight or drop-light and may require removal or opening of access panels or doors. Stands, ladders or platforms may be required to gain proximity to the area being checked. 5. These work instructions refer to procedures included in other Boeing documents. When the words "refer to" are used and the operator has an accepted alternative procedure, the accepted alternative procedure can be used. When the words "in accordance with" are included in the instruction, the procedure in the Boeing document must be used. 6. The instructions identified in Paragraph 3.B., Work Instructions and the Figure(s) give the recommended sequence of steps. 7. The work instructions are divided into 2 parts and 2 work packages. Task Hours and Elapsed Hours for each package are given in Paragraph 1.G., Manpower. You can do each part and work package independently. – Part 1- Coil Cord and Wire Connector Changes, Captain's and First Officer's Sides – Part 2, Work Package 1- Receptacle Connector Position Change, Captain's Side – Part 2, Work Package 2- Receptacle Connector Position Change, First Officer's Side 8.
