IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OWNER. CONCURRENT REQUIREMENTS Refer to Paragraph 1.B., Concurrent Requirements. BACKGROUND This service bulletin gives instructions to remove and replace the P1-3 and P3-1 instrument panels in the flight compartment with panels that include two warning level indicator lights. These indicator lights read "TAKEOFF CONFIG" and "CABIN ALTITUDE". The installation of these lights will provide a visual indication to the flight crew in addition to the existing aural warning horn for cabin altitude and takeoff configuration alerts. The visual warning lights are intended to provide an additional indication to crews to prepare a correct takeoff configuration, respond to excessive cabin altitude and avoid confusion between the takeoff configuration and cabin altitude alerts. An unrecognized incorrect takeoff configuration or excessive cabin altitude could prevent a continued safe flight and landing.

The installation of these lights will provide a visual indication to the flight crew in addition to the existing aural warning horn for cabin altitude and takeoff configuration alerts. The visual warning lights are intended to provide an additional indication to crews to prepare a correct takeoff configuration, respond to excessive cabin altitude and avoid confusion between the takeoff configuration and cabin altitude alerts. An unrecognized incorrect takeoff configuration or excessive cabin altitude could prevent a continued safe flight and landing. Fleet Team Digest (FTD) 737NG-FTD-31-06004 is related to this service bulletin. Boeing Service Related Problem (SRP) 737-SRP-31-0042 is related to this service bulletin. NOTE: Operators may wish to incorporate service bulletin 737-21-1165 concurrently with this service bulletin due to common access requirements. Revision 1 is sent to tell operators that airplanes with the high altitude landing configuration of the Cabin Altitude Warning System are added to this service bulletin effectivity. New Groups 8 through 21 have been created. As a part of a service bulletin validation program, this change was completed on airplane YA010 by Service Bulletin 737-31A1332 Original Issue before the release of Revision 1 of this service bulletin. The change completed on airplane YA010 by Service Bulletin 737-31A1332 Original Issue is equivalent to the release of Revision 1 of this service bulletin. Airplane YA010 has the configuration of a Group 1 airplane. Revision 2 is sent to add the airplanes YJ802-YJ866 to Group 1 of the service bulletin effectivity. Also, this revision will add new BAE Systems component service bulletins and correct errors that were found by operators during the incorporation of Revision 1 of this service bulletin. YC801-YC892 airplanes are moved from Group 1 to a new Group 22. YA571-YA572 airplanes are moved from Group 1 to a new Group 23. As a part of a service bulletin validation program, this change was completed on airplane YG035 by Service Bulletin 737-31A1332 Revision 1 before the release of Revision 2 of this service bulletin. The change completed on airplane YG035 by Service Bulletin 737-31A1332 Revision 1 is equivalent to the release of Revision 2 of this service bulletin. Airplane YG035 has the configuration of a Group 8 airplane. D. Description Group 1-6, 8-12, 16-18, 20: Get access to the flight compartment.
