Commercial Airplanes 737 Service Bulletin ALERT SummaryNumber: 737-31A1332Original Issue: January 07, 2010 Revision 4: October 31, 2013 ATA System: 3100 SUBJECT: INDICATING / RECORDING SYSTEMS - Aural Warning System - Installation of the Cabin Altitude Warning System and Takeoff Configuration Warning System Lights
THIS BULLETIN IS SENT TO THE OPERATORS OF RECORD OF THE AIRPLANES SHOWN IN PARAGRAPH
1.A., EFFECTIVITY. 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.
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.
