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

None

BACKGROUND

This service bulletin gives instructions to install two warning level indicator lights on the P2-2 center instrument panel in the flight compartment. The installation of these lights will provide a visual indication to the flight crew to be used in conjuction with the existing aural warning horn for cabin altitude and takeoff configuration alerts. The visual warning lights are intended to provide additional notice 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.

As a part of a service bulletin validation program, this change was completed on airplane PW234 by Service Bulletin 737-31A1325 Validation Copy 1 and Installation Deviation Records 737-31A1325-001 through 737- 31A1325-006 before the initial release of this service bulletin. The change completed on airplane PW234 by Service Bulletin 737-31A1325 Validation Copy 1 and Installation Deviation Records 737-31A1325-001 through 737-31A1325-006 is equivalent to the initial release of this service bulletin. Airplane PW234 has the configuration of a Group 13 airplane.

Boeing Service Related Problem (SRP) 737-SRP-31-0042 is related to this service bulletin.

ACTION

Get access to the flight compartment. Remove the P2-2 center instrument panel to install two warning level indicator lights on the panel and change three wire bundles. Reinstall the modified P2-2 center instrument panel. Do a test of the warning level indicator lights.
