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.
NOTE: Operators may wish to incorporate service bulletin 737-21-1165 concurrently with this service bulletin
due to common access requirements.
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.
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.

Group 21, Configuration 2:
DescriptionService BulletinCompany
Replaces the basic P5-16 panel with a high
altitude landing P5-16 panel.
737-21-1171 Original IssueBoeing
C. Reason
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.
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.

Revision 3 is sent to advise operators of several changes to the service bulletin. Because the change
given in Figures 48-50 affect wiring changes previously accomplished in Service Bulletin 737-24A1141,
Figures 15-17, airplane line numbers 1-740 are moved to new groups 24-25 and 27-33. New Figures
52- 55 and new sets of work instructions have been created for airplane line numbers 1-740 (existing
Group 2, 4, 16-18 and new Group 24-25, 27-33). Airplanes YD301-YD334 are moved to a new Group
26 because of a different wire configuration. A new Figure 56 is created for Group 26 airplanes. YA630
is moved from Group 1 to Group 12 because this airplane was modified by the MR to a High Altitude
cabin pressure warning configuration.
Also, Weight and Balance information is clarified for Group 4 and Group 7 airplanes. CMM references
for BAE panel assemblies have changed. Group 7 airplanes are added to work instruction steps and
a new wire routing Figure 51 is added for Group 7 airplanes. References list has been changed. Also,
a note in Figure 11 of the service bulletin has changed to remove an incorrect wire number reference.
Revision 4 is sent to advise operators of several changes to the service bulletin. Airplanes YA091-YA097
were added to Group 1 of this service bulletin effectivity because they were incorrectly removed from
Revision 3. The airplane YG001 has been moved from Group 2 to Group 31. Manpower estimates
have changed to include an additional time for the removal of the forward galley, and the removal of
the drip shield, the airstair assembly and the airstair door for airplanes that have airstairs installed. A
new BAE Systems component service bulletin 233A2222-31-06 has been added. For Group 15, 19
and 21 airplanes, FIGURE 37 and FIGURE 43 have been changed because these airplanes do not
need to install the R1044 and the associated wiring. FIGURE 34, 36 and 44 have been changed to
add the W2508-0032-22 wire. Also, the FAA Airworthiness Directive AD 2013-02-05 has been added
to the service bulletin.

time:
 Time to adjust to the workplace
 Time to schedule the work
 Time to inspect the work
 Time to cure the materials
 Time to make the parts
 Time to find the tools.
