CONCURRENT REQUIREMENTS
None
BACKGROUND
This service bulletin gives instructions to replace the
two Engine Indication and Crew Alerting System
(EICAS) computers. The new computers allow
loadable Operational Program Software (OPS) and
Operational Program Configuration (OPC) software
installation via a portable data loader (PDL) or an
airborne data loader (ADL).
The new EICAS computers allow the use of OPC
software to change the configuration of options
selected by the customer. Loadable OPC software
eliminates the requirement to change program pin
wiring to make customer options.
The new EICAS computers have increased
capacity, supports optional Future Air Navigation
System (FANS) features, complies with Amendment
No. 121-266 [Docket No. 28109], "Revisions to
Digital Flight Data Recorder Rules", and in
combination with the appropriate Airplane Flight
Manual (AFM) revision to Section 3.2, in accordance
with Airworthiness Directive (AD) 96-07-09
paragraph (d)(2), will provide terminating action for
the fuel filter bypass AD 96-07-09.
The related Rockwell/Collins Service Bulletin is
EAP-701B-31-AN.
Boeing Service Letter 767-SL-31-036 is related to
this service bulletin.
ACTION (PRR B12710)
In the E8 rack, replace the left and right EICAS
computers. Make wire changes in the E8 shelf.
Change left and right EICAS computer connector
keying on the E-8 shelf. Load OPC software into
both left and right EICAS computers. Do an
operational test of the EICAS computers.
EFFECTIVITY
All 767 airplanes line positions 1 - 695 with General
Electric (GE) Power Management Computer (PMC)
engines.
The effectivity is broken up into seven major groups
for convenience of wire changes.
COMPLIANCE
Federal Aviation Administration (FAA) Airworthiness
Directive 96-07-09, Amendment 39-9558, is related
to this service bulletin.

B. Concurrent Requirements
None
C. Reason
This service bulletin gives instructions to replace the two Engine Indication and Crew Alerting System
(EICAS) computers. The new computers allow loadable Operational Program Software (OPS) and
Operational Program Configuration (OPC) software installation via a portable data loader (PDL) or an
airborne data loader (ADL).
The new EICAS computers allow the use of OPC software to change the configuration of options
selected by the customer. Loadable OPC software eliminates the requirement to change program pin
wiring to make customer options.
The new EICAS computers have increased capacity, supports optional Future Air Navigation System
(FANS) features, complies with Amendment No. 121-266 [Docket No. 28109], "Revisions to Digital
Flight Data Recorder Rules", and in combination with the appropriate Airplane Flight Manual (AFM)
revision to Section 3.2, in accordance with Airworthiness Directive (AD) 96-07-09 paragraph (d)(2),
will provide terminating action for the fuel filter bypass AD 96-07-09.
The related Rockwell/Collins Service Bulletin is EAP-701B-31-AN.
Boeing Service Letter 767-SL-31-036 is related to this service bulletin.
Revision 1 is sent to make changes to the EICAS functional test and the Parts Necessary for Each
Airplane section 2.C.
Revision 2 is sent to change left program pins, supplemental pins, OPC software part numbers and
diskette set part numbers in Appendix A. Appendix B and C was changed to add the new Group 7
airplanes.
D. Description
In the E8 rack, replace the left and right EICAS computers. Make wire changes in the E8 shelf.
Change left and right EICAS computer connector keying on the E-8 shelf. Load OPC software into
both left and right EICAS computers. Do an operational test of the EICAS computers.
NOTE: Some service bulletins with EICAS program pin changes are not usable after this change is
done. Operators must contact Boeing for the OPC diskette that accomplishes the equivalent
of those program pin changes.
The changes in this service bulletin will change the Engine Indication and Crew Alerting System
(EICAS).
Revision 1 - No more work is necessary on airplanes changed as shown in the initial release of this
service bulletin. The EICAS functional test was changed with the addition of two new steps on page
14 and to show the correct circuit breaker name, location and numbers on pages 12, 13 and 14.
Revision 2 - More work is necessary on airplanes VB051-VB054, VN307-VN314 and VN676 changed
as shown in the initial release or in Revision 1 of this service bulletin. In addition, airplanes
VK046-VK054 were moved from Group 2 into a new Group 7. In Appendix A, the following were
changed: left program pins, supplemental pins, OPC software part numbers and diskette set part
numbers. Appendix B and C was changed to add the new Group 7 airplanes.
An evaluation form is attached to this service bulletin. Please use this form to tell us what you think
of the quality of this service bulletin.

3. ACCOMPLISHMENT INSTRUCTIONS
GENERAL NOTES
1. The paragraphs identified with a letter give the general work instructions and the necessary tests.
The instructions identified with numbers on the figures give the recommended sequence of steps.
2. Refer to the Boeing Standard Wiring Practices Manuals 20-10-11 and 20-10-12 for the wire
installation procedures.
3. Obey all of the warnings and cautions given in the specified manual sections.
4. Airplanes with an EICAS three crew configuration (VB051 - VB055) must be changed to a two
crew configuration prior to making the changes in this service bulletin.
5. Some service bulletins with EICAS program pin changes are not usable after this change is done.
Operators must contact Boeing for the OPC diskette that accomplishes the equivalent of those
program pin changes.
6. The Accomplishment Instructions are divided into two parts as follows:
- Part I - Instructions to compare the EICAS readouts to those given in Appendix A. You can now
make sure the applicable software is used for this change.
- Part II - Instructions to replace the EICAS computers, make wire changes and load the new
software.
WORK INSTRUCTIONS
PART I - EICAS READOUT COMPARISON
A. On the P9 panel, move the EICAS DSP "COMPUTER" switch to "L".
B. On the P61 panel, press the EICAS MAINT Panel "CONF/MCDP" button.
C. Compare the "PROG PINS" and "SUPL PINS" readouts displayed on the lower EICAS display
with the LEFT PROG PINS and SUPL PINS information in Appendix A for the applicable
effectivity. If the EICAS readouts do not agree with those given in Appendix A, supply the PROG
PINS and SUPL PINS data to the Boeing Company to get the correct OPC software part number.
NOTE: For airplanes with EICAS part number S242N701-401 through -406, the "SUPL PINS"
readout is not applicable. It is only necessary to make sure that the left EICAS PROG
PINS readout agrees with Appendix A.
D. On the P9 panel, move the EICAS DSP "COMPUTER" switch to "AUTO".
PART II - SOFTWARE LOADABLE EICAS COMPUTER CHANGE
A. Remove the electrical power from the airplane circuits as given in 767 AMM Subject 24-22-00.
Attach DO-NOT-CLOSE tags to opened circuit breakers and DO-NOT-OPERATE tags to
applicable switches. Use an independent power source for lighting.
B. Remove the left and right EICAS computers as shown in Figure 1.
C. Make W1035 wire changes as shown in Figure 2.
D. Make W1037 wire changes as shown in Figure 3.
