Service Bulletin

Number: 767-31-0101 Summary Date: July 6, 2000

ATA System: 3141

SUBJECT: INDICATING/RECORDING SYSTEMS - Central Computers - Engine Indication And Crew

Alerting System - EICAS Computer Replacement And Wire Change - Pratt And Whitney

JT9D-( ) Engines

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, support optional Future Air Navigation

System (FANS) features, and comply with

Amendment No. 121-266 [Docket No. 28109],

"Revisions to Digital Flight Data Recorder Rules".

The related Rockwell/Collins Service Bulletin is

EAP-701A-31-AM.

Boeing Service Letter 767-SL-31-036A is related to

this service bulletin.

ACTION (PRR B12710, PRR B13058)

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 EICAS OPS and OPC

software into both left and right EICAS computers.

Do an operational test of the EICAS computers.

EFFECTIVITY

All 767 airplanes line positions 1 - 329 with Pratt and

Whitney JT9D-( ) engines.

The effectivity is broken up into three major groups

for convenience.

COMPLIANCE

No compliance time is given.

INDUSTRY SUPPORT INFORMATION

Boeing warranty remedies are not available for the

configuration changes given in 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 and 20-10-19 for wire separation.

3. Obey all of the warnings and cautions given in the specified manual sections.

4. 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.

5. The Accomplishment Instructions are divided into two parts as follows:

- Part I - Instructions to compare the EICAS readouts to those given in Appendix A are given.

These instructions will 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 are given.

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 numbers S242N701-301 through -306, 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.
