# 767 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. MANPOWER Total Man-hours Elapsed Time (Hours) 9.50 4.75 The change to the EICAS computers as given in the Rockwell/Collins service bulletin is not included.

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. 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. Gain access to the E8 shelf in the main equipment center. C. Remove the left and right EICAS computers as shown in Figure 1. D. Remove and/or tape and stow W1035 wires, even if they are installed at locations other than shown in Figure 2. E. Make changes to W1037 wires, if installed as shown in Figure 3.
