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, comply 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 Bulletins are EAP-701E-31-AT or EAP-701G-31-AV. Boeing Service Letter 767-SL-31-036A is related to this service bulletin. ACTION (PRR B12710, PRR B13451-R) 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 165-686, 688, 691, 693, 694 with General Electric (GE) CF6-80C2 Full Authority Digital Electronic Engine Control (FADEC) engines. The effectivity is broken up into three major groups for convenience of wire changes.July 23, 1998 Revision 4 July 07, 2005 767-31-0091 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 8 of 51
