SUBJECT:INDICATING/RECORDING SYSTEMS - Central Computers - Engine Indication And Crew Alerting System - EICAS Computer Replacement And Wire Change - Pratt and Whitney 4000 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, 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-701D-31-AR or EAP-701G-31-AV. 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 PW4000 Full Authority Digital Electronic Engine Control (FADEC) engines. The effectivity is broken up into four 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. INDUSTRY SUPPORT INFORMATION Boeing warranty remedies are not available for the configuration changes given in this service bulletin. MANPOWER Total Man-hours Elapsed Time 14.0 7.0 The change to the EICAS computers as given in the Rockwell/Collins service bulletins are not included. MATERIAL INFORMATION Operator Supplied Parts
