Original Issue: September 11, 2009

ATA System: 3141

SUBJECT: INDICATING/RECORDING SYSTEMS - Engine Indication and Crew Alerting System

(EICAS) - EICAS Operational Program Software (OPS) Change

BOEING RECOMMENDS THAT EACH OPERATOR EXAMINE THIS SERVICE BULLETIN IMMEDIATELY.

CONCURRENT REQUIREMENTS

Refer to Paragraph 1.B., Concurrent Requirements.

BACKGROUND

This service bulletin gives instructions to install new Operational Program Software (OPS) Version 7, in the left

and right Engine Indication and Crew Alerting System (EICAS) computers. Accomplishment of this service

bulletin will put back the missing EICAS advisory level messages "L ENG FUEL FILT" that was not included in

the EICAS OPS, Version 6. The EICAS OPS Version 7 includes all the improvements that were given in EICAS

OPS Version 6. If this service bulletin is not done for airplanes with EICAS OPS Version 6 installed, the EICAS

will not show an advisory message to the flight crew of a possible left engine fuel filter bypass condition. Fuel

contamination could cause a sudden engine thrust loss or an engine malfunction event, and could subsequently

cause an in-flight shutdown of an engine.

An operator reported that during a scheduled maintenance of an airplane with EICAS OPS Version 6 installed,

the operator tried to do a test of the engine fuel filter impending bypass indication. During the test of the number

2 engine, both the EICAS advisory and status level messages "R ENG FUEL FILT" were shown correctly. But

on number 1 engine, only the EICAS status level message "L ENG FUEL FILT" was shown. No EICAS advisory

level message "L ENG FUEL FILT" was shown.

Refer to Boeing Service Letter 757-SL-31-045 for more details about this change.

The new software will change the operational procedures for the airplane. Refer to APPENDIX A, Software

Accomplishment Summary, for more data about this change.

Boeing Service Related Problem (SRP) 757-SRP-31-0046 is related to this service bulletin.

Fleet Team Digest 757 FTD 31-08001 and 757 FTD 31-08002 are related to this service bulletin.

ACTION (PRR 54530-286RS)

Install new EICAS OPS in the left and right EICAS computers.

The related service bulletin (SB) is Rockwell Collins SB EICAS-31-6. The Rockwell Collins SB EICAS-31-6 gives

instructions to change the EICAS OPS for spare EICAS computers.

Necessary for Each Airplane. If any parts or components are found, refer to Paragraph 2.C. for

the recommended use.

B. Concurrent Requirements

The service bulletin(s) listed below must be done before or at the same time as this service bulletin:

Group 2:

Company Service Bulletin Description

Boeing 757-31-0105 Original Issue Changes the EICAS OPS for 757-300 airplanes.

Group 3:

None.

C. Reason

This service bulletin gives instructions to install new Operational Program Software (OPS) Version 7,

in the left and right Engine Indication and Crew Alerting System (EICAS) computers. Accomplishment

of this service bulletin will put back the missing EICAS advisory level messages "L ENG FUEL FILT"

that was not included in the EICAS OPS, Version 6. The EICAS OPS Version 7 includes all the

improvements that were given in EICAS OPS Version 6. If this service bulletin is not done for airplanes

with EICAS OPS Version 6 installed, the EICAS will not show an advisory message to the flight crew

of a possible left engine fuel filter bypass condition. Fuel contamination could cause a sudden engine

thrust loss or an engine malfunction event, and could subsequently cause an in-flight shutdown of an

engine.

BOEING SERVICE BULLETIN 757-31-0192
An operator reported that during a scheduled maintenance of an airplane with EICAS OPS Version 6

installed, the operator tried to do a test of the engine fuel filter impending bypass indication. During the

test of the number 2 engine, both the EICAS advisory and status level messages "R ENG FUEL FILT"

were shown correctly. But on number 1 engine, only the EICAS status level message "L ENG FUEL

FILT" was shown. No EICAS advisory level message "L ENG FUEL FILT" was shown.

Refer to Boeing Service Letter 757-SL-31-045 for more details about this change.

The new software will change the operational procedures for the airplane. Refer to APPENDIX A,

Software Accomplishment Summary, for more data about this change.

Boeing Service Related Problem (SRP) 757-SRP-31-0046 is related to this service bulletin.

BOEING SERVICE BULLETIN 757-31-0192
E. Compliance

Federal Aviation Administration (FAA) Airworthiness Directives (AD) 96-07-09, 2004-10-05 and

2008-09-07 are related to this service bulletin.

Boeing recommends that for airplanes with EICAS OPS Version 6 installed, the change given in this

service bulletin be done within 90 days after the original issue date of this service bulletin.

F. Approval

This service bulletin was examined by the FAA. The changes specified in this service bulletin comply

with the applicable regulations and are FAA approved, as well as European Aviation Safety Agency

(EASA)/Joint Aviation Authorities (JAA) approved for all EASA/JAA approved airplanes listed in the

service bulletin effectivity. This service bulletin and its approval were based on the airplane in its original

Boeing delivery configuration or as modified by other approved Boeing changes.

If an airplane has a non-Boeing modification or repair that affects a component or system also affected

by this service bulletin, the operator is responsible for obtaining appropriate regulatory agency approval

before incorporating this service bulletin.

This service bulletin has been approved by the FAA. In addition, the Manager of the FAA Seattle Aircraft

Certification Office approves the installation of new EICAS OPS Version 7, as described in this service

bulletin, as an alternative method of compliance (AMOC) to the requirements of paragraph (d)(1) of

AD 96-07-09 and paragraph (d)(2) of AD 2004-10-05. All provisions of AD 96-07-09 and AD 2004-10-05

that are not specifically referenced in the above statement remain fully applicable and must be complied

with.

The installation of EICAS OPS Version 7 terminates the airplane flight manual (AFM) Limitations

required by paragraph (f) of AD 2008-09-07 and is a means of compliance for paragraph (g) of AD

2008-09-07. No AMOC is necessary for AD 2008-09-07. When all affected airplanes in an operator's

fleet have been verified by the operator to have EICAS computer part number S242N701-1001 and

only EICAS OPS versions other than Version 6 software that are FAA approved for that airplane, then

the associated revisions to the Limitations section of the AFM required by paragraph (f) of AD 2008-09-07

may be removed from the AFM.

G. Manpower

The table below shows an estimate of the task hours necessary to do this change for each airplane.

This estimate is for direct labor only, done by an experienced crew. Adjust the estimate with operator

task hour data if necessary. The estimate does not include lost time. These are some examples of lost

time:

• Time to adjust to the workplace

• Time to schedule the work

• Time to inspect the work

• Time to cure the materials

• Time to make the parts

• Time to find the tools.
