Description

Group 1-2:

1. CONCURRENT REQUIREMENTS

Refer to data module Data Module SB B787-A-27-00-0020-00A-932A-D, Paragraph 2., Concurrent Requirements.

2. BACKGROUND

This service bulletin gives instructions to install Flight Control Module (FCM) Operational Program Software

(OPS), FCM Loadable Diagnostic Information (LDI) Database (DB), and FCM Air Data Reference Function

(ADRF) DB software. Accomplishment of this service bulletin will make sure that the in-service findings associated to Flight Control Electronics (FCE) Block Point 2 are eliminated, and that the Flight Control Electronics (FCE) Block Point 2 software functions as originally intended. If the changes in this service bulletin

are not done, the Flight Control Electronics (FCE) Block Point 2 software will not function as originally intended,

which could result in deficiencies in the control law and maintenance areas which could result in nuisance

EICAS and Maintenance messages. In addition, accomplishment of this service bulletin will correct a deficiency in the control law area which could lead to reduced controllability of the airplane.

This table is provided to operators for planning purposes only. Refer to the applicable sections for more information.

Flight Controls - Primary Flight Control

Function - Flight Control Electronics Block

Point 2*[1]

Boeing SB B787-81205-SB270017-00 Issue 001

*[1] Use the Onboard Data Load Function (ODLF) to install Flight Control Module (FCM) Operational Program Software (OPS), FCM

Loadable Diagnostic Information (LDI) Database (DB), and Central Maintenance Computer Function (CMCF) LDI DB software, or at

a minimum install the FCM LDI DB and CMCF LDI DB software, in accordance with the Accomplishment Instructions of Boeing Alert

Service Bulletin B787-81205-SB270017-00, Issue 001, dated September 18, 2013.

Group 1:

Service bulletin (SB) SB B787-81205-SB270017-00 Issue 001 will make sure that the new Flight Control

Module (FCM) Operational Program Software (OPS), FCM Loadable Diagnostic Information (LDI) Database

(DB) and Central Maintenance Computer Function (CMCF) LDI DB correct deficiencies in the monitoring

and maintenance areas which could result in nuisance messages.

Group 2:

None.

Group 1-2:

3. Reason

This service bulletin gives instructions to install Flight Control Module (FCM) Operational Program Software

(OPS), FCM Loadable Diagnostic Information (LDI) Database (DB), and FCM Air Data Reference Function

(ADRF) DB software. Accomplishment of this service bulletin will make sure that the in-service findings

associated to Flight Control Electronics (FCE) Block Point 2 are eliminated, and that the Flight Control

Electronics (FCE) Block Point 2 software functions as originally intended. If the changes in this service

bulletin are not done, the Flight Control Electronics (FCE) Block Point 2 software will not function as originally intended, which could result in deficiencies in the control law and maintenance areas which could

result in nuisance EICAS and Maintenance messages. In addition, accomplishment of this service bulletin

will correct a deficiency in the control law area which could lead to reduced controllability of the airplane.

4. Description

Use the Onboard Data Load Function (ODLF) to install Flight Control Module (FCM) Operational Program

Software (OPS), FCM Loadable Diagnostic Information (LDI) Database (DB), and FCM Air Data Reference

Function (ADRF) DB software, and do a software configuration check.

The work in this service bulletin is done in the maintenance zone(s) given below.

001 date of this service bulletin.

6. Approval

This service bulletin was examined by the Federal Aviation Administration (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.

7. 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

This estimate gives general service bulletin incorporation time. The specific software data transfer times

can change the estimate given in the table.

This estimate does not include the task hour data given in the service bulletins in Paragraph 2., Concurrent

Requirements.

and the Special Tool and Ground Handling Drawing Index contain data on versions of the tools

or test equipment that you can use. It is permitted to use replaced tools. It is not permitted to

use superseded tools.

8. If it is necessary to remove more parts for access, you can remove those parts. If you can get

access without removing identified parts, it is not necessary to remove all of the identified parts.

Jacking and shoring limitations must be observed.

9. If shading is used, shaded areas in Figures are to separate the non-critical and non-authoritative

information from the critical and authoritative information.

10. Some steps in the Work Instructions are identified as Required for Compliance (RC). If this

service bulletin is mandated by an Airworthiness Directive (AD), then the steps identified as RC

must be done to comply with the AD. Alternative procedures for steps not identified with RC can

be used if the RC steps can still be done as specified, and the airplane can be put back to a

serviceable condition. An Alternative Method of Compliance (AMOC) is not necessary for deviations to steps that are not identified as RC.

software from their Loadable Software Airplane Part Library server directly to the MSD(s). Boeing recommends that operators maintain

the latest software in the MSD(s) so that it is available if the software should become necessary, such as due to an unplanned component change.

*[6] If the MSD-2 is installed on the airplane, the software is loaded to MSD-2 automatically the next time the airplane is in air mode.

(2) RC - Load 27 FCM OPS to the left FCM on the airplane using the ODLF. Refer to 787 AMM 45-13-

(a) If the 27 FCM OPS software part number HNPC-AL01-5012 did not successfully load to the left

FCM on the airplane.

1) Load 27 FCM OPS, 27 FCM LDI DB, and 27 FCM ADRF DB concurrently to the left FCM

on the airplane using the ODLF. Refer to 787 AMM 45-13-00 as an accepted procedure.

NOTE: One FCM needs to stay out of loader mode in order to provide the interlocks necessary for the On Board Data Loading system to stay in loading mode.
