## Description Group 1-2: 1. CONCURRENT REQUIREMENTS Refer to Data Module SB B787-A-27-00-0023-00A-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), FCM Air Data Reference Function (ADRF) DB, and Central Maintenance Computer Function (CMCF) LDI DB software to correct deficiencies in the following areas: – Nuisance unwanted post flight or initiated test failures under unusual operating conditions or with some pre-existing failures – Fixes for difficulties gathering fault data, or doing detailed troubleshooting with initiated test capabilities on airplanes in service – Misleading, extra, or missing fault reports that can lead to the mechanic not being given satisfactory data on what components to change – Address when initiated tests either cannot be run, or require time consuming procedures when some pre-existing failures are present – Nuisance advisory Engine-Indicating and Crew-Alerting System (EICAS) messages requiring inspections and system tests before further airplane dispatch – Correct nuisance issues in the Air Data Reference Function (ADRF) – Nuisance disconnect of the Autopilot Column Backdrive– Nuisance indications of NO LAND 3, NO AUTOLAND, and AUTOFLIGHT FUNCTION status and advisory messages.
If the changes in this service bulletin are not done, the FCE software may 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, and could cause intermittent indications in the flight deck.

See title page for details. B787-81205-SB270023-00 Issue 001, 24 Jul 2014 AIRCRAFT SERVICE BULLETIN– Misleading, extra, or missing fault reports that can lead to the mechanic not being given satisfactory data on what components to change – Address when initiated tests either cannot be run, or require time consuming procedures when some pre-existing failures are present – Nuisance advisory Engine-Indicating and Crew-Alerting System (EICAS) messages requiring inspections and system tests before further airplane dispatch – Correct nuisance issues in the Air Data Reference Function (ADRF) – Nuisance disconnect of the Autopilot Column Backdrive– Nuisance indications of NO LAND 3, NO AUTOLAND, and AUTOFLIGHT FUNCTION status and advisory messages.
If the changes in this service bulletin are not done, the FCE software may 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, and could cause intermittent indications in the flight deck. Boeing Service Related Problem (SRP) 787 SRP-27-0249 is related to this service bulletin. 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), FCM Air Data Reference Function (ADRF) DB, and Central Maintenance Computer Function (CMCF) LDI DB software, and do a software configuration check. The work in this service bulletin is done in the maintenance zone(s) given below. Table 6 Affected Maintenance Zones Zone Model 117, 145, 211, 222 787-8 5. Compliance Boeing recommends that the change given in this service bulletin be done within 12 months after the Issue 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 EuropeanAviation 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.

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.

2. WORK INSTRUCTIONSA. Make sure that the service bulletin(s) given in Data Module SB B787-A-27-00-0023-00A-932A-D, Paragraph 2., Concurrent Requirements has/have been accomplished. B. Supply electrical power to the airplane. Refer to 787 AMM 24-22-00 as an accepted procedure. C. Install each instance of the software listed in the Loadable Software Attributes, as applicable, and do a software check. Refer to 787 AMM 45-13-00 and 787 AMM 46-13-00 as an accepted procedure. NOTE: The procedure for staging software on a Mass Storage Device (MSD) is provided for reference only. The operators can use their own procedure to stage the software on the MSD(s). Boeing recommends that operators maintain the latest software on the MSD(s) so that it is available if the software should become necessary, such as due to an unplanned component change. Refer to Boeing Service Letter 787 SL-00-003 for more information.
