## 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 nuisanceEICAS 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.

*[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 servicebulletin 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.

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

*[1] This software part number is used in production. *[2] Do not install previous versions of this software after installation of the new software part number. *[3] The existing software part number is HNP5E-AL01-5010 or HNP5F-AL01-5011. *[4] Boeing provided loadable software. *[5] The procedure for staging software on a Mass Storage Device (MSD) is provided for reference only. The operators can stagethe 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 unplannedcomponent 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 inair mode. (2) RC - Load 27 FCM OPS to the left FCM on the airplane using the ODLF. Refer to 787 AMM 45-13- 00 as an accepted procedure.

(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.
