# 747 Service Bulletin

Number: 747-31-2377 

### Summary Date: September 05, 2006 ATA System: 3161 SUBJECT: INDICATING/RECORDING SYSTEMS - Integrated Display System - Software Change (PW Engines)

CONCURRENT REQUIREMENTS
None. BACKGROUND This service bulletin gives instructions to install new integrated display system (IDS) software PW-506 to support SFAR88 certification compliance, the Special Freighter modification program, the Nitrogen Generation System (NGS), and the Horizontal Stabilizer Tank (HST) fuel pump auto-shutoff system. The IDS-506 software provides new or changed Engine Indication and Crew Alerting System (EICAS) messages as given below: 1. Two new Status level messages are added to support SFAR 88 certification compliance for the pump uncommanded-on system. The message will be annunciated when either one of the fuel pump relays remains energized after the pump is selected off. 2. Ten new Status level messages are added and forty eight messages are changed to accommodate the Cargo Smoke Detection System (CSDS) changes required for the Special Freighter modification program. 3. For aircraft converted in the Special Freighter program: The freighter DOOR synoptic has been changed to inhibit the nose cargo door and add the left upper deck door. The escape slide annunciations are changed to accommodate the active doors. The freighter ECS synoptic is changed to delete the crew rest temperature indication. 4. New Status level messages are provided to indicate a degraded nitrogen generation system and an inoperative nitrogen generation system. 5. New Status level messages are provided for the HST fuel pressure switches to indicate a pressure switch stuck in the high pressure state. The pressure switches must operate correctly for the auto-shutoff system to operate correctly. 6. Message logic is changed to correct Autostart nuisance messages. The software is changed to correct an intermittent problem where the wrong EICAS message may be displayed on the auto-snapshot maintenance page. The intermittent problem occurs only on the display; printed or downlinked reports are not affected.September 05, 2006 747-31-2377 BOEING PROPRIETARY - Copyright © Unpublished Work - See page 1 for details. 6 of 23 There are no changes made for Electronic Flight Instrument System (EFIS) displays. Refer to Boeing Service Letter 747-SL-31-087 for added features and changes to the EICAS message list. The incorporation of this service bulletin will provide an alternative method of compliance (AMOC) to paragraph (a) of AD 2001-12-21, paragraph (a) of AD 2001-21-07, paragraph (c) of AD 2002-19-52, paragraph (a) of AD 2002-24-52; paragraph (a)(2)(ii) of AD 2000-12-21, paragraph (d)(1) of AD 2004-10-05, paragraph (d)(1) AD 96-07-09, paragraph (b)(1) AD 91-13-10R1; and paragraph E. of AD 90-09-06. No additional AMOC approval for AD 2002-24-51 is required since paragraph (a) of AD 2002-24-52 explicitly replaces the requirements of paragraph (d) of AD 2002-24-51. ACTION (PRR 81831-55) For airplanes with only Cathode Ray Tube (CRT) Integrated Display Units (IDUs), install new IDS software using diskette set 685-2265-506 in each of the six CRT IDUs and each of the three EFIS/EICAS Interface Units (EIUs). For airplanes with only Liquid Crystal Display (LCD) IDUs, install new IDS software using diskette set 685-2265-506 in each of the three EIUs, and diskette set 831-6546-506 in each of the six LCD IDUs. For airplanes with a mix of CRT and LCD IDUs, install new IDS software using diskette set 685-2265-506 in each CRT IDU and each of the three EIUs, and diskette set 831-6546-506 in each LCD IDU. EFFECTIVITY All 747-400/400F airplanes with PW engines. Refer to Service Bulletin Paragraph 1.A.1 for effectivity. COMPLIANCE Federal Aviation Administration (FAA) Airworthiness Directives 90-09-06, 91-13-10R1, 96-07-09, 2000-12-21, 2001-12-21, 2001-21-07, 2002-19-52, 2002-24-52, and 2004-10-05 are related to this service bulletin. INDUSTRY SUPPORT INFORMATION Boeing warranty remedies are available for airplanes in warranty as of December 6, 2005. Please refer to Paragraph 2.B., Industry Support Information.

All provisions of AD 90-09-06, AD 91-13-10R1, AD 96-07-09, AD 2000-12-21, AD 2001-12-21, AD 2001-21-07, AD 2002-19-52, AD 2002-24-52, and AD 2004-10-05 that are not specifically referenced in the above statement remain fully applicable and must be complied with. 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 examine the work — Time to cure the materials — Time to make the parts — Time to find the tools.
