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.

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.
