Number: 747-31-2378 Summary

Date: September 05, 2006

ATA System: 3161

SUBJECT: INDICATING/RECORDING SYSTEMS - Integrated Display System - Software 

Change (RR Engines)

CONCURRENT REQUIREMENTS

None.

BACKGROUND

This service bulletin gives instructions to install new integrated display system (IDS) software RR-506 to support 

SFAR88 certification compliance, the Special Freighter modification program, the Nitrogen Generation System, 

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 compliancefor 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 accomodate 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.

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-31-088 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)(3)(iii) of AD 2000-02-22, paragraph (d)(1) of AD 2004-10-05, paragraph (d)(1) AD 

96-07-09 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 995-0054-506 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 

995-0054-506 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 995-0054-506 in 

each CRT IDU and each of the three EIUs, and diskette set 831-6546-506 in each LCD IDU.

EFFECTIVITY

F. 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.

This service bulletin has been approved by the FAA. In addition, the Manager of the FAA Seattle 

Aircraft Certification Office approves the action (i.e. inspection or modification) defined in this service 

bulletin as an alternative method of compliance to the requirements of 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 for the no alternate fuel system program pin selected configuration of IDS-506; paragraph 

(a)(3)(iii) of AD 2000-02-22 for Thrust Reversers; paragraph (d)(1) of AD 2004-10-05 for overspeed 

and stall warning; and paragraph (d)(1) AD 96-07-09 for fuel filter bypass; and paragraph E. of AD 90-

09-06 for cargo door latching and status indication. The "Certificate Limitations" contained in FAA 

Letter 140S-06-112 must be substituted in place of the "Certificate Limitations" contained in paragraph 

(a) of AD 2002-24-52 when complying with the requirements of that AD paragraph. All other 

requirements of that AD, including compliance times, remains in force. 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. All provisions of AD 90-09-06, AD 96-07-09, AD 

2000-02-22, 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.
