Effectivity: Global 5000 Vision, Global 6000, and Challenger 605 aircraft

ATA 44

Cabin Management System (CMS) VENUE™ must be informed of the latest technical improvements available and applicable to DUAL BLU-RAY DISC PLAYER (DBDP) part number 441-0089-100/-101. Operators shall comply with the following optional vendor Service Bulletins (SB) if they experience the following conditions:

• Displays flashing LED rendering unit inoperative;

• Random audio tic and static.

As a permanent solution, CA issued these SBs:

1. SB 441-0089-44-13 - DBDP FLASHING LIGHT EMITTING DIODE (LED) FAULT - MOD 13 that addresses inoperative issue due to a short circuit in a transistor.

2. SB 441-0089-44-11 DBDP - AUDIO TICK AND STATIC IMPROVEMENT - MOD 11 that implements a hardware modification while SB DBDP-6000-44-2 SOFTWARE UPDATE FOR AUDIO TICK AND LOUD STATIC implements a software update applicable for the CES only. When incorporated together, it addresses the potential of tickling or static noise on Ethernet audio.

When replacing a DBDP on a CES aircraft, the technician must first confirm via the Galley Touchscreen Maintenance Configuration page, that the reference number of the DBDP application 810-0307-013 is installed (Fig.1.).

It is extremely important to make this verification before installing a DBDP modstrike 11 and subs. The procedure for loading the software for this DBDP application can be found in the CA SB DBDP-6000-44-2.

Installing this unit into a CES-5000/6050 Cabin System with the incorrect CES DBDP software P / N will cause the unit to become immediately defective resulting in having to be returned to CA repair centers. CA added a warning notice that comes with spare units to inform technicians about this compatibility requirement.

Operators experiencing DBDP issues shall verify whether the affected DBDP is equipped with the latest available upgrades (Table 1).
