Attention Challenger 604 Owners / Operators:

As of December 2021, Collins Aerospace began repairing all Challenger 604 CRT units with “used” parts and after December 2023 the EFD-4077 will no longer be supported. All other cockpit Challenger 604 CRTs will become obsolete shortly thereafter.

In September 2020, Collins announced the impending obsolescence of Pro Line 4 CRT screens, along with the boxes that house the screens. Today, these screens are no longer being made and repairs are being processed by Collins with used parts.

The complexity and cost of repairs is expected to rise as preowned stock is depleted. Once the stock of available screens at Collins or in the aftermarket stock is gone, if you have a failure, your plane will be grounded immediately.

Along with screen obsolescence issues, the FMS itself in the Pro Line 4 system will not be able to support the ever-increasing demands of the modern and future airspace. Your best option is to upgrade to the new Collins Pro Line Fusion®.
