Textron Aviation Offers FAA-Certified All-Garmin Avionics Retrofit for Early Cessna CitationJet Aircraft
Why It MattersCertified OEM retrofit programs let manufacturers keep ageing light-jet fleets flying with current cockpit technology, tying owners' upgrade spending to the factory's own service network instead of independent avionics shops.
What happened
Textron Aviation has announced an all-Garmin avionics retrofit for Cessna CitationJet aircraft with serial numbers 525-0001 through 0359. The offering follows Supplemental Type Certification from the Federal Aviation Administration (FAA).
The certification extends Textron Aviation's OEM-supported avionics modernization to the earliest CitationJet aircraft and expands the company's investment in supporting legacy Cessna aircraft. The upgrade gives owners and operators access to cockpit technology that is also available on the CJ1 and CJ2.
The Garmin flight deck comprises the G600 TXi flight display, TXi EIS, GTN 750Xi FMS/NAV/COMM and GFC 600 digital autopilot. Features include Stabilized Approach monitoring and aural V-speed alerting during takeoff. Optional upgrades are the GWX 8000 StormOptix weather radar and the GDL 60 datalink for the PlaneSync connected aircraft management system.
Customers can complete the upgrade through Textron Aviation's service network, which combines certification, installation and ongoing support through a single provider. That provider is the same company that designed, manufactured and continues to support the aircraft.
Industry impact & what to watch
Retrofit programs for older light jets show how manufacturers extend the economic life of a fleet they stopped building long ago. A supplemental type certificate for the earliest CitationJet serial numbers means the oldest airframes can carry the same cockpit architecture as later CJ1 and CJ2 aircraft, which narrows the gap between early and later production aircraft in the used market.
The single-provider structure also matters commercially. When certification, installation and support sit with the manufacturer's own service network, avionics spend that might otherwise go to independent shops stays inside the OEM ecosystem, and that is a deliberate strategy rather than an incidental one. For owners, the practical check is whether a given airframe, shop slot and option mix, such as weather radar or the PlaneSync datalink, fit together before committing to downtime.
The next milestone to follow is how the service network schedules installations across the eligible serial-number range, since that determines how quickly the earliest aircraft actually move onto the new flight deck.
