The program for preowned Excels includes a Garmin G5000 integrated flight deck. The Cessna Citation Excel Eagle brings an updated flight deck, interior, and exterior to the 23-year-old Excel series. CitationPartners A trio of former Cessna Aircraft Company executives has joined forces to launch a program to rehabilitate and upgrade legacy Cessna Citation Excel jets, first certified in April 1998 and precursors to the Citation XLS that debuted in 2004. The group, CitationPartners LLC, based in Wichita, Kansas, has christened the refurbished mid-sized jets âCitation Excel Eagles.â Former Cessna chairman Russ Meyer, former Cessna CEO Gary Hay, and former Citation CJ3 and Mustang program manager Russ Meyer III will oversee the transformation, which includes an update to the Garmin G5000 integrated flight deck up front, and a new interior and exterior. A long list of parts and upgraded systems will be installed by the Citation Service Center at Wichita Dwight D. Eisenhower Airport (KICT). Longtime Cessna partner and parts-and-service expert Yingling Aviation will install the G5000 and complete additional work on the Excel Eagles to finish out the total package.
