Duncan Aviation teamed with Germany’s 328 Support Services to complete and certify a full cabin refurbishment on a Finnish-registered Bombardier Challenger 604. The project installed gray carpet throughout the flight deck, galley, cabin and entrance hallway; flight deck crew seats and an entry jump seat; reupholstered cabin and conference seating; and matching upper sidewall and window panels.

The German company was responsible for verifying all the engineering data involved in the project as well as certifying the modification with a new EASA Part 21 minor change approval, while Duncan Aviation handled all the production, installation and testing activity at its facility in Battle Creek, Mich. This marks the 31st project on which 328 and Duncan have collaborated since they established the relationship in 2014, according to Jörg Gorkenant, COO and head of 328 Design.
