328 Support Services GmbH, the German subsidiary of U.S.-based Sierra Nevada Corp., has teamed with Duncan Aviation on its latest project—certifying and delivering a full cabin completion on a Finnish-registered Bombardier Challenger 604. Since 2014, 328 has partnered with Duncan on several business aircraft models, and this collaboration, their 31st, had the German company verifying all the engineering data and certifying the modification with a new EASA Part 21 minor change approval. Duncan handled all the production, installation and testing activity at its Battle Creek, Michigan facility.
The project features a new interior with carpeting throughout the flight deck, galley, cabin and entrance hallway, new pilot seats, reupholstered leather cabin seating and a new countertop and sidewalls.

“We are pleased to continue our collaboration with Duncan Aviation and deliver another successful project for a European customer,” said Jörg Gorkenant, COO and head of 328 Design. “We look forward to starting work on some other projects together in 2017.”
