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.
