In the works: Viking Aircraf, DHC-6-400 Twin Otter

Viking Aircraft’s modern upgrade of the Twin Otter has entered the final phase of testing and is slated for certification shortly. The program did suffer minor delays in the certification schedule and first deliveries have been moved from late this year to early next year. Initial certification will be by Transport Canada and the EASA.
The -400 is undergoing final checkouts for landplane, tundra tire, skiplane, floatplane and amphibious float configurations. Viking Aircraft has completed FAR Part 36 noise testing in both the landplane and amphibious float configurations as well as “hot temperature testing to validate hardware performance in extreme temperatures.” Seven-400 Twin Otters are currently in production, and Viking plans to deliver 12 airplanes next year.
