On April 2, 2007, Viking announced that, nineteen years after being discontinued, with 27 orders and options in hand, it was restarting production of the Twin Otter with more powerful Pratt & Whitney Canada PT6A-34/35 engines. The first flight of the Series 400 technical demonstrator took place on October 1, 2008 at Victoria International Airport. In February 2010 the first new production Twin Otter Series 400 equipped with Honeywell's Primus Apex IFR digital flight deck and configured with a commuter interior took its first flight. The DHC-6-400 series Twin Otter design has all around better performance, it includes more power, space, and now can haul up to 4,280 lbs of freight.
