In 2005, Viking purchased the Type Certificates for all of the out-of-production de Havilland aircraft (DHC-1 through DHC-7), including the Twin Otter. After an extensive market analysis was conducted, it was determined that an overwhelming demand existed to bring the Twin Otter back into production, thus the Viking Series 400 Twin Otter Production Program was announced in 2007. The first production aircraft was delivered in 2010 and by mid 2015, 75 of the new series had been delivered.The Series 400 Twin Otter picks up where the original de Havilland Series 300 Twin Otter left off, introducing upgraded Pratt & Whitney PT6A-34 engines, fully integrated Honeywell Primus Apex digital avionics suite, internal and external LED lighting, and approximately 800 other modifications incorporated to improve upon the original production model.However, like its predecessor, the Series 400 Twin Otter retains the ability to operate economically, safely and reliably from remote and unimproved airfields due to its robust design, equalized maintenance program and dependability of the Pratt & Whitney engines.
