This Twin Otter was De Havilland Canada's demonstrator with the appropriate registration from roll out June 1976 to January 1977. Delivered to Northern Thunderbird in Febuary 1977, the aircraft was sold to Aklak Air in September 1985. It's still current with Aklak Air at the time of uploading, althought it's been registered to Kenn Borek Air since 1994. The two airrlines entered into an agreement where Aklak could draw from Borek's fleet as demand shifted during seasonal flying.
