Otter 454 was delivered to the Tanzanian Air Force on 12th April 1966 with serial JW 9104. It remained in Canada under the care of the RCAF until May 1967, when it was crated and shipped to Tanzania, where it was re-assembled and entered service, based at Dar es Salaam. The history of the Tanzanian Otters has been explained in relation to Otter 451. Of the eight Otters, three were retained in Canada for training purposes and the other five, including JW 9104, went to Tanzania and continued in service there until April 1972, when these five Otters were purchased by Bannock Aerospace Ltd., of Toronto, Ontario.

The five Otters were flown from Dar es Salaam to Nairobi-Wilson airfield in Kenya in April 1972 and during May were prepared for the long ferry flight back to Canada. They were registered to Bannock Aerospace Ltd., JW 9102 (452) becoming CF-DIO; JW 9103 (453) CF-DIV; JW 9104 (454) CF-DIY; JW 9106 (459) CF-DJA and JW 9107 (460) CF-DIZ. Four of these Otters passed through Shannon in Ireland on the delivery flight home, the fifth (CF-DIY) passing through Prestwick in Scotland. Its full routing was Nairobi (Wilson)-Cairo-Heraklion-Rome-Ashford (England)-Fairoaks (England, to rectify a battery problem)-Prestwick (on 3rd June 1972)-Reykjavik-Narssarssuaq (Greenland)-Gander-Toronto.

After overhaul, on 28th July 1972 CF-DIY was sold on to B.C.Yukon Air Service Ltd., of Watson Lake, Yukon. It went on to fly for this company for seventeen years, later re-registered C-FDIY. In April 1989 it was sold to Temsco Helicopters Inc., of Ketchikan, Alaska registered N28TH. It flew as part of Temsco's large fleet of Otters out of its Ketchikan base until October 1991, when Temsco announced abruptly that its final services would take place on 1st November 1991 and that the airline's fixed wing division would close down on that date. After a period lying idle, the Otter was sold in March 1993 to Alaska Juneau Aeronautics Inc., trading as “Wings of Alaska” and made the short move north from Ketchikan to Juneau, flying as part of the Wings of Alaska fleet, on it scheduled services and particularly on its summertime charters out of Juneau for cruise ship passengers. For nearly six years it retained the registration N28TH but in January 1999 it was registered N339AK in the 'Wings of Alaska' sequence. In April 2002 it was registered to Alaska Coastal Airlines Inc., Juneau but continued flying as part of the Wings of Alaska fleet.

During 2004, Wings of Alaska arranged to convert its Otter fleet to the Texas Turbine conversion with the Garrett TPE-331 engine. Some of this work was carried out at the company's Juneau base, where personnel from Texas Turbine attended to assist. In the case of N339AK, its wings and piston engine were removed at Juneau, and it was shipped in a crate (along with N338AK) to Vernon, BC where both Otters arrived mid October 2004. Here Kal-Air carried out the actual installing of the turbine engine, before the Otter was shipped back to Juneau where the conversion work would be completed over the winter of 2004 / 2005.
