The De Havilland Aircraft Company of Canada DHC-2T Turbo Beaver (or DHC-2 Mk III) is a high wing, turboprop-powered variant of the DHC-2 Beaver, a rugged, short take-off and landing utility aircraft.
The prototype (CF-PSM-X) was flown for the first time on 30th December 1963.
A total of 60 new aircraft were built by De Havilland Aircraft Company of Canada at Downsview facility, near Toronto and subsequently, there have been a number of aftermarket conversions. These featured powerplants ranging from the Pratt & Whitney Wasp Junior radial to the PT6A turboprop. Featured below is one such example (VH-AAX) having been converted in Australia fitted with a Garrett Airesearch TPE-331-61 engine. This type is informally known locally as the DHC-2/A1 Wallaroo.
Factory-built aircraft have a 28-inch plug in the fuselage, an angular and taller slightly swept vertical fin and, like the original, can operate on wheel, floats, skis and amphibious floats.
Viking Air have now acquired the design rights and are marketing a version powered by a 680hp Pratt & Whitney PT6A-27 engine and 6,000lb maximum weight. At this weight, the maximum cargo load is increased to 2,450lb.
Viking say that in landplane form, the Turbo Beaver operates from unsurfaced ground strips or forest clearings of three hundred metres (1,000 feet) in length. With fuel reserves, operating under Visual Flight Rules (VFR), it carries a load of about half a ton on practical stages for nearly 1,000 kilometres (about 600 statute miles). A cabin extension, providing for extra windows, a large baggage door and a cargo net, is also available. Viking has completed more than 30 Turbo Beaver conversions.
