De Havilland Canada DHC-2T Turbo Beaver N1459T De Havilland Canada DHC-2T Turbo Beaver N1459T at Lake Hood Airstrip, Anchorage, Alaska in May 1983.
 
The DHC-2T Turbo Beaver (or DHC-2 Mk III) is ahigh 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-build aircraft were built by De Havilland at Downsview near Toronto and subsequently there have been a number of aftermarket conversions of DHC-2  featuring powerplants ranging from the Wasp Junior radial to the Pratt & Whitney PT6A turboprop.
 
See 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 acquired the design rights and are marketing a version powered by a 680hp PW 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.
