The de Havilland Canada DHC-3 Otter is a single engine, high wing, propeller driven aircraft. It was conceived to perform the same roles as the previously successful Beaver but was overall a larger plane. Initially named the King Beaver de Havilland began design work in January, 1951. Canadian certification was given in November, 1952. The US Army soon became the largest operator of the aircraft (under the designation U1).
The Otter served as the basis for the very successful, Twin Otter which featured two wing mounted Pratt and Whitney PT-6 turboprops.
Some aircraft were converted to turbine power using a Pratt & Whitney Canada PT6A turboprop. The Walter 601 Turboprop engine, manufactured in the Czech Republic, may also be fitted to the Otter. The PZL radial engine from the Antonov An-2 (a plane that fulfills a very similar role) may also be fitted to the Otter.
