First all-metal bush plane designed and built in Canada; de Havilland Canada DHC-2 Beaver is a single-engined, high-wing, propeller-driven, STOL aircraft developed by de Havilland Canada. The Beaver had extra wide doors so it could be loaded and unloaded easily. It also boasted an accessible oil reservoir that could be refilled in flight.

Developing nation: Canada.
Manufacturer/designer:
de Havilland Canada.
Production line: Downsview area of Toronto, Ontario, Canada.
Type aircraft: STOL utility transport.
First flight: August 16, 1947.
Produced: 1947 – 1967

With its all-metal construction, high-lift wing, and flap configuration, the DHC-2 Beaver was a robust aircraft with excellent short take-off-and-landing capability even with heavy loads.  It features a high-lift wing with its entire trailing edge hinged, hydraulically operated flaps and slotted ailerons. These special features permit the aircraft to take off and land in extremely short distances.

Another outstanding advantage of the Beaver is its ability to operate equally well on wheels, skis, floats or as an amphibian. Military operators including the US Army bought the Beaver for utility work and several went to war in Vietnam.
