U-6A (L-20) 'Beaver' Utility (Canada)

The de Havilland Canada DHC-2 Beaver is a single-engined high-wing propeller-driven short takeoff and landing aircraft developed and manufactured by de Havilland Canada. It has been primarily operated as a bush plane and has been used for a wide variety of utility roles, such as cargo and passenger hauling, aerial application, and civil aviation duties.

Shortly after the end of the Second World War, de Havilland Canada decided to orient itself towards civilian operators. Based on feedback from pilots, the company decided that the envisioned aircraft should have excellent STOL performance, all-metal construction, and accommodate many features sought by the operators of bush planes. On 16 August 1947, the maiden flight of the aircraft, which had received the designation DHC-2 Beaver, took place.
