The de Havilland Canada DHC-2 Beaver is a single-engined high-wing propeller-driven short takeoff and landing (STOL) 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 (crop dusting and aerial topdressing), and civil aviation duties. Shortly after the end of the Second World War, de Havilland Canada made the decision to orient itself towards civilian operators. Based upon 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. In April 1948, the first production aircraft was delivered to the Ontario Department of Lands and Forests.

General Characteristics and Role
The de Havilland Canada DHC-2 Beaver is a single-engined, high-wing, propeller-driven Short Take-Off and Landing (STOL) aircraft developed and built in Canada. Designed specifically for operations in rugged, remote areas with demanding flight conditions—often referred to as the bush plane role—the Beaver is renowned for its durability, power, and phenomenal ability to operate from minimal airstrips, water (as a seaplane), or snow (with skis). The U-6A designation was the version used by the US Army and US Air Force, which bought hundreds of Beavers for utility, liaison, and light cargo duties during the 1950s and 60s. The Beaver is considered one of the most successful utility aircraft ever built and is an iconic part of aviation history in Canada and Alaska.
