Other suggestions that were seemingly mundane, but important in the bush plane world, included the installation of full-sized doors on both sides of the aircraft, which meant that it could be readily loaded no matter which side of a dock it tied up on; the doors were also made wide enough to allow for a 44

; it was flown by Second World War flying ace Russell Bannock. After completing its flight test programme, the prototype received several adjustments and improvements in order for it to serve as a flying demonstration model ready for the sales circuit. The prototype was ultimately sold to Central British Columbia Airways, as a routine day-to-day working air-taxi airplane and continued to fly as such with various air-taxi operators until 1980, after which it was retired and preserved. In April 1948, the first production aircraft was delivered to the Ontario Department of Lands and Forests, who had been a design partner.


Production

Initial sales were slow, perhaps two or three a month but as the plane was demonstrated sales started to improve. A key event in the Beaver's history occurred the next year when the US Army commenced its search for a new utility aircraft to replace their fleet of Cessnas. The competition quickly boiled down to the Beaver and the

. The Beaver won and during the Korean War, the US Army ordered 970, more than half of the overall production run for the type. Soon, the Beaver grew to become an export success as orders for the type increased from customers around the world. Individual military services of more than 30 different nations would ultimately be included amongst its operators. In later life, as the type was gradually phased out of military service, many examples underwent conversion work so that they could continue to be operated as civilian aircraft instead. During the 1960s, de Havilland developed an improved model of the Beaver, the Mk.III Turbo Beaver, which was equipped with a

engine. A total of sixty aircraft were built during the late 1960s. In 1967, when production of the type finally ceased, a total of 1,657 DHC-2 Beavers had been constructed. The Beaver was designed for flight in rugged and remote areas of the world. Its STOL capability made it ideal for areas normally only accessible by canoe or foot. Because the aircraft often flies to remote locations and in cold climates, its oil reservoir filler is located in the cockpit and oil can be filled in flight. A series of upgrades to the basic design were incorporated. One major customer introduced the use of flat steps replacing the earlier tubes, a feature now almost universal. In 1987, the Canadian ''Engineering Centennial Board'' named the DHC-2 as one of the top ten Canadian engineering achievements of the 20th century.

Viking has stated its interest in the potential restart of production of the Beaver, and commented that, dependent upon market demand, the firm may offer two separate models of the Beaver, one intended to be close to the design of the original batch, and another incorporating various improvements such as new avionics, engines, and doors, as well as likely being stretched to provide increased internal space. Stolairus Aviation of Kelowna, British Columbia has developed several modifications for the DHC-2 including a STOL Kit which modifies the wing with a contoured leading edge, flap-gap seals, wing fences and drooped wingtips for increased performance. Stolairus has also developed a Wing Angle Kit which changes the incidence of the wing. Advanced Wing Technologies of Vancouver, British Columbia has developed and certified a new wing for the DHC-2. The FAA Supplemental Type Certificate also raises the aircraft's gross weight to . So far, at least two Beavers have been modified in such a manner. In September 2017 the Transportation Safety Board of Canada recommended stall warning devices be mandated for commercial Beaver operators. In March 2019, Harbour Air announced plans to convert a DHC-2 Beaver to an electric aircraft and eventually to convert its entire fleet. The first test flight of the aircraft took place in Vancouver in December 2019.

The Beaver was designed to operate in all seasons and the majority of weather conditions; a large proportion were also equipped with Float (nautical), floats for buoyancy in water; it reportedly possesses favourable performance characteristics for a floatplane.

. In order to provide the necessary weight balance for optimal loading flexibility, the engine was mounted as far rearwards as possible, resulting in elements intruding into the cockpit space, such as the oil tank being positioned within the center console between the pilot and copilot's feet and the main fuel tank within the forward belly of the aircraft, which also improves accessibility for replenishment. Many Beavers have had wingtip tanks also installed; careful fuel management between the various fuel tanks is required throughout flights in order to maintain the aircraft's center of gravity. The remanufactured DHC-2T Turbo Beaver is equipped with a PT6A-34 turboprop engine. The Beaver is functionally shaped in order to accommodate a useful and sizable payload, typically close to , even when equipped with floats. While the front doors are narrow, the aft doors are wider, having been designed to facilitate the loading of 55-gallon barrels, either upright or on their sides. The Beaver is considered a 'working' aircraft, which was designed for vigorous use. In addition to cargo, passengers can also be carried; when appropriately fitted out, the Beaver Mk.I can accommodate up to seven passengers while the more spacious Beaver Mk.III can hold a maximum of 11. Various alterations have been approved, including alternative seating arrangements, enlarged cargo doors, larger windows and smaller Battery (electricity), batteries have been approved for use. During takeoff, both the ailerons and Flap (aeronautics), flaps are lowered, which is a relatively uncommon design approach but results in substantially elevated STOL performance. The flaps can be deployed to an extreme range, extending out at full to a 58-degree position; the flight manual notes that the full setting is recommended only for performing emergency landings. In the skies, the Beaver is relatively easy to handle, having been described as possessing light and comfortable controls.

Operational history

Despite the fact that production ceased in 1967, hundreds of Beavers are still flying—many of them heavily modified to adapt to changes in technology and needs. Kenmore Air of Kenmore, Washington, provides Beaver and Otter airframes with ''zero-hour'' Fatigue (material), fatigue-life ratings, and owns dozens of supplemental type certificates (STCs) for aircraft modifications. These modifications are so well known and desirable in the aviation community, rebuilt Beavers are often called "Kenmore Beavers" or listed as having "Kenmore mods" installed."Beaver Rebuild Program."

of the Beaver is long out of production, so repair parts are getting harder to find. Some aircraft conversion stations have addressed this problem by replacing the piston engine with a Turbopropeller, turboprop engine such as the Pratt & Whitney Canada PT-6, PT6. The added power and lighter installed weight, together with greater availability of kerosene fuel instead of high-octane aviation gasoline, make this a desirable modification, but at a high cost. The Beaver was deployed by the British Army Air Corps (United Kingdom), Army Air Corps during the Troubles, at least until 1979, for photo-reconnaissance missions. One of them was hit seven times by machine gun fire in South County Armagh, near the Republic of Ireland – United Kingdom border, border with the Republic of Ireland in November 1979, while taking photos of an Provisional Irish Republican Army, IRA checkpoint. The border crossing where the action took place became known to the British Army as "Beaver Junction". Operators of significant numbers of piston-Beavers in early 2008 include Air Saguenay and Harbour Air in Canada and Kenmore Air in the US.

The Civil Air Patrol operated many of the DHC-2 Beaver, where it was commonly used for conducting search and rescue missions. For some decades, the United States Navy has operated a pair of DHC-2s at the United States Naval Test Pilot School, where they are used to instruct students in the evaluation of lateral-directional flying qualities and for the towing of Glider (sailplane), gliders. In recent years, growing numbers of the type have been used within the leisure industry, being used for pleasure flight and as lifting platforms for Parachuting, skydiving and aerial film activities. The DHC-2 Beaver has been used by skydiving operators due to its good climb rate. When fitted with a roller door that can be opened in flight, it can quickly ferry eight skydivers to .
