About the DEHAVILLAND PROVOST
The de Havilland DHC-2 Mk. I, also known as the Beaver, and designated L-20A by the U.S. military, is a single-engine, high-wing, propeller-driven short takeoff and landing (STOL) aircraft. Developed by the Canadian company de Havilland Canada, the Beaver was introduced in 1947 and produced until 1967, with over 1,600 units built. It quickly became iconic for its ruggedness, reliability, and versatility, making it a preferred choice for bush flying, a niche that involves navigating remote and rugged terrains often accessible only by air.
The DHC-2 Beaver was motivated by the need for a robust aircraft capable of carrying substantial cargo loads into rugged, inaccessible areas such as those found in Canada and Alaska. Before its production, many remote operators relied on older, less capable aircraft that struggled with the demands of bush flying. Recognizing this, de Havilland Canada designed the Beaver to exceptionally high standards of durability and performance, thereby meeting the unique needs of Canadian bush pilots.
Key Features and Capabilities
One of the Beaver's standout features is its STOL capability, enabling it to take off and land on short, unprepared airstrips, which is crucial for operations in isolated areas. Its Pratt & Whitney R-985 Wasp Junior radial engine provided reliable and ample power, while its high wing design, large flaps, and robust undercarriage allowed for excellent handling and stability even under adverse conditions.
The aircraft was adapted for amphibious operations with the addition of floats, and some models were equipped with skis for snow landings, enhancing its versatility. The Beaver also found a significant role in military operations, with the U.S. Army and Air Force using it for reconnaissance, medical evacuation, and personnel transport under the designation L-20A.
Market Position and Use Cases
Today, the de Havilland DHC-2 Beaver remains a beloved aircraft among aviators and continues in service worldwide, often restored and maintained by enthusiasts who appreciate its historical significance and unmatched utility in rugged environments.
