The Commonwealth Skyranger, first produced as the Rearwin Skyranger, was the last design of Rearwin Aircraft before the company was purchased by a new owner and renamed Commonwealth Aircraft. [1] It was a side-by-side, two-seat, high-wing taildragger.
The Rearwin company had specialized in aircraft powered by small radial engines, such as their Sportster and Cloudster, and had even purchased the assets of LeBlond Engines to make small radial engines in-house in 1937. By 1940, however, it was clear Rearwin would need a design powered by a small horizontally opposed engine to remain competitive. Intended for sport pilots and flying businessmen, the "Rearwin Model 165" first flew on April 9, 1940. Originally named the "Ranger," Ranger Engines (who also sold several engines named "Ranger") protested, and Rearwin renamed the design "Skyranger." The overall design and construction methods allowed Rearwin to take orders for Skyrangers then deliver the aircraft within 10 weeks. [2] : 179–180
The Skyranger's development in 1940 [1] came shortly before the U.S. entered World War II. At that time, the U.S. government was purchasing almost any airplane in the two-seat, 50-90 horsepower class as training aircraft for the Civilian Pilot Training Program ("CPT Program" or "CPTP"), intended to develop tens of thousands of pilots for the possibility of U.S. involvement in the war. However, unlike its contemporaries heavily used in the CPTP such as the Piper Cub, Taylorcraft, Interstate Cadet, and Porterfield Collegiate, the Skyranger was rejected by the government for CPTP use as too challenging to fly. [1]
By 1942, Rearwin had produced only 82 Skyrangers (compared to hundreds or thousands of its competitors' planes) when World War II forced production to halt. [3] [4] [2] : 186
In 1945 Commonwealth Aircraft re-established production of the Skyranger. The first 12 had to be hand-built, as the original jigs and tooling were recycled or scrapped during World War II. [2] : 186 In 1946, production shifted to Valley Stream, New York. the Commonwealth Skyranger had minor modifications but was essentially the same as the pre-war aircraft. Commonwealth went bankrupt in 1946, and was dissolved in March of 1947, partly because the pre-war design failed to compete with new designs and cheap war surplus aircraft. [2] : 213
The Skyranger was a high-wing light plane seating two people side-by-side. It had a conventional landing gear with a tailwheel. It was constructed with a fabric-covered steel tube fuselage and wooden wing (with a semi-symmetrical airfoil cross-section. The Skyranger was powered by a variety of opposed engines made by Continental Motors and the Franklin Engine Company, [4] ranging from 65 to 90 horsepower. It sold for $1,795 to $2,400. [5] [2] : 180
The Skyranger handled differently from the other planes in its class (such as the Cub, Taylorcraft, Cadet, Collegiate, and Aeronca Chief), with a "heavy-airplane feel" (heavy controls, exceptional stability). With an unusually large vertical stabilizer for its size, the Skyranger was exceptionally susceptible to crosswinds during landing and taxiing. [4] [1] Unusually for the time and aircraft in its class, the Skyranger was also designed with slots in its outer wings to allow controllability at lower speeds. [2] : 181
Rearwin also offered a low-cost version of the Skyranger from 1940 to 1941. [2] : 180

The Piper PA-28 Cherokee is a family of two-seat or four-seat light aircraft built by Piper Aircraft and designed for flight training, air taxi and personal use. The PA-28 family of aircraft comprises all-metal, unpressurized, single-engined, piston-powered airplanes with low-mounted wings and tricycle landing gear. They have a single door on the right side, which is entered by stepping on the wing.
The Fairchild PT-19 is an American monoplane primary trainer aircraft that served with the United States Army Air Forces, RAF and RCAF during World War II. Designed by Fairchild Aircraft, it was a contemporary of the Kaydet biplane trainer, and was used by the USAAF during Primary Flying Training. As with other USAAF trainers of the period, the PT-19 had multiple designations based on the powerplant installed.
The Stinson L-13 was a US military utility aircraft first flown in 1945.
The Cessna 180 Skywagon is a four- or six-seat, fixed conventional gear general aviation airplane which was produced between 1953 and 1981. Though the design is no longer in production, many of these aircraft are still in use as personal aircraft and in utility roles such as bush flying.

Rearwin Airplanes was a series of US airplane-manufacturing businesses founded by Andrew ("Rae") Rearwin in 1928. Rae Rearwin was an American businessman who had developed several successful business ventures in the Salina, Kansas area in the early 20th century. Although he had no experience with aircraft manufacturing, he felt that he could succeed with his solid business acumen. With his two sons, Ken and Royce, he hired some engineers and built the Ken-Royce in a garage in Salina. The business moved to the Fairfax Airport in Kansas City, Kansas, and went through several variations before it was sold to Commonwealth Aircraft in 1942, which went bankrupt in 1946.
