The Cunningham-Hall Model PT-6 was an American six-seat cabin biplane aircraft of the late 1920s and was the first design of the Cunningham-Hall Aircraft Corporation of Rochester, New York.
The Buhl-Verville CA-3 Airster, was a utility aircraft built in the United States in 1926, notable as the first aircraft to receive a type certificate in the US, issued by the Aeronautics Branch of the Department of Commerce on March 29, 1927. It was a conventional single-bay biplane with equal-span unstaggered wings and accommodation for the pilot and passengers in tandem open cockpits. Marketed for a variety of roles including crop-dusting, aerial photography, and freight carriage, only a handful were built, some with water-cooled engines as the CW-3, and others with air-cooled engines as the CA-3. One CA-3 placed second in the 1926 Ford National Reliability Air Tour.
The Buhl AirSedan was a family of American civil cabin sesquiplane aircraft developed and manufactured by the Buhl Aircraft Company in the late 1920s. One example completed the first transcontinental non-stop roundtrip flight, made in 1929 by the CA-6 Spokane Sun-God, and the first Pope to have flown did so in a Buhl Airsedan.
The Curtiss Fledgling, known internally to Curtiss as the Model 48 and Model 51 was a trainer aircraft developed for the United States Navy in the late 1920s and known in that service as the N2C.
The Curtiss-Wright CW-12 Sport Trainer and CW-16 Light Sport were high-performance training aircraft designed by Herbert Rawdon and Ted Wells and built in the United States in the early 1930s.
The Travel Air 2000/3000/4000 (originally, the Model A, Model B and Model BH were open-cockpit biplane aircraft produced in the United States in the late 1920s by the Travel Air Manufacturing Company. During the period from 1924–1929, Travel Air produced more aircraft than any other American manufacturer, including over 1,000 biplanes. While an exact number is almost impossible to ascertain due to the number of conversions and rebuilds, some estimates for Travel Air as a whole range from 1,200 to nearly 2,000 aircraft.
The Curtiss-Wright CW-19 was a civil utility aircraft designed in the United States in the mid-1930s and built in small quantities in a number of variants including the CW-23 military trainer prototype.
The Curtiss Model 55 Kingbird was an airliner built in small numbers in the United States in the early 1930s. It was a twin-engine aircraft with a fuselage derived from the single-engine Curtiss Thrush. The Kingbird had two engine nacelles mounted on the struts on either side of the fuselage that braced the wing and the outrigger undercarriage. A distinctive design feature was the aircraft's blunt nose, located behind the propeller arcs. This allowed the engines to be mounted closer to each other and to the aircraft's centerline, therefore minimising asymmetrical thrust in case of an engine failure. For the same reason, the Thrush's single tailfin was replaced by twin tails on the Kingbird, and the main production model, the D-2 fitted a second horizontal stabilizer and elevator between these fins.
The Bullet Monoplane or Alexander Eaglerock Bullet was a low wing cabin monoplane that was a departure from traditional biplane aircraft of the era.
The Wright R-540 Whirlwind was a series of five-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright. These engines had a displacement of 540 in³ (8.85 L) and power ratings of around 165-175 hp (123-130 kW). They were the smallest members of the Wright Whirlwind engine family.
The Lincoln-Page PT was an American open-cockpit two-seat single-bay biplane trainer aircraft produced from 1929 to 1931.
The Stinson Detroiter was a six-seat cabin airliner for passengers or freight designed and built by the Stinson Aircraft Syndicate, later the Stinson Aircraft Corporation. Two distinct designs used the Detroiter name, a biplane and a monoplane.
The Stearman 4 is an American commercial biplane that was manufactured in the 1920s by Stearman Aircraft. They were marketed at the time as fast and luxurious executive transports and mail planes for about US$16,000.
The Spartan C3 is an American three-seat open-cockpit utility biplane from the late 1920s.
The Emsco B-4 Cirrus was a mid-wing, two-seat trainer built in the US in the late 1920s. Six were built and three variants with more powerful engines flown.
The Command-Aire 3C3 and similar 4C3 and 5C3 are American three-seat open cockpit utility, training and touring biplanes developed by Command-Aire in the late 1920s and early 1930s.
The Curtiss-Wright CW-14, named variously Travel Air, Sportsman, Speedwing and Osprey is an American 3-seat open cockpit single-bay biplane from the 1930s that was developed by Travel Air as a replacement for the highly successful Travel Air 4000. As a result of the Great Depression, which also limited sales, Travel Air merged into the Curtiss-Wright group of companies before production could start, so all examples were built by Curtiss-Wright. Its main claim to fame would be as the most numerous aircraft used in the Chaco war, where it formed the backbone of the Bolivian Air Force.
The Butler Blackhawk and the Skyway from which it was developed were American three-seat open-cockpit single engine biplanes of the late 1920s that were built in small numbers immediately prior to having their intended production run interrupted by the onset of the Great Depression.
The Travel Air Model 10 was a 4-seat single-engined light aircraft of the late 1920s. Twelve aircraft were built before production ended.
