The Buhl Aircraft Company was a US aircraft manufacturer founded in Detroit in 1925 which remained in operation until 1933. Buhl designed and manufactured the Buhl-Verville CA-3 Airster, the first aircraft to receive a US civil aviation type Certificate in March 1927. Several utility and sport aircraft models were developed from 1925 to 1931, both fixed wings and rotary wing aircraft. Their greatest successes were with the Airsedan and Bull Pup, with approximately 185 aircraft of all types built from 1925 to 1932.
The first aircraft to receive an Approved Type Certificate in the United States was the Buhl CA-3 Airster biplane which received Certificate #1 in March 1927. This was a commercial three seat open cockpit biplane suitable for carrying a couple of passengers, training student pilots and carrying light cargo. Other jobs such as crop dusting and aerial photography would be added later. Alfred Verville was the chief designer from the company's founding in 1925 until 1927, during the period when the CA-3 Airster was developed and certified. 20 would ultimately be built.[2]
Etienne Dormoy replaced him, and was responsible for developing the Airsedan sesquiplane family, as well as the CA-1 Airster and Bull Pup monoplanes. Roughly 85 Airsedans in two basic designs (the CA-5, and much more refined CA-3, 6 and 8) were built which won a number of speed and endurance records and placed in the top in the Ford National Reliability Air Tour, the National Air Races. The Airsedan "Spokane Sun-God" was the first aircraft to make a non-stop US transcontinental round-trip flight on 15 August 1929. Sales would be hindered by the deepening Great Depression although over 100 of the tiny single-seat Bull Pup monoplanes were manufactured between 1930 and 1932.[3]
Dormoy also designed the Buhl A-1autogyro in 1930, optimized for aerial photography, with a pusher engine located behind the pilot and room for a camera operator up front.[4]
Only one of these was built.
