Pitcairn PA-19

The Pitcairn PA-19 was a four-seat autogyro developed in the United States in the early 1930s.^[1] While most of Pitcairn's autogyro designs featured open cockpits in tandem, the PA-19 had a fully enclosed cabin.^[2][3] It also had wings that carried control surfaces.^[2] The rotor provided lift only, but could be tilted in flight to trim the aircraft.^[4] Four examples were built before the effects of the Great Depression forced Pitcairn to abandon autogyro production in 1934.^[2][4]
