The Pitcairn Aircraft Company was an American aircraft manufacturer of light utility aircraft. An early proponent of the autogyro, the company, later known as the Autogyro Company of America among other names, would remain in business until 1948.In 1926, Pitcairn started Pitcairn Aircraft Company initially to build aircraft for his growing airmail service.In 1929, Pitcairn formed a separate patent holding company to build autogiros, the Pitcairn-Cierva Autogiro Company, which was later renamed the Autogiro Company of America. Kellett autogyros competed with, and eventually licensed production rights from Pitcairn-Cierva Autogiro Company.In 1931 the company was renamed to the Autogiro Company of America (ACA).In 1933, the parent company and conventional aircraft manufacturing arm, Pitcairn Aircraft Company merged with the autogiro arm, following the end of Mailwing production, and contract air-mail flights.In 1938, the company was renamed to the Pitcairn-Larsen Autogiro Company.In 1940 the company was renamed to the AGA Aviation Corporation.In 1942, Pitcairn sold his airfield and facilities to the United States military for $480,000, forming the Naval Air Station Joint Reserve Base Willow Grove. AGA Aviation was now renamed to G and A Aviation, and became part of Goodyear Tire and Rubber. The last designs of the AGA/G & A lineage appeared under the name Firestone.Biplane aircraftPA-1 FLEETWING (1925)PA-2 SESQUI-WING (FLEET ARROW) (1925)PA-3 OROWING (Type 2-20, 1925)PA-3A OROWING II PA-4 FLEETWING II (FLEETWING DELUXE) (Type 2-21, 1927)PA-5 MAILWING (ATC-18, 1927)PA-5 SPORT MAILWING (1928)PA-5 MAILWING SPORT SPECIAL (1928)PA-6 SPORT MAILWING (ATC-92, previously under Type 2-22, 1928)PA-6 SUPER MAILWING same as the PA-6S?
