context_page_description: 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 Autogiro Company of America among other names, remained in business until 1948.
context_section_description: Harold Frederick Pitcairn, the youngest son of PPG Industries founder, John Pitcairn, Jr., founded Pitcairn Aircraft Company. The business started with the formation of Pitcairn Flying School and Passenger Service on 2 November 1924, which later became Eastern Airlines.
  In 1926, Pitcairn started Pitcairn Aircraft Company initially to build aircraft for his growing airmail service. He purchased a field in Horsham Township, Montgomery County, Pennsylvania and built Pitcairn Field no. 2.
  The first aircraft, a Pitcairn PA-1 Fleetwing, was built at the Bryn Athyn field. In 1927, Pitcairn brought aboard a friend and designer from his apprenticeship days at Curtiss Aeroplane and Motor Company, Agnew E. Larsen. Larsen left the Thomas-Morse Aircraft company to join Pitcairn. In June 1927, the state of the art Wright Whirlwind powered Pitcairn PA-5 Mailwing was introduced for airmail service.  The plane proved popular and was bought by 13 other companies. In 1928, Pitcairn purchased a Cierva C.8W and the American manufacturing rights from Juan de la Cierva for his autogiro designs for $300,000. 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 for $300,000. As a part of the licensing agreement, Pitcairn used Cierva's copyrighted variant of the name Autogiro (capitalized and spelled with an i) as opposed to the currently more common spelling of autogyro which was initially used to bypass his copyright.
  In 1929, three prototypes were built, and one was demonstrated in the 1929 Cleveland Air Races. Following a fire in November 1929, The first PCA-1 was built and tested the same month. In June 1929, Clement Keys personally bought all the shares of Pitcairn Aviation (the airline and flying school) for $2.5 million, and resold them two weeks later to North American Aviation, which renamed the company Eastern Air Transport, and finally Eastern Airlines. From this point on, Pitcairn focused on autogiros.
  In 1931, the company was renamed to the Autogiro Company of America (ACA). In 1931, The Detroit News made history when they bought the first Pitcairn PCA-2 for use as a news aircraft due to it ability to fly well at low altitude and speed, land and take off from restricted spaces, and semihover for better camera shots.  This PCA-2 was the ancestor of today's news helicopters.  Also in 1931, pilot James G. Ray landed an autogiro on the south lawn of the White House. Harold F. Pitcairn, the pilot, and three other company members of the Pitcairn-Cierva Autogiro Company were present to receive the Collier Trophy for their development of the autogyro.
  In 1932, autogyro inventor Cierva was greeted by U.S. President Herbert Hoover, who predicted in the future we would have large transport autogyros. Amelia Earhart borrowed a company Pitcairn PCA-2 model. She arranged for the National Aeronautics Association to monitor the flight. Members of the New York press and Movietone News were invited to watch. On her second flight, she remained airborne for about three hours and set a woman's autogiro altitude record of 18,415 feet. Later, she toured the country for Beech-Nut Packing Company in a bright green autogiro. On the return trip, she crash landed in Abilene, Texas, earning her a reprimand from the United States Department of Commerce. A second crash at the Michigan state fair, caused an unintended injury of her husband's ankle as he ran to the scene.
  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.
  On December 9, 1936, Juan de la Cierva died in a crash of a KLM DC-2. The Cierva Autogiro Company, Ltd., largely financed by the Scottish marine engineering firm of G & J Weir, Ltd., was then engaged in development of the "autodynamic" rotor, unworkable features of wh
