Pitcairn Aircraft Company

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.

History

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.^[1]

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.^[2]

PCA-2

The first aircraft, a Pitcairn PA-1 Fleetwing was built at the Bryn Athyn field.^[3] In 1927, Pitcairn brought aboard a friend and designer from his apprenticeship days at Curtiss Aeroplane and Motor Company, Agnew E. Larson. Larson left the Thomas-Morse Aircraft company to join Pitcairn.^[1] 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 thirteen other companies.^[3] In 1928, Pitcairn purchased a Cierva C.8W and the American manufacturing rights from Juan de la Cierva for his autogiro designs^[4][5] for $300,000.^[6] 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.^{[citation needed]} As a part of the licensing agreement, Pitcairn used Cierva's copyrighted variant of the name autogiro (spelt 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 with one being demonstrated in the 1929 Cleveland Air Races. Following a fire in November 1929, The first PCA-1 was built and tested the same month.^[7] In June 1929,Clement Keys personally bought all the shares of Pitcairn Aviation (The airline and flying school) for 2.5 million dollars, and resold them two weeks later to North American Aviation, which renamed the company Eastern Air Transport, and finally Eastern Airlines.^[8] From this point on, Pitcairn focused on autogiros.

In 1931 the company was renamed to the Autogiro Company of America (ACA).^[7] 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 semi-hover for better camera shots. This PCA-2 was the ancestor of today's news helicopters.^[9] 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.^[10]

In 1932, autogyro inventor Cierva was greeted by U.S. President Herbert Hoover, who predicted in the future we would have large transport autogyros.^[11] 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.^[12]

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.^[6] As a member of the board of directors of the Cierva Autogiro Company, Pitcairn was shocked to learn shortly afterward that the company had also licensed technology in Europe to the German Focke Achgelis Company creating competition to the autogiro with a practical helicopter, the Focke-Wulf Fw 61.^[13]

In 1938, the company was renamed to the Pitcairn-Larson Autogiro company, and again in 1940 to the AGA Aviation Corporation.^[3]

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. Pitcairn reduced royalties for 19 in house patents and 145 licensed patents to subcontractors of the government during wartime. After 1946, other manufacturers continued to produce helicopters without paying royalties. The company was dissolved in 1948. Pitcairn continued to pursue litigation for use of the patents by other firms in 1951 that stretched into a 1977 Supreme Court Case awarding Pitcairn's estate^[13] 32 million dollars.^[6]

Military operations

•  United Kingdom
•  United States

The US Navy evaluated a PCA-2 in 1931, designated as Pitcairn OP on the aircraft carrier USS Langley, to become the first rotory wing craft to land on a ship at sea.^[14]

In 1940 6 Pitcairn PA-18 autogyros were converted to Pitcairn PA-39 models for convoy escorts for the Fleet Air Arm.^[15]

Survivors

Pitcairn's influence on early airmail service and rotary-wing flight have inspired several museums to display Pitcairn aircraft prominently.

• The EAA AirVenture Museum in Oshkosh, Wisconsin built a replica Pitcairn hangar on its Pioneer Airport filled with Pitcairn displays. Harold Pitcairn's son, Steve Pitcairn (1925–2008) remained active restoring Pitcairn aircraft, including a Pitcairn PA-5 Mailwing, A Pitcairn PCA-2 "Miss Champion", a PA-7S Sport Mailwing, and a Pitcairn PA-39. donated to the museum ^[16]

• The National Air and Space Museum in Washington D.C. has a Pitcairn PA-5 Mailwing on display in Eastern Air Transport US Mail No 19 markings.

• The The Henry Ford Museum in Dearborn, Michigan has a Pitcairn PCA-2 on display in the markings of Detroit News No 2.

• The Old Rhinebeck Aerodrome has a Pitcairn PA-6 Super mailwing in Eastern Air Transport US Mail (CAM No 77) markings, painted black and yellow in one of their static display hangars.

• The Virginia Aviation Museum has a Pitcairn PA-5 Mailwing in Eastern Air Transport US Mail (CAM No 27) markings, painted similarly to the Old Rhinebeck PA-6.

• A Pitcairn PA-8 Super Mailwing formerly owned by Steve McQueen is currently in private hands with The Woodlands Toy Store of Pennsylvania, having been fully restored in silver and green, but it has flown in a number of airshows in the Northeast, including at Geneseo, New York.

• A Pitcairn PA-8 Super Mailwing is on display at the Wings of Freedom Aviation Museum in Horsham, Pennsylvania.
