The Pitcairn PCA-2 was an autogyro developed in the United States in the early 1930s,[1] Harold F. Pitcairn's first autogyro design to sell in quantity. It had a conventional design for its day – an airplane-like fuselage with two open cockpits in tandem, and an engine mounted tractor-fashion in the nose.[2] The lift by the four-blade main rotor was augmented by stubby, low-set monoplane wings that also carried the control surfaces.[2] The wingtips featured considerable dihedral to act as winglets for added stability.[2]

The PCA-2 was the first rotary-wing aircraft to achieve type certification in the United States[3] and was used in a number of high-profile activities including a landing on the White House lawn[4][5] and the first flight across the United States in a rotorcraft. This latter feat was attempted by Amelia Earhart, flying for the Beech-Nut food company, but was actually accomplished by John M. Miller who completed his flight nine days before Earhart on 28 May 1931, in his PCA-2 named Missing Link.[6] Learning of Miller's achievement upon her arrival in California, Earhart set out to turn her flight into a round-trip record by flying east again, but abandoned the attempt after three crashes.[6] Earhart set an altitude record in a PCA-2 on 8 April 1931 with a height of 18,415 ft (5,615 m).[2][3][4] This record was broken in another PCA-2 by Lewis Yancey who flew to 21,500 ft (6,600 m) on 25 September 1932.[3][7]

PCA-2 operated by the Detroit News, displayed at the Henry Ford Museum in Dearborn, MI.

In 1931, The Detroit News made history when it bought a PCA-2 for use as a news aircraft due to its ability to fly well at low altitude, land and take off from restricted spaces, and semi-hover for better camera shots. In May 1933, Scripps donated the autogyro to the Henry Ford Museum in Dearborn, Michigan.[8]

The Champion spark plug company operated a PCA-2 as a promotional machine in 1931 and 32 as Miss Champion.[4] It was flown over 6,500 miles in the 1931 Ford National Reliability Air Tour. This machine was restored to flying condition in 1982 by Steve Pitcairn, Harold's son.[4] In 2005, he donated it to the EAA AirVenture Museum.[4] Other PCA-2s are preserved at The Henry Ford[4][9] and the Canada Aviation Museum.[10]
