The Pitcairn PAA-1 was an autogyro developed in the United States in the early 1930s.^[1] Of similar configuration to Pitcairn's earlier machines, the PAA-1 had an airplane-like fuselage with two open cockpits in tandem and a tractor-mounted engine in the nose.^[2] It was also equipped with small wings, which carried control surfaces, rather than using the rotor for flight control.^[2] It was a smaller and lighter machine than its predecessors and was designed specifically with private pilots in mind.^[1][2]
