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]

  • PA-20 - improved version with Kinner R-5 engine[2]
  • PA-24 - version with twin tails and Kinner R-5 engine, modified from existing PAA-1s and PA-20s[2]
