The Pitcairn PA-18 was an autogyro produced in the United States in the early 1930s.[1]

History

[edit]

In 1931, Pitcairn had produced a lightweight autogyro suitable for the private pilots as the PAA-1.[2] Experience with this and with other light, low-powered machines convinced Pitcairn that while the concept was good, they presented significant handling problems to inexperienced pilots.[2] The PA-18 was designed as a machine for the same market, but with a more powerful engine and structural strengthening.[2] The availability of more power contributed greatly to the aircraft's responsiveness at low speeds.[2]

According to Frank Kingston Smith Sr. wrote, "Pitcairn's assessment of the market had been correct: within a year and a half more than nineteen PA-18s were produced and sold, vindicating his decision to proceed with the basic machine while experimenting with the direct-control system."[3]

In 2008, a PA-18 was restored to flying condition by Jack and Kate Tiffany of New Carlisle, Ohio.[4] At the same time, a second PA-18 was under restoration by the Posey Brothers firm at the Trenton-Robbinsville Airport.[5] Most other PA-18s were purchased by the United States government in 1940 and sold on to the United Kingdom.[4] They never arrived, however, since the ship carrying them was sunk by a German submarine.[4]
