The Spartan C5 was a passenger and utility aircraft produced in small numbers in the United States in the early 1930s.[1][2][3] It was a further, ultimately unsuccessful, attempt to market the Spartan C4, from which it was developed.[2] Like its predecessor, the C5 was a high-wing, strut-braced monoplane with a fully enclosed cabin.[1] Seating was increased to five places in place of the four seats of the C4.[4] The C5 also incorporated a number of aerodynamic refinements, including a closely cowled engine and spatted mainwheels. The fuselage was constructed of welded steel tube and the wings from wood, and the whole aircraft covered in fabric.[5] The empennage was also mostly constructed from wood, with metal ribs used in the fin and the whole assembly also covered in fabric.[5]
Spartan was unable to sell the aircraft in any quantity, and eventually, built only four examples, including the prototype.[1]
