Hispano Aviacon HA-42 / HA-43


First flying in 1947, the Hispano HS-42 and its derivative, the HA-43, were advanced military trainer aircraft produced in Spain. The basic design was that of a conventional, low-wing, cantilever monoplane with seating for the pilot and instructor in tandem.
The HS-42 had fixed, tailwheel undercarriage with spatted mainwheels, while the HA-43 had retractable main units. Produced on the assembly line that had been used to build Fokker D.XXI fighters, the HS-42 shared some components with this aircraft.
