The Antonov An-14 Pchelka or Pchyolka, Bdzhilka is a Soviet utility aircraft which was first flown on 15 March 1958. It was a twin-engined light STOL utility transport, with two 300 hp Ivchenko AI-14RF radial piston engines.

The Vulcanair SF.600 Canguro was a feederliner developed in Italy in the late 1970s. Despite a number of attempts to put the aircraft into series production, only a small number were ever built. The Canguro was a high-wing cantilever monoplane of conventional configuration with a fuselage of rectangular cross-section and a high-set tail. The tricycle undercarriage was not retractable, and its main units were carried on sponsons on the fuselage sides. SIAI Marchetti provided funding towards the construction of the prototype, and constructed this aircraft at the former Aviamilano plant. After flight testing proved positive, the type was put on sale, but failed to attract buyers in any number, even when the original piston engines were exchanged for turboprops and retractable undercarriage was offered as an option.
The Grob Strato 2C was a German experimental high altitude research aircraft. Powered by two turbocharged piston engines and featuring an extremely long span wing of composite construction, one aircraft was built in the 1990s, but was abandoned despite setting a world altitude record for piston-engined aircraft on its last flight.
