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. Serial production started in 1966, and about 300 examples were built by the time production ended in 1972. The An-14 failed to replace the more successful An-2 biplane, which was manufactured until 1990,. The An-14's successor, the An-28 with turboprop engines, is still manufactured at PZL Mielec factories in Poland, under the names PZL M28 Skytruck and PZL M28B Bryza.

The Ling-Temco-Vought (LTV) XC-142 is a tri-service tiltwing experimental aircraft designed to investigate the operational suitability of vertical/short takeoff and landing (V/STOL) transports. An XC-142A first flew conventionally on 29 September 1964, and on 11 January 1965, it completed its first transitional flight by taking off vertically, changing to forward flight, and finally landing vertically. Its service sponsors pulled out of the program one by one, and it eventually ended due to a lack of interest after demonstrating its capabilities successfully.
The Saunders ST-27 was a regional aircraft built in the 1970s by the Canadian Saunders Aircraft Company based at Gimli, Manitoba. The aircraft was designed as a conversion of the earlier de Havilland Heron. The conversion program was extensive and featured two Pratt & Whitney Canada PT6 turboprops and a stretched fuselage. Despite its promise as a regional airliner, the project collapsed when Manitoba government funding was withdrawn in 1976.
The AIDC T-CH-1 Chung Hsing was a turboprop-powered military trainer aircraft produced in Taiwan.
The Anahuac Tauro is a Mexican agricultural aircraft built in small numbers in the late 1960s and 1970s. The first prototype flew on 3 December 1968, with Mexican Type certification following on 8 August 1969. It was a low-wing braced monoplane of conventional configuration with fixed tailwheel undercarriage. The wing was of constant chord and had spray bars installed along its trailing edge.
The Zlin Z-37 Čmelák, also known as LET Z-37 Čmelák is an agricultural aircraft which was manufactured in Czechoslovakia. It is powered by a Soviet-built Ivchenko reciprocating engine. The aircraft is used mainly as a cropduster.

The Bellanca T-250 Aries was a light airplane built in the United States in the early 1970s, which achieved only limited production. Designed by Marvin Greenwood while Anderson-Greenwood owned the Bellanca name, it was a conventional low-wing monoplane with retractable tricycle undercarriage and a high T-tail. Federal Aviation Administration type certification was obtained on 28 July 1976.
The Found Centennial 100 is a Canadian six-seat cabin monoplane produced by Found Brothers Aviation.

The DSK Airmotive DSK-1 Hawk was an unusual homebuilt aircraft designed in the United States in the early 1970s. While the design itself was utterly conventional - a single-seat low-wing cantilever monoplane with fixed tricycle undercarriage - its method of construction was not, since the DSK-1 Hawk used a surplus 200 US Gal military drop tank as its fuselage. Designer Richard Killingsworth sold over 250 sets of plans.
The SIAI-Marchetti SM.1019 is an Italian STOL liaison monoplane built by SIAI-Marchetti for the Italian Army. It is a turboprop-powered derivative of the Cessna O-1 Bird Dog.
The Wing D-1 Derringer is an American light twin-engined two-seat monoplane tourer designed by John Thorp and developed by the Hi-Shear Corporation and built by the Wing Aircraft Company.
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 Italair F.20 Pegaso was a twin-engine utility aircraft designed by Stelio Frati and built in Italy in 1971.
The NAC Fieldmaster was a British agricultural aircraft of the 1980s. A turboprop powered single-engined monoplane, it was built in small numbers and used both as a cropsprayer and a firefighting aircraft.
