The Anderson Greenwood AG-14 is a two-seat utility aircraft developed in the United States shortly after World War II. It is an all-metal, shoulder-wing monoplane of pod-and-boom configuration, equipped with a pusher propeller, side-by-side seating and fixed tricycle undercarriage. [1]
Anderson Greenwood's sole aircraft design was actually a collaborative effort of three engineers: Ben Anderson, Marvin Greenwood & Lomis Slaughter Jr. The name of the last member of the design team was not included in the product name as it was thought it would not boost sales. [1]
The prototype first flew in October 1947, but plans to mass-produce the aircraft were interrupted by the Korean War. Eventually, only five more examples were built before Anderson Greenwood abandoned the project in favour of producing aircraft components for other manufacturers.
The aircraft's design placed the wing behind the cabin and allowed easy entry via automobile-like doors on each side of the cabin. The propeller is well protected and provides safety on the ground in comparison to tractor configuration aircraft. The airfoil employed is a NACA 4418 giving high lift and a stable stall characteristics. The flaps are two-position and mechanically operated by a flap handle on the cabin floor between the seats. The engine starter is foot-actuated and the nose-wheel steering is connected to the control wheel. [1] [2]
Wind tunnel testing determined that a shoulder wing was ideal for minimal wing-body airflow separation that is intrinsic to a pusher configuration. The aspect ratio of 9.6:1 was high for aircraft at the time it was designed. The wing has 7 degrees of dihedral for directional stability. A four inch propeller shaft extension allows the engine to be mounted closer to the aircraft's center of gravity. The nose gear steers through the control yoke and not the rudder pedals. [3]
The AG-14 has very good visibility and one reviewer termed it "amazing". [2]
The aircraft was certified on 20 September 1950 in the normal category. The certification includes a prohibition on aerobatics and spins. One reviewer termed it as "positively spin resistant." [2] [4]
Serial numbers 1, 2 and 3 were produced in 1950, while 4 and 5 were built in 1953. [5] The five pre-production prototypes were the only examples built. The retail price of the aircraft was set at $4,200 - $4,500. [3]
In 1969 one AG-14 aircraft was acquired by Cessna Aircraft Company and taken to Wichita, Kansas for evaluation. Cessna designed and constructed a single prototype aircraft of similar configuration, the Cessna XMC, equipped with a Continental O-200 engine of 100 hp (75 kW), with the goal of a possible Cessna 150 replacement. The Cessna evaluation program ran through 1971 and 1972. While performance was similar to a C-150, the aircraft suffered from high cabin noise levels as well as cooling problems, while not providing any performance advantages over the Cessna 150. [6]
An AG-14 was also used as the basis of the XAZ-1 Marvelette test bed aircraft built by the Mississippi State University in the 1960s. [7]
In 1986 the Anderson Greenwood Company donated an AG-14, serial number 3, registered as N314AG to the Experimental Aircraft Association Aviation Foundation. [8] By the end of August 2008 it was no longer registered to the foundation.
In May 2009 the five production aircraft were still on the US registry listed as Anderson Greenwood AND-51-A. [5] By August 2018 only two remained registered in the US. [9]

General characteristics
Performance
The Cessna 208 Caravan is a utility aircraft produced by Cessna. The project was commenced on November 20, 1981, and the prototype first flew on December 9, 1982. The production model was certified by the FAA in October 1984 and its Cargomaster freighter variant was developed for FedEx. The 4 ft (1.2 m) longer 208B Super Cargomaster first flew in 1986 and was developed into the passenger 208B Grand Caravan.
The Cessna Skymaster is an American twin-engine civil utility aircraft built in a push-pull configuration. Its engines are mounted in the nose and rear of its pod-style fuselage. Twin booms extend aft of the wings to the vertical stabilizers, with the rear engine between them. The horizontal stabilizer is aft of the pusher propeller, mounted between and connecting the two booms. The combined tractor and pusher engines produce centerline thrust and a unique sound. The Cessna O-2 Skymaster is a military version of the Cessna 337 Super Skymaster.
The Curtiss-Wright AT-9 Jeep was a twin-engined advanced trainer aircraft used by the United States during World War II to bridge the gap between single-engined trainers and twin-engined combat aircraft. The AT-9 had a low-wing cantilever monoplane configuration, retractable landing gear and was powered by two Lycoming R-680-9 radial engines.
The Cessna 340 is a twin piston engine pressurized business aircraft that was manufactured by Cessna.
The Piaggio P.136 was an Italian twin-engine amphibian flying boat designed and manufactured by aircraft company Piaggio Aero. It is furnished with an all-metal hull, pusher propellers, a gull wing, and retractable landing gear.
The Goodyear GA-2 Duck was a 1940s American three-seat light amphibious aircraft built by the Goodyear Aircraft Corporation. The design team included David Thurston, who later developed several other light seaplanes including the Colonial Skimmer, Lake Buccaneer, Thurston Teal and Seafire. Only 19 aircraft were built, and these were used only for testing and as demonstrators.
The Fletcher FL-23 was an American two-seat liaison or observation aircraft designed and built by the California-based Fletcher Aviation Corporation. It was entered into a competition and lost against the Cessna 305A as a liaison or observation aircraft for the United States Army.
The SIAI-Marchetti SM.1019 is an Italian STOL liaison monoplane built by SIAI-Marchetti for the Italian Army, and based on the Cessna O-1 Bird Dog.
The PZL M-17 "Duduś Kudłacz" was a Polish twin-boom pusher general aviation and trainer aircraft of 1977, which remained a prototype.
The Nord 3400 Norbarbe was a French two-seat observation and casualty-evacuation aircraft built by Nord Aviation for the French Army Light Aviation.
The SECAN SUC-10 Courlis was a French high-wing touring monoplane designed and built by Société d'Etudes et de Construction Aéronavales (SECAN), a branch of the automobile company Société des Usines Chaussons. The aircraft had problems with the engine installation and only 144 were built, some without engines and were scrapped.
The Cessna XMC was a prototype technology demonstrator designed to show advanced aerodynamics and materials. The marketing name of XMC stood for "Experimental Magic Carpet" with the single test aircraft designated Cessna 1014 and later 1034 in company documentation.
The Mississippi XAZ-1 Marvelette was an American research aircraft of the 1960s. A converted Anderson Greenwood AG-14 light single-engined pusher aircraft, it provided the test-bed, or test platform, on which to test the boundary layer control system and ducted propeller installation of the planned XV-11 Marvel STOL research aircraft. One aircraft was converted to XAZ-1 configuration; although underpowered, it provided valuable test data over a year-long flight program. Following the conclusion of test flying, the aircraft was used for ground testing before being scrapped.
The Custer CCW-5 was a twin-engined, 5-seat aircraft of pusher configuration, which used a channel wing claimed to enable low speed flight and short take-offs. Two CCW-5s flew, eleven years apart, but the type never entered production.
The Grinvalds Orion is one of the earliest (1981) composite kit- and homebuilt aircraft. A 2/4 seater with a single pusher engine, it was built in France and the United States in small numbers with several variations.
The Bagalini Bagaliante is an Italian high-wing, strut-braced, single-seat, pusher configuration, conventional landing gear motor glider that was designed by Marino Bagalini and made available as plans for amateur construction.
The Partenair Mystere is a Canadian two-seat, pusher configuration monoplane that was designed by Partenair Design of Saint-Jean-sur-Richelieu, Quebec and intended for amateur construction from kits.
The Trident TR-1 Trigull is a Canadian amphibious aircraft that was developed by Trident Aircraft of Burnaby, British Columbia and later Sidney, British Columbia. The aircraft was intended to be supplied as a complete ready-to-fly certified aircraft. The company encountered financial difficulties and only three prototypes were ever built.
