The Bartlett LC-13A Zephyr 150 was a United States light civil aircraft built in the 1940s. It was a mid-wing braced monoplane of conventional design with side-by-side seating for two and fixed, tailwheel undercarriage. It was originally marketed as the Babcock LC-13 by its original manufacturer, then as the Taubman LC-13 when the Babcock Airplane Corporation was acquired by Taubman Aircraft. The rights were finally acquired by Bartlett Aircraft in 1941, but plans to mass-produce it were halted by the outbreak of World War II. There was a brief attempt to revive the design at the end of the war, but nothing came of this.
The Fokker F.25 Promotor, first flown in 1946, was a single-engined, twin-boomed, four-passenger monoplane with a pusher engine mounted at the rear of a central nacelle. It was of wooden construction and has fitted with a retractable nosewheel undercarriage. One feature of the design was that instead of a 2 + 2 seating, the pilot sat in front to the left, and all three passengers were on a bench seat to the rear of him. Alternatively, when being used as an air ambulance aircraft, it could carry a patient on a stretcher, which was loaded through a hatch in the aircraft's nose. The F.25 was evocative of the pre-war G.I design. The F.25 was based upon the design of the Difoga 421 aircraft, home-built and -designed during World War II by Frits Diepen, a Ford garage owner from Tilburg, the Netherlands. His intention was to create an easy to fly personal aircraft. Due to the war an aircraft engine was not available and instead it used a Ford V-8.
The Caproni Ca.308 Borea was a small airliner built in Italy in the mid-1930s.
The Civil Aviation Department Revathi was a light utility aircraft designed in India principally for use by that country's flying clubs.
The Focke-Wulf A 20 Habicht was an airliner developed in Germany in the late 1920s. It was a high-wing cantilever monoplane with fixed tailskid undercarriage. The fuselage was deep and seated four passengers in a fully enclosed cabin. The type was not bought by the airlines and only a few examples were built.
The SIAI-Marchetti SM.101 was a 1940s Italian single-engined light transport cabin monoplane designed and built by SIAI-Marchetti.
The Focke-Wulf S 2 was a trainer aircraft built in Germany in the late 1920s. It was a conventional parasol-wing monoplane with fixed tailskid undercarriage. The pilot and instructor sat side by side in an open cockpit. Only a single example was built.
The Heinkel HD 22 was a trainer designed in Germany during the 1920s. It was a conventional single-bay biplane with staggered wings braced with N-type interplane struts. The pilot and instructor sat in tandem, open cockpits, and the main units of the fixed, tailskid undercarriage were linked by a cross-axle.
The Hitachi TR.1 was a small airliner developed in Japan in 1938, produced in small numbers as the TR.2. It was a low-wing, cantilever monoplane with retractable tailwheel undercarriage and a fully enclosed cabin. The design strongly resembled the Airspeed Envoy that it was intended to replace in Japanese airline service. Testing of the TR.1 prototype commenced on 8 April 1938 at Haneda Airport, but it suffered a serious accident on 22 June due to a landing in which one of the main undercarriage units failed to extend.
The Hopfner HS-5/28 was a utility aircraft built in Austria in the late 1920s. It was a conventional, parasol-wing monoplane with seating for two occupants in tandem, open cockpits. The landing gear was of fixed, tailskid type with divided main units. Two examples were built with Walter NZ60 engines, followed by two more with the more powerful NZ85 for Swiss aeroclub use. One of these latter machines remained in service until 1934.
The Hopfner HS-8/29 was a utility aircraft built in Austria in the late 1920s based on the Hopfner HS-5/28. It used a modernised version of its predecessor's airframe, being a conventional, parasol-wing monoplane with seating for two occupants in tandem, open cockpits. The landing gear was of fixed, tailskid type with divided main units. The first prototype used the same Walter NZ 85 engine that the later HS-5/28s had used, but this was followed by 14 production examples with Siemens engines, and a single prototype with a de Havilland Gipsy III.
The Hopfner HV-6/28 was a small airliner built in Austria in the late 1920s for Swiss use. Unrelated to Hopfner's other airliners of the period, the HV-6/28 was a conventional, high-wing, strut-braced monoplane with a fully enclosed cabin. The main units of the fixed tailskid undercarriage were divided. The single example built was flown by Aero St. Gallen between 1929 and 1931, and then scrapped.
The Partenavia P.55 Tornado was a 1950s Italian high-performance competition and touring monoplane built by Partenavia. The Tornado was a small mid-wing cantilever monoplane with a retractable tricycle landing gear. The aircraft was powered by a nose-mounted Lycoming O-320 piston engine.
The Wassmer WA-80 Piranha is a French two-seat low-wing cabin monoplane trainer designed and built by Société Wassmer. Based on the same construction as the company's WA-50 four-seater, the WA-80 was a scaled down version. The prototype, registered F-WVKR, first flew in November 1975 powered by a 100 hp Rolls-Royce Continental O-200 engine. Wassmer appointed a receiver and suspended production in 1977 after 25 had been built.
The Renard R.17 was a Belgian four-seat cabin monoplane designed and built by Constructions Aéronautiques G. Renard. The high cantilever wing was an unusual feature when most contemporary aircraft still had braced wings. Designed as a high-speed transport for fresh flowers, no aircraft were ordered and the only R.17 was retained by the company until 1946.
The Renard R.30 was a prototype trimotor airliner built in Belgium in 1931. It was a strut-braced high-wing monoplane of conventional design with a fully enclosed flight deck and separate passenger compartment. One engine was mounted on the nose, while the other two were mounted on the leading edges of the wings. Construction was metal throughout, skinned in plywood and fabric.
The IMAM Ro.5 was a sport aircraft designed by Alessandro Tonini and produced by IMAM in Italy in the late 1920s.
The SABCA S.2 was an airliner built in Belgium in 1926.
