Designed by Hermann Pohlmann during the late 1920s, it incorporated the all-metal construction and various other principles practiced on Junkers' larger aircraft of the era.

The A50 had a streamlined fuselage composed of corrugated duralumin, a low-mounted cantilever wing, and proportionally large flight control surfaces.

During the following year, a series of eight FAI world records for altitude, range, and average speed were set on a floatplane variant of A50.

[1] It had the same modern all-metal construction, covered with corrugated duralumin sheet, as larger Junkers passenger planes.

[1] In June 1930, a series of eight FAI world records for altitude, range and average speed were set on a floatplane variant of A50, powered by the Armstrong Siddeley Genet II 59 kW (79 hp) engine.

[3][4] The Junkers A50 was a sports plane that featured a conventional configuration, all-metal construction, a low-mounted cantilever wing, and a stressed corrugated duralumin exterior.

[6] The A50 conformed with several conventions for Junkers-built aircraft, such as the placement of the pilot in the rear seat while the passenger sat in the forward position.

[7] The fuselage was a precisely streamlined tube of corrugated duralumin; in spite of its extensive use of metal, it was carefully designed so that achieved the typical weight limits of mixed-construction aircraft (e.g. those that used fabric and wood).

[10] The two seats present in the cockpit, used by the pilot and a single passenger, were relatively well-upholstered, broad, and fitted with an adjustable back and arm rests.

Two separate baggage compartments were provided for the carriage of even particularly heavy suitcases; one, positioned between the two seats, was within easy reach of either occupant throughout the flight.

Structurally, it was relatively simplistic, dispensing with many typical supporting devices, such as ribs; this simplicity benefitted both production and service staff alike.

[9] The aircraft's proportionally large flight control surfaces, thus only necessitating slight deflections, were actuated using a series of adjustable push rods.

[12] It was typically powered by a single Armstrong Siddeley Genet II air-cooled radial engine, which was mounted on an easily-removable frame upon the forward bulkhead, which functioned as a firewall.

This new A50 features modern avionics, a 100 hp (75 kW) Rotax 912iS engine driving a composite MT-Propeller, and a ballistic parachute.
