The PWS-52 was a Polish sports aircraft of 1930, a single-engine high-wing monoplane, constructed by the Podlaska Wytwórnia Samolotów (PWS), that remained a prototype.

The aircraft was first flown in early July 1930 by Franciszek Rutkowski in Biała Podlaska, weeks before the contest.

[1] The modified aircraft was ready in April 1931, and Lewoniewski flew it around Poland on 15 August 1931, on a distance of 1755 km without landing, with one passenger.

Lack of funds and problems of the PWS factory caused the plan to fly around the world to be abandoned.

A fuselage was built on a steel frame, covered with canvas and aluminium in engine part.

The aircraft used 4-cylinder air-cooled straight engine de Havilland Gipsy I in front, 85/95 hp nominal/take-off power, later replaced with de Havilland Gipsy III, 120 hp, with two-blade wooden propeller of a fixed pitch.
