Single-engine low-wing cantilever monoplane of a metal construction. A fuselage built of a frame in front part, semi-monocoque in rear part, duralumin covered. Trapezoid three-part wing, duralumin covered, fitted with split flaps. Conventional tail, steering surfaces were covered with canvas. A tail fin was high, trapezoid. The plane had four seats in two rows, with twin controls in front. All were placed under a slim partly glazed canopy, sliding rearwards. At the rear, there was some luggage space. Inline engine in front, with two-blade tractor propeller V-410 of a variable pitch. Retractable inverted tricycle gear. The main gear's wheels are only half-hidden in wings, making emergency landings safer. Fuel tanks were in wings, there could be also fitted small teardrop tanks to wingtips.
