The IAR-22 was a single engine basic trainer built in Romania in about 1934. It was a low-wing monoplane with two seats in tandem and a fixed conventional undercarriage.

The IAR.22 was a wooden, low-wing monoplane with a fixed conventional undercarriage, seating two in tandem, open cockpits. The wings were built around two spruce box spars, with plywood webs; plywood covered the whole wing except for the fabric trailing edges. In plan, the wings were straight-tapered, with most of the taper on the trailing edge, but with rounded tips. The wing trailing edge carried ailerons but no flaps. The tailplane was also straight-tapered, though with the taper more equally distributed between leading and trailing edges. The elevators were split, with a cut-out for rudder movement, and were horn balanced. The fin was also straight-edged but the broad rudder, also horn balanced, had a curved trailing edge.

The fuselage of the IAR.22 was flat sided, tapering to the rear. It was a Warren truss structure with duralumin gussets; the forward fuselage was plywood covered, the remain fabric clad. Rounded decking, together with a head fairing behind the rear cockpit, gave the aircraft a slightly humped profile. The front cockpit was just behind the leading edge of the wing and the rear one at mid-chord. The nose line dropped slightly over the cowling of the 97 kW (130 hp) de Havilland Gipsy Major engine, an inverted air-cooled inline engine carried on a steel mounting and which drove a two-bladed propeller. The undercarriage had a wide track of over 2.5 m (100 in), with near vertical IAR-made shock absorber legs, split axles hinged at the fuselage centre line and trailing struts. The wheels had independent brakes but were not faired in.
