The 1934 CNIAR IAR-22 was a wooden construction, fabric-covered two-seat dual-control trainer/tourer. It has two seats in tandem and a fixed conventional undercarriage.
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 perpendicular 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.
It was reported that the IAR.22 "gave very satisfactory results in tests" conducted by the Romanian Air Ministry's Acceptance Commission but there is no record of its adoption by the Romanian Air Force. The design allowed for engines of up to 225 kW (300 hp) to be fitted: the intention was that it should be suitable for wireless, camera and gunnery training.
