It features a strut-braced high-wing, with "V"-struts and jury struts, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.[1][2]

The aircraft is made from a combination of composites and aluminum sheet, with its tailboom made from a single large diameter aluminium tube and the wings and tail surfaces covered in aluminium. Its 9.45 m (31.0 ft) span wing has an area of 16.65 m2 (179.2 sq ft), is supported by V-struts and mounts flaps. The standard engine available is the 100 hp (75 kW) Rotax 912ULS or Rotax 912iS four-stroke powerplant.[1][2][4]

The AC4 can accommodate one pilot and one passenger and was also designed for aero-towing gliders. It can also accommodate a stretcher for Medevac missions. It received European European Aviation Safety Agency type certification to the Certification Specification for Light Sport Aeroplanes (CS-LSA) on 6 August 2015.[5][1][2]
