The design goals for the A-28 included twin engines for safety over hazardous terrain, a payload of 300kg (700lb) with four seats, 10 hours endurance, as well as good short and rough field capabilities. The resulting design features a cantilever low-wing, a four-seat enclosed cabin accessed through a hinged windshield, a T-tail, fixed conventional landing gear and twin engines in tractor configuration.
The aircraft has mixed construction, with the forward fuselage made from fibreglass and the tail cone of aluminium sheet. The wings and tail are all-aluminium, while the control surfaces are aluminium frames covered in doped aircraft fabric. Its 121NaN1 span wing employs a TsAGI P-IIIA-15 airfoil, has an area of 13.4m2 and mounts flaps. The standard engines fitted are two 800NaN0 Rotax 912 or two 1000NaN0 Rotax 912S powerplants. The conventional landing gear fits wheel pants and features a steerable tailwheel.[2]
The A-28 has an empty weight of 530kg (1,170lb) and a gross weight of 1100kg (2,400lb), giving a useful load of 570kg (1,260lb).
One example was registered in 2001 in the United States with the Federal Aviation Administration in the amateur-built category, but on 18 October 2004 it was deregistered and exported to Ukraine.[3] [4]
