Conventional swept-back stressed skin construction tail surfaces were a 35° sweptback fin and 40° swept tail-planes just above the rear fuselage. Control surfaces were Ailerons on each wing, a rudder on the fin and elevators on the tail-planes. The fuselage was a two step design with a high length to beam ratio to improve rough water handling, v-section planing bottom, two steps and was divided into nine water-tight compartments the forward and rear compartments being pressurised. Engine nacelles for the Lyul'ka AL-7F engines were attached to the fuselage sides under the wing centre-section.
