The aircraft is a twin-engined shoulder- wing aircraft in fiber composite construction with wings one behind the other, which are connected by the engine pods of the engines. The main landing gear can be retracted into the motor nacelles, the nose wheel into the nose of the fuselage. The machine initially had a T- tail , which was replaced after the first 51 test flights by a double tail girder with vertical stabilizers and an intermediate horizontal stabilizer .
