      EV-97 Eurostar 
      is an ultralight aerodynamically controlled airplane intended especially 
      for tourist and free-time flying with the limitation to non-aerobatic 
      operation.  EV-97 EUROSTAR 
      is a single-engine whole-metal low-wing airplane of a semimonocoque 
      structure with two side-by-side seats. The airplane is equipped with the 
      fixed three-wheel landing gear with the controllable nose wheel. 
       Power unit standardly constists of the 
      four-cylinder four-stroke engine Rotax 912 (80 HP) and the fixed wooden 
      two-blade propeller V 230 C. Alternatively it is possible to install Rotax 
      912 ULS (S) (having power of 100 HP), Jabiru 2200 A (80 HP) and other 
      propellers according to the customer's wish. Airframe 
      The all-metal airframe of EV-97 
      Eurostar consists of metal stiffeners, frames and duralumin sheet 
      skin. Parts are mostly joint by pop rivets and by adhesive bonding. Some 
      of parts, especially those parts non-carrying high loads, are made of 
      fibreglass.
Fuselage 
      The fuselage is of semi-monocoque 
      structure consisting of stiffeners and duralumin skin. The fuselage 
      section is rectangular in the lower part and elliptical in the upper part. 
      The fin is an integral part of fuselage. The cockpit for two-member crew 
      is situated in the middle part of the fuselage and is accessible after 
      folding down the single-part organic glass canopy. The engine compartment 
      in the front part of fuselage is separated from the passenger compartment 
      by the fire wall to which the engine mount is attached.
WingThe wing of rectangular shape is of 
      single spar structure with the auxiliary spar on which ailerons and split 
      flaps are hinged. Riveting is used to assemble all individual design 
      parts. Fiberglas wing tips are riveted on the wing ends. At the 
      customer's wish the airplane can be equipped with the wing folding 
      mechanism, which enables hangaring with minimum room requirements.
AileronsEach half of wing is equipped with the 
      rectangular aileron. The aileron consists of ribs and skin, creating 
      cavity. The aileron is hinged on the wing by means of the swivel 
      throughout its length.
FlapsEach half of wing is equipped with the 
      split flap that takes about two thirds of half span of wing. The 
      rectangular flap consists of ribs and skin, creating cavity. The flap is 
      hinged on the wing by means of swivel throughout its length.
Horizontal Tail Unit 
      Horizontal tail unit, of usual type, 
      consists of the stabilizer and the elevator with the trim tab. Single spar 
      structure HTU of rectangular contour is composed of duralumin ribs, spar 
      and skin. HTU span is 2.5 m, which enables transportation of HTU on the 
      trailer without its disassembling.
Stabilizer 
      The rectangular stabilizer consists of 
      ribs and duralumin skin. The stabilizer is attached to the fuselage by 
      shifting on two pins in the front part and is secured by two bolts in the 
      rear part.
Elevator 
      The elevator consists of ribs and 
      duralumin skin. The elevator is hinged on the stabilizer by means of 
      swivel. The trim tab is hinged on the trailing edge of the elevator by 
      means of swivel.
Trim Tab 
      The elevator is equipped with one 
      rectangular trim tab. The trim tab consists of duralumin skin creating 
      cavity. The trim tab makes up about two thirds of HTU and is hinged on the 
      elevator by means of swivel throughout its length.
Vertical Tail UnitThe trapezoidal VTU of rectangular 
      contour consists of the fin and the rudder.
Fin 
      The fin part of VTU is an integral part 
      of the fuselage. Its structure is composed of two duralumin spars, root 
      rib, end rib and skin. The upper part of fin is closed by the laminate 
      cover on which the anti-collision beacon can be installed. The fairing 
      between the fuselage and the tail unit is made by the fibreglass cover.
RudderThe trapezoidal rudder is composed of 
      the duralumin spar, skin, upper and lower rib. The rudder is attached to 
      the fin by means of two hinges. The upper part of the rudder is closed by 
      the fibreglass wing tip.
