Doc. No. 6.01.05-E  Revision 3  26-May-2003  Page 7 - 1 

7.1 INTRODUCTION
Chapter 7 contains a description of the airplane and its systems, together with operating instructions.
For details about optional equipment see Chapter 9.
7.2 AIRFRAME
Fuselage
The GFRP fuselage is of semi monocoque molded construction. The fire protection on the firewall is of a special fire-resistant matting, which is covered on the engine side by stainless steel cladding. The two main bulkheads are GFRP/CFRP items.
Wings
The wings have a front and rear spar; each wing has a top shell and a bottom shell - a ‘fail-safe‘ concept. The wings, as well as the ailerons and flaps, are made of GFRP/CFRP, and are principally of sandwich construction. An aluminum fuel tank is installed in each of the wings.
Empennage
The airplane has a ‘T’ tail of GFRP semi monocoque construction. Both the stabilizers have twin spars and a skin with no sandwich. Rudder and elevator are of sandwich construction.

7.3 FLIGHT CONTROLS
The ailerons, elevator and wing flaps are operated through control rods, while the rudder is controlled by cables. The flaps are electrically operated. Elevator forces can be balanced by a trim tab on the elevator, which is operated by a Bowden cable.
Ailerons
Construction:  GFRP/CFRP composite sandwich. 
Hinges:  There are 4 hinges, which are hinge pins mounted in an aluminum bracket. They are secured in position by a roll pin. The absence of this roll pin can lead to the loss of the hinge pin and a consequent loss of flight safety. 
Operation:  A rod-end bearing is screwed into a steel push rod and locked by means of a jam nut which has locking varnish applied to it. Damage to this varnish can indicate a twisting and thus a change to the adjustment. The connection between the rod-end bearing and the control horn is a bolt, the nut of which is likewise sealed with locking varnish. 
The aluminum control horn is attached to the aileron with 3 screws.

Flaps
Construction:  GFRP/CFRP composite sandwich.
Hinges:  There are 6 hinges, which are hinge pins mounted in an aluminum bracket. They are secured in position by a roll pin. The absence of this roll pin can lead to the loss of the hinge pin and a consequent loss of flight safety. Another aluminum fitting is located at the fuselage and is attached to a torsion tube. The torsion tube is located in the fuselage, creating a connection between the left and right flaps.
