7.2. AIRFRAME
7.2.1. Fuselage
The GFRP-fuselage is of semi-monocoque construction. The fire protection cover on the fire
wall is made from a special fire retarding ceramic fiber that is covered by a stainless steel plate
on the engine side. The main bulkhead is of CFRP/GFRP construction.
The instrument panel is made of aluminum.
7.2.2. Wings
The GFRP-wings are of semi-monocoque sandwich construction, and contain a CFRP-spar.
The ailerons and flaps are made from CFRP and are attached to the wings using stainless steel
and aluminum hinges.
The wing-fuselage connection is made with three bolts each. The A- and B- bolts are fixed to
the fuselage's root rib. The A-bolt is placed in front of the spar bridge; the B-bolt is near the
trailing edge on each side of the fuselage. The two main bolts are placed in the middle of the
spar bridge structure. They are accessible behind the seats and are inserted from the front
side. A spring-loaded hook locks both bolt handles, securing them in place.
7.2.3. Empennage
The rudder and elevator units are of semi-monocoque sandwich construction. The vertical
stabilizer contains a di-pole antenna for the VHF radio equipment, the horizontal stabilizer
contains an antenna for the NAV equipment (VOR).
