7.1. INTRODUCTION
This Chapter provides description and operation of the airplane and its systems. Refer to Chapter 9
(Supplements), for details of optional systems and equipment.
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 fleece, that is covered by a stainless steel plate on the engine side. The main
bulkhead is of CFRP/GFRP construction.
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 aluminum hinges.
The wing-fuselage connection is made with three bolts each. The so-called A- and B- bolts are fixed to the
fuselage's root rib. The A-bolt is placed in front of the spar tunnel, the B-bolt lies near the trailing edge.
The two main bolts are placed in the middle of the spar tunnel (main bulkhead). They are accessible
between the backrests and can be inserted from the front side. A spring loaded hook locks both bolt
handles, thereby securing them.
7.2.3. Empennage
The rudder and elevator units are of semi-monocoque sandwich construction. The vertical stabilizer
contains a dipole antenna for the number 1 com. radio, the horizontal stabilizer contains an antenna for
the NAV equipment (VOR).
