2.4 Landing gear
Nose wheel landing gear:
The nose wheel landing gear comprises the sprung nose wheel fork, the axle bolt,
the nose wheel, the nose wheel spar and the steering bar. Up until 2003, a steel
compression spring was used. However, since 2003 spring elements made of
polyurethane have replaced the pressure spring. The nose wheel fork is stored in the
nose wheel spar which passes through the fuselage tube and the engine mount and
is attached to the engine mount by means of a mounting bracket.

absorbers, trailing arms and spar struts as well as wheel axles and main wheels. The
individual elements of the landing gear are connected to each other by screws.
