2.12. RUDDER CONTROL

Rudder control constists of pedals, connecting rods, bearings, bowed cables. The left and right
pedals have independent-rotation axles. Two cables, the left one and the right one, are fixed on
the eyelets welded to the pedals. The cables are fixed on their other edge to the rudder bellcrank
which are installed on the rudder through a plate glued and screwed.
The control system ends with the connecting rods which link the pedals to the front undercarriage
(nose wheel).
The control stops of rudder steering are put on the support of the steering bellcrank. The rudder's
angle of steering on the left and on the right is of ±25°.
Adjustment of The Rudder Control

As for the adjustment you must:

nose wheel. Access to nose wheel – rudder pedals pushrods for check and adjustment are
two inspection holes on the firewall.
