AIRFRAME
2.3.1. RUDDER SURFACE
The rudder structure is made-up by a single aluminium spar (1) and ribs (2). Aluminium
skin panels (3) are riveted to the above elements. It is connected to the fin through two hing-
es; at the lower hinge a bellcrank (4) is connected for the movement transmission.
A trim tab (5) provides stick force adjustment and lateral compensation through a rocker
switch located between pilot and co-pilot seats.
