Bring the rudder close to fuselage and fit it first onto the top and then to the bottom hinge.
The rudder must then be fully deflected to one side to provide access to the rudder bolts. Use a self-
securing, pre-glued M10 nut together with an aluminium washer and gently screw them onto the
bolt using size 10 spanner. To reach the other rudder bolt deflect the rudder to the opposite direc-
tion and repeat the up-stated procedure.
With both nuts tightened check full rudder deflections for smooth, unobstructed movement.
Detaching the rudder
Deflect the rudder to one side fully and unscrew the nut of the bolt with which the rudder is at-
tached to the bottom hinge. This is the bolt located in-between the central bolt (axis of rotation) and
the bolt holding the metal ropes. DO NOT touch these two bolts - unscrew the nut of the middle bolt
ONLY. Now deflect the rudder to the opposite direction and repeat the up-stated procedure.
After both bolts have been unscrewed, lift the rudder and detach it first from the bottom, then from
the top hinge.
