Figure 7-2: Aileron-Rudder Interconnection
Aileron Rigging
A. Assure
the
ailerons are attached and
the system push tubes are
assembled, except for the two lateral
push rods in the fuselage. Ensure
that flaps have been rigged. Rig the
ailerons as follows:
B. Clamp the ailerons at the trailing
edge of the wing tip in the neutral
position. Ailerons are in neutral
when ailerons are 1/8" below flap
trailing edge.
C. Adjust the length of the push rod
from aileron outboard wing bell crank
until inboard wing bell crank is
perpendicular to the rear spar, both
sides. This can be checked through
the inspection holes just forward of
the rear spar.
D. Attach the lower, lateral fuselage
push rod between the left fuselage
idler bell crank and the right fuselage
bell crank, adjusting the length of the
rod to fit those items.
E. Install the upper, lateral fuselage
push rod from right fuselage bell
crank to control stick torque-tube
fitting. Adjust the length of this push
rod to center the control stick.
F. Clamp control stick in center position
and free clamps on aileron. Set
trailing edges of ailerons 0.125-inch
below trailing edge of flap trailing
edge by lengthening push rod from
aileron to outboard wing bell crank.
G. Adjust and lock the aileron stops,
accessible through the inspection
holes forward of the aileron, for the
required travel. Aileron up travel
should be 21 (±1) degrees and down
travel should be 17 (±1) degrees.
H. Go back through system and lock all
check nuts.
I. To adjust the springs in the rudder-
aileron interconnect system, clamp
the rudder and ailerons in the neutral
position and adjust the turnbuckles
until the springs are the same length.
