4.11 Control surfaces deflection setting
Control surface deflections of a new aircraft are set by the manufacturer. Deflections are adjusted
to values specified in the Control Surfaces Deflection Record enclosed in this Manual.
A neutral position of the control surfaces and controls is used as a base for adjustment of
deflections.
4.11.1 Aileron deflection adjustment
A range of deflections are set using adjustment screws on lateral control stops located on a
console of the left/right control column.
The aileron neutral position can be adjusted with the adjustable end of the short rod inside the
cockpit. Or with the adjustable end of the longer rod inside the wing (when the screw cap on the
lower wing surface is removed).
The aileron differential (difference between a lower and upper deflection) can be adjusted with the
adjustable end of the rod connecting the two-armed lever inside the wing and the hinge. The
adjustable rod end is accessible when an aileron is deflected upward.
4.11.2 Flap deflection adjustment
Flaps deflection is determined by cut-outs in a changing gate on the flap control lever inside the
cockpit. Use the following procedure to adjust flap deflection:
Remove the baggage compartment bottom cover which will allow access to a rod connecting the
flap control lever and a lever welded on a tube connecting the left and right flap. Use the
adjustable rod end to adjust the flaps in the position "RETRACTED" .
The deflection of the left flap against the right flap may be adjusted when the eccentric pin is
moved a slight amount. The pin is inserted into the groove of the flap root.
See Figure in par. 2.3.11.9 for adjustment points.
4.11.3 Elevator deflection adjustment
The range of elevator deflection is determined by the control stick stops setting. The "Push in" stop
may be adjusted with an adjustment screw. To adjust an upward deflection, fully pull the control
stick rearward. Then measure the elevator upward deflection and compare it with the one
specified
–
if required adjust the deflection with the adjustable end of the elevator control rod or
with the adjustable end of the rod below the baggage compartment cover. When the upward
elevator deflection is adjusted, fully push the control stick and adjust a stop so that an elevator
downward deflection corresponds with that one specified.
See Figure in par. 2.3.11.7 for adjustment points.
