Push on the control stick or the pedal by force of 3 kg (
6,6 lbs.
). Deflect the controlling
element to one side and read the deflection. Then push the control stick to the other
side and read the deflection. Sum of deflections presents plays in control.
6.4.1.2
Longitudinal control
Measure play at the end of the control stick at the blocked elevator in the neutral position.
The total play must not exceed 4 mm (
5/32 in
) at the top end of the control stick (see Fig.

Play in longitudinal control
6.4.1.3
Lateral control
Measure play at the end of the control stick by the measuring instrument from the fuselage
side at blocked ailerons in the neutral position. First block the right aileron and measure play
on the control stick, then measure play at the blocked left aileron. Total play of the control
stick must not exceed 4mm (
5/32 in
) at the top end of the control stick.
6.4.1.4
Plays in foot control pedals
Measure play at the end of pedals by the measuring instrument from the inner wall of the
bulkhead No.1 at the blocked rudder at neutral position and with the blocked nose landing
gear wheel against lateral slewing. Mutual total play between pedals must not exceed 5 mm
(
3/16 in)
on the pedal tube.
6.4.1.5
Play in trim tab control
Measure play in elevator neutral position. Set the balance tab to position “max on head" and
measure play at the end of the trim tab. Max play of the trim tab measured at the end of the
trailing edge must not exceed 3 mm (
1/8 in)
.
6.4.1.6
Play in wing flap control
Measure play in individual position of wing flaps (0°, 10°, 20° and 30°). Set the flap actuator
to individual positions. Measure play in wing flap control on the wing flap trailing edge. Max
play of the wing flap measured on the trailing edge must not exceed 5 mm (
3/16 in)
.
6.4.2
Check for friction in control system
Control system must function smoothly within the whole scope of deflections. There must not
be excessive friction or hitching in the control system. In case of failure detection, find out the
cause and eliminate the defect.
