6.4 Check / Adjustment
6.4.1 Check of play in control
Admissible plays in control are mentioned in the following table:
Control
Admissible play
Area to measure play
longitudinal
max 4 mm
(5/32 in)
at the end of the control stick in longitudinal axis of the airplane
lateral
max 4 mm
(5/32 in)
at the end of the control stick in lateral axis of the airplane
directional
max 4.8 mm
(3/16 in)
on pedals in longitudinal axis of the airplane
trim tabs
max 3.2 mm
(1/8 in)
at the end of the trim tab
wing flaps
max 3.2 mm
(1/8 in)
at the end of the wing flap
CAUTION:
IF THE MEASURED PLAYS EXCEED VALUES MENTIONED IN THE TABLE
THEN ELIMINATE THE CAUSE OF IT AND REPEAT MEASURING.
Measuring procedure
a) Measure all plays three times and write down average values.
b) Perform measuring with the blocked control surfaces. Before measuring it is necessary to push
down the control surface by hand several times (max force of 5 kg (
11 lbs
) in the direction of the
control surface deflection, so that the control system is unblocked and plays can be more easily
identified.
c) 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.
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 end of the control stick (see Fig. 6-15).
