CONTROL CABLE TENSIONS
22. The tension of the control cables
should be checked with a
S.M.E. Mk.
3
tensiometer (Ref. No. IC/6134) at the
positions given in tbe following paragraphs.
They should be adjusted to the tensions
stated.
Aileron
control
23. AppJy the tensiometer
10
the cables,
accessible through the access holes in the
underside of the main planes, between ribs
5 and
6.
The tension should be between
40 and 50 lb.
Elevator control
24. Apply the tensiometer to the cables,
accessible through the triangular door on
the
port side of the fuselage, aft of the
cockpit. The tension should be between
35 and 40 lb.
Rudder control
2S. The rudder control is automaticaUy
loaded by the rubber compensator cord in
the nose of the fuselage. Its tension need
not be checked.

STATIC FRICTION LOADS
26. The static friction loads of the controls
should be checked with
a
spring balance
applied at the positions given in the follow
ing paragraphs. When checking the load,
move the controls thtough their full travel
in both directions and take the average
reading.
Aileron control
27. Apply the
spring
balance a t the top
of the control column; the average load
must not exceed 4 lb.
Elevator control
28. Apply the spring balance at the top
of the control column, Since the weight
of the elevators affects the spring balance
reading in both directions, the nverage load
will be half the difference between the
readings obtained during forward and aft
movement of the control column; this must
not exceed 2i lb.
Rudder control
29. Apply the spring balance at the foot
bar of the rudder pedals; the average load
must not exceed 71 lb.
