Section C
If control stick should feel unusually hard, reduce cable tension as this may be the prima-
ry cause for malfunction (ref. Section B); also check that parts of the link system posi-
tioned under seats are properly greased.
If control stiffness persists, check integrity of bellcranks or pulleys and insure that cable
has not come off pulleys.
Alignment of moving surfaces with half-wing must be done using outboard trailing edge
as reference. Further lateral corrections (aircraft leans to one side) may be carried out ad-
justing trim tab located on left aileron trailing edge.
4 - HORIZONTAL TAIL
Horizontal tail is an all moving type, that is, the stabilizer and elevator form a single, uni-
form plane called stabilator which rotates about an axis normal to fuselage centre line at
the desired pitch setting.
The stabilator structure (see fig. C-5) is constructed of a light alloy tubular spar (1) to
which a series of ribs (2) and an light alloy leading edge (3) are riveted. Entire structure is
Dacron covered.
A trim tab (4) provides stick force adjustment and longitudinal compensation through an
electric actuator controlled by pilot. Tab is split in two halves interconnected at the sup-
port brackets (5) and attached to the stabilator through four external hinges (6) that allow
immediate inspection.
