TECHNICAL DESCRIPTION, OPERATING, MAINTENANCE AND REPAIR MANUAL
1.6.9.2 Lateral control system
A control stick lateral motion (1) is transferred by rod (2) into a pin joint (BV), which
allows a disconnection of the rod in case of a derigging of a wing. An access to this
joint (BV) is allowed through an access hole at a model with a fixed undercarriage and
through a main wheel well at a model with a retractable undercarriage.
Long rod (3) guides from the end of the wing central panel to the two-arm lever (4),
which a console with the bearings is attached at the wing main spar. This lever provides
a necessary differentiation of the aileron deflections. Two-armed lever angular
displacement is transferred at aileron by short rod (5). A longitudinal movement of a
short rod is transferred into an aileron root rib, which a point of rotation is below a
upper surface wing. The long rod (3) is guided in a sliding guide rollers (6) which are
located in the wing root rib and in the wing auxiliary rib. Its guide surfaces are
equipped with a riveted sliding capsulars on a rod. The range of the control stick
deflection is adjusted by stops (AS) on the consoles of the torsional tube (TR). The
stops are screws type with the fastening nut.
