2.1. F LAP CONTROL ( SEE FIG . C-4)
Flap control system is push-pull type. The torque tube (1) is hinged to the cabin
truss and connects the two moving surfaces by two levers (2). An electric linear
actuator (4) governed by a switch on instrument panel controls the torque tube
movements via a lever (3). Bolt, nut and cotter pin secure link.
Two push-pull rods (5) are connected to the ends of the torque tube (1) and are
located in the area between wing and fuselage thus facilitating inspection.
The two push-pull rods controlling flap movement feature an adjustable linkage
just before the roller bearings allowing trailing edge alignment.

2.2. A ILERON CONTROL ( SEE FIG . C-5)
Aileron control system uses push-pull rods and bellcranks inside wing and steel
cables and pulleys inside fuselage.
Layout of flight control system inside cabin includes two pairs of pulleys which
transmit movement from the two control sticks (1), linked in parallel by a rod (2),
to a small bar (3) located under the baggage compartment floor in correspondence
with main pushrods (5) issuing from the wings. Main rods (5) are connected to
the small bar (3) using two pins (4). The two main rods (5), are routed through the
ribs and are attached at opposite end to a bell crank (6) and a push-pull rod (7).
