AILERONS – DESCRIPTION AND OPERATION
27- 20 AILERONS
DESCRIPTION AND OPERATION
Aileron control system uses push-pull rods and bellcranks inside wings 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). The push-pull rod then crosses the wing’s fake spar to
transmit motion. Linkage length is adjustable.
