27-10-00 AILERON CONTROL
(Refer to Figure 10) The aileron (3) is directly mechanically
linked to the control sticks (1, 2) by the aileron actuator arm
(4) with spade arm, push-pull rods (5), bellcranks (6) and the
torque tube (8). The bell cranks have two sealed ball bear-
ings. Each aileron is mounted at four points in spherical
bearings pressed into aluminium hinge arms. For lightning
protection reasons each hinge arm is electrically bonded to
the corresponding attachment bracket at the aileron by bond-
ing braids. The rod end bearings of the push-pull rods located
in the wing are also interconnected by bonding braids. The
travel stops (7) are located at the torque tube (8) next to the
rear control stick.
To reduce pilot's hand forces the ailerons are equipped with
spades. The hinge line of the ailerons is positioned at 25% of
the aileron chord. In addition a shielded horn balance of 55%
wing chord is provided at the tip of the aileron with a span
of 250 mm.
Two access panels on the bottom surface of each side of the
wing allow access to the main parts of the aileron control.
