57-60-00 AILERONS
Description and Operation
The ailerons are constructed in the same manner as the wing
but with single chamber spar. They are supported at four
points in spherical bearings. In addition the aileron tip has a
shielded horn balance. Furthermore the ailerons are equipped
with spades to decrease pilots forces. To prevent flutter the
ailerons are mass balanced in the overhanging leading edge
as well as in the horn balance.
The layer sequence of the ailerons is shown in Figure 4.
All composite parts, as protection against moisture and UV
radiation, are coated with an unsaturated polyester gel-coat,
an acrylic filler and finally with an acrylic paint.
For repair of composite parts refer to Chapter 51.
