57-60-00 AILERONS
The ailerons are constructed in the same manner as the wing
but with a single chamber spar. They are supported at three
points in spherical bearings pressed into aluminium brack-
ets. Furthermore the ailerons are equipped with "glass fibre
laminate spades" to decrease pilots forces.
The layer sequence of the ailerons is shown in figure 4.
For protection against moisture and UV radiation all
composite parts 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.
