CAP 222 ailerons are totally new. They use
five hinges which transfer most of the bending loads to the wing
rear spar. The advantages (compared with a three-hinge aileron)
are:
ailerons are much lighter stress
stress supported by each hinge
is smaller
stress supported by rear spar
and wing skin (buckling) is smaller
The new aileron design has been taken into
account when redesigning the wing, and new ribs has been added
in front if the hinges.
