Crunch Alert (USA) - hugely serious but (apparently) non-fatal

The tension springs are an essential part of the control circuit to avoid
flutter. Inspection of cables where they go through the adjustment guides
is a standard item on inspection check lists.
It might be smart for everybody to adjust their pedals all the way
forward
and back and see if the guy who did our inspection nissed something.

Not sure that flutter is the reason for the springs. They are necessary to
to tension the cables when the rudder pedals are moved for and aft on some
gliders. Some gliders do not have springs in the cable at all
