Have your mechanic check the Cessna structural repair section of the maintenance manual, section 19-40. If the crack is across the corrugation and doesn't go to the trailing edge then it needs to be fixed as soon as practible.
It can be repaired with a patch inside the aileron pretty easily but you would need to remove it to check the balance.
The ailerons have a bow in them about 2/3 of the way to the tip, is the wing tip straight? Alan
