## Discrepancy

DURING INSPECTION, AILERON CONTROL WAS DISCOVERED TO HAVE UNUSUALLY HIGH RESISTANCE.  RESISTANCE WAS EVENTUALLY ISOLATED TO THE LEFT AILERON.  BOTH BEARINGS WERE REPLACED AND THE OUTBOARD BEARING WAS FOUND ALMOST FROZEN WITH CORROSION.  THESE ARE SEALED BEARINGS AND HAD NO OUTWARD SIGNS TO INDICATE A PROBLEM.  NO REASON FOR THE CORROSION WAS NOTED.
