## Discrepancy

CORROSION LEFT WING UPPER FORWARD SPAR CAP ASSEMBLY.  EXTENT OF CORROSION WAS PAST ALLOWABLE REPAIR LIMITS SET FORTH BY CESSNA A/C CO.  THE SPAR IS BEING CORRODED BY EXHAUST EMISSIONS PENETRATING INTO THAT AREA.  PERIODIC CLEANING OF THIS AREA AND CORROSION TREATMENT IS RECOMMENDED.  THE SPAR CAP WAS REPLACED WITH A NEW UNIT FROM CESSNA.
