## Discrepancy

CORROSION OF RIGHT LOWER AFT SPAR CAP ASSY.  EXTENT OF CORROSION WAS PAST ALLOWABLE REPAIR LIMITS SET FORTH BY CESSNA A/C CO.  THE SPAR IS LOCATED DIRECTLY BEHIND THE EXHAUST AUGMENTORS AND IS BEING CORRODED BY THE EXHAUST EMISSIONS.  PERIODIC CLEANING OF THE FLAP WELL AREA AND CORROSION TREATMENT IS RECOMMENDED.  SPAR CAP ASSY WAS REPLACED WITH A NEW UNIT FROM CESSNA.
