## Discrepancy

DURING HMV AT SAA, CORROSION WAS FOUND ON THE EXTERNAL SKIN AT STA 1510 BETWEEN S-28R AND S-29R WHERE AN AIRPHONE ANTENNA HAD PREVIOUSLY BEEN MOUNTED.  SINCE THE ANTENNA IS NO LONGER USED, THE CORRODED SKIN WAS CUT OUT AND AN EXTERNAL REPAIR DOUBLER WAS INSTALLED PER BOEING REPAIR INSTRUCTIONS.
