## Discrepancy

REMOVED AND REPLACED (2) ANGLE BRACKETS IN LT WING WALKWAY THAT WERE ATTACHED TO THE RIB.  THESE WERE FOUND CORRODED DURING THE INSTALLATION OF INSPECTION PANELS BEING INSTALLED TO COMPLY WITH AD 02-26-02.  IT APPEARED WATER HAD BECOME TRAPPED INSIDE TRAILING EDGE OF WALKBOX AND CORROSION HAD SET IN.  THE RIB WAS NOT AFFECTED.  AIRCRAFT NEEDS SMALL DRAIN HOLE IN THIS AREA FOR DRAINAGE.
