## Discrepancy

CORROSION FOUND INSIDE OF THE BOTTOM OF THE OIL PAN AROUND THE PLUG BOSS.  THIS WAS DUE TO MOISTURE CONDENSING AND COLLECTING AT THE BOTTOM OF PAN.  IF THE AIRCRAFT IS GOING TO SIT FOR WEEKS ON END;SUBMITTER SUGGESTS ONE-QUARTER OF THE OIL BE DRAINED AS THIS WILL FACILITATE REMOVAL OF THE COLLECTED MOISTURE.
