## Discrepancy

DURING POST-MAINTENANCE ENGINE RUNS, HYDRAULIC FLUID WAS NOTICED LEAKING FROM LINE.  FURTHER INVESTIGATION REVEALED A SERIES OF CORRODED PIN HOLES LOCATED UNDER THE LINE IDENTIFIER TAPE PLACARD.  THIS SITUATION IS SIMILAR TO THE PROBLEM THAT AFFECTED THE RUDDER BIAS BLEED AIR LINES ON THE RC1125-700 (SB 27-157R2).  SUBMITTER RECOMMENDS PLACARDING TAPE BE REMOVED FROM LINES AND SURFACES AND BE VISUALLY INSPECTED FOR CORROSION.  OPERATOR CONTROL NR 96-002.
