## Discrepancy

DURING GROUND RUN AFTER THE FIRST START OF THE DAY THE ENGINE CHIP LIGHT ILLUMINATED. MAINTENANCE INSPECTED THE UPPER AND LOWER ENGINE PLUGS AND FOUND 1 SLIVER ON THE UPPER PLUG.  A 30 MINUTE GOUND RUN WAS PERFORMED AND THE PLUGS WERE RECHECKED AND FOUND CLEAN.  THE ACFT WAS RELEASED TO SERVICE.
