## Discrepancy

DURING A TOUR FLIGHT, THE PILOT GOT A ENGINE CHIP LIGHT INDICATION. THE PILOT PERFORMED AN UNEVENTFUL UNSCHEDULED LANDING.  THE MX DEPARTMENT WAS DISPATCHED AND FOUND A METAL SLIVER ON THE UPPER ENGINE CHIP PLUG THAT WAS CAUSING THE LIGHT.  BOTH UPPER AND LOWER PLUGS WERE INSPECTED AND CLEANED. A GROUND RUN WAS PERFORMED WITH NO CHIP LIGHT.  THE PLUGS WERE INSPECTED AGAIN AND FOUND CLEAN.  THE ACFT WAS RETURNED TO SERVICE.
