## Discrepancy

DURING NORMAL CRUISE FLIGHT, THE PILOT REPORTED THE ENG CHIP LIGHT ILLUMINATED.  THE PILOT PERFORMED A POWERED PRECAUTIONARY LANDING ON A PRIVATE, CLEARED LOT WITHOUT INCIDENT.  AFTER INVESTIGATION OF THE CHIP PLUGS, BY A CERTIFICATED MECHANIC, IT WAS DISCOVERED THAT BOTH BOTTOM & TOP PLUGS WERE COVERED WITH SMALL TO MEDIUM METAL PIECES.  THE PLUGS WERE CLEANED & REINSTALLED & AN ENG START WAS ATTEMPTED.  THE CHIP LIGHT ILLUMINATED ON STARTUP, THE START WAS ABORTED.  THE ACFT REMAINED OVERNIGHT UNDER GUARD & WAS RECOVERED BY CRANE & LOWBOY TRUCK ON THE MORNING OF 03 25 2016 & ACFT RETURNED TO THE HANGER FOR ENG CHANGE & FURTHER INVESTIGATION.  NO DAMAGE SUSTAINED TO THE ACFT OR PAXS.
