## Discrepancy

THE NR 2 ENGINE CHIP LIGHT ILLUMINATED ENROUTE TO A SCENE CALL.  THE PILOT IMMEDIATELY ABORTED THE FLIGHT AND RETURNED TO BASE LESS THAN 3 MILES AWAY.  UPON ARRIVING AT THE BASE, THE MECHANIC INSPECTED THE CHIP PLUGS AND FOUND METAL ON THE M05 MAGNETIC PLUG AND THE FWD LT HORIZ ELECTRIC CHIP PLUG.  THE CHIPS FROM BOTH PLUGS WERE SENT FOR ANALYSIS.   THE RESULTS FROM THE LAB ANALYSIS INDICATED THE SOURCE WAS THE HIGH SPEED BEARING MATERIAL.  IAW MFG.
