## Discrepancy

AIRCRAFT WAS EN-ROUTE TO HOSPITAL WITH A PATIENT TRANSFER WHEN THE PILOT ENCOUNTERED AN ENG CHIP LIGHT INDICATION.  PILOT IMMEDIATELY PERFORMED AN UNSCHEDULED LANDING IN A FIELD NEARBY.  PATIENT WAS TRANSFERRED BY AMBULANCE. MECHANIC ARRIVED ON SCENE & PULLED BOTH CHIP DETECTORS TO DISCOVER LARGE CHUNKS OF METAL DEBRIS.  ENG CHANGE IN PROGRESS AT THIS TIME.  THIS ENG WAS INSTALLED ON THIS ACFT AT 443 HOURS TSN IN WHICH WAS PREVIOUSLY REPAIRED FOR METAL IN OIL.  FURTHER INVESTIGATION OF ENG UPON RETURNING TO REPAIR FACILITY.
