## Discrepancy

DURING THE RETURN FLIGHT AFTER THE PATIENT HAD BEEN DROPPED OFF, THE MGB CHIP LIGHT ILLUMINATED IN FLIGHT.                                                                                   
   I IMMEDIATELY REDUCED POWER AND LOOKED FOR A SUITABLE LANDING SPOT, USING MY CREW TO HELP LOOK FOR OBSTACLES. I MONITERED THE MGB TEMP AND MGB P LIGHTS. NEITHER ILLUMINATED. UPON LANDING I CONTACTED DISPATCH, MAINTENANCE, AND THE PMOC. THE LANDING WAS CARRIED OUT WITHOUT INCIDENT.       
   INSPECTED CHIP DETECTOR AND PERFORMED FAULT ISOLATION TEST IAW AMM 05-50-00,6-1 AND AMM 60-00-00,1-1 AND FOUND NO DEFECTS.  PERFORMED GROUND RUN AND COULD NOT DUPLICATE.
