## Discrepancy

DURING A TOUR FLIGHT THAT DEPARTED AIRPORT, THE MGB CHIP LIGHT ILLUMINATD 3 MINUTES INTO THE FLIGHT.  THE PILOT RETURNED TO DEPARTURE WITHOUT INCIDENT.  THE MECHANIC INSPECTED THE CHIP PLUGS AND FOUND METAL ON LOWER PLUG.  THE OIL WAS CHANGED AND THE CHIP PLUG LIGHT ILLUMINATED AGAIN.  THE MAIN GEAR BOX AND OIL COOLER WAS CHANGED.
