## Discrepancy

THE ACFT WAS ON A TRAINING FLIGHT IN CRUISE, THE LT GENERATOR AND STARTER LIGHT FLICKERED AND THEN STAYED ON.  THE LT ENG WAS SHUTDOWN AND THE ACFT RETURNED TO BASE.  MX INSPECTED THE SYS AND FOUND THAT CONTACTOR (PN A-703G) WAS FAULTY.  ALSO THE GCU WAS FOUND TO BE FAULTY.  THE CONTACTOR AND THE GCU WERE CHANGED WITH SERVICEABLE UNITS AND THE SYS TESTED SERVICEABLE.
