## Discrepancy

(CAN) THE ACFT WAS ON A WATER BOMBING MISSION & DURING LIFT OFF FROM A SCOOP THE CREW NOTICED THE ANNUNCIATOR LIGHTS IN THE COCKPIT SEEMED TO BE DIMLY LIT.  THEY DISCOVERED THAT THE GEN OUT ANNUNCIATOR WAS LITE ON BOTH SIDES INDICATING A DOUBLE GEN FAILURE.  THEY RETURNED TO BASE ON BATTERY POWER & LANDED WITHOUT INCIDENT.  MX DID AN INVESTIGATION & DISCOVERED THE RT GEN FAILED WHICH RESULTED IN THE LT TAKING THE ENTIRE LOAD.  DUE TO THE RAPID CHANGE IN LOAD, AGE OF SOME OF THE COMPONENTS IN THE SYS & THE STRAIN PLACED ON THE LT GEN SYS CAUSED IT TO FAIL AS WELL.  AS A PRECAUTION THE LT ENG DRIVEN GEN, LT MAIN CB & LT VOLTAGE REGULATOR WAS REPLACED.  THE RT ENG DRIVEN GEN WAS ALSO REPLACED.  ENG GND RUNS CARRIED OUT & THE ACFT WAS RELEASED TO SERVICE.
