## Discrepancy

LEFT AND RIGHT VOLTAGE REGULATOR AND GROUND VENT FAN CIRCUIT BREAKERS ALL TRIPPED SIMULTANEOUSLY DURING FLIGHT AND WOULD NOT RESET.  AIRCRAFT RETURNED TO FAI WITHOUT INCIDENT.  MAINTENANCE FOUND SMALL BUSS BAR IN THE CIRCUIT BREAKER PANEL HAD A LOOSE CONNECTION.  ATTACHMENT HARDWARE WAS REPLACED AND BUSS BAR WAS SECURED WITH GOOD RESULT.  AIRCRAFT WAS RETURNED TO SERVICE.
