## Discrepancy

PIT - FLT 400 - DESCENDING THROUGH 5000 FEET, THE LEFT GENERATOR DROPPED OFF LINE.  WHEN THE CREW TRIED A RESET, THE GENERATOR AGAIN TRIPPED OFF LINE AND THE CROSS-TIE RELAY TRIPPED.  THE CREW WAS WITHOUT AC POWER.  THE APU WAS STARTED AND POWER RESTORED.  MAINTENANCE REPLACED THE GENERATOR CONTROL PANEL.  (M)
