## Discrepancy

GROUND HANDLING TRU CB ON P34 POPPED.  REPLACED TRU AND TRU CB PER MM, NO HELP.  CB APPEARED TO POP WHEN UNDER LOAD AND WOULD ONLY STAY IN WHEN FWD AND AFT CARGO HANDLING CBS WERE PULLED.  REMOVED AND CLEANED CONNECTOR D4926P.  INSPECTED WIRING IN P34 PANEL AND ACCOMPLISHED SHAKE CHECK OF WIRING AROUND P34 PANEL.  CB NOW STAYS SET EVEN WHEN UNDER HIGH LOAD.
