## Discrepancy

ON INITIAL CLIMB CREW NOTICED FUEL LEAKING FROM THE WING AND RECEIVED A CAS MESSAGE. CREW REPORTS VISIBLE FUEL COMING FROM RH WING AFTER TAKING OFF FROM CAMARILLO CA TO TAHITI.  AIRCRAFT DIVERTED TO KLAX AND PERFORM AN OVERWEIGHT LANDING. DISCUSSION WITH BOMBARDIER IDENTIFIED AIR BUBBLE ENTRAPMENT AT FUEL LEVEL SENSE PROBES RESULTING IN OVERFILLING OF THE WING TANKS FROM THE CENTER TANK DUE TO INACCURATE SIGNAL TO THE AUTO-TRANSFER SYSTEM (FALSE LOW LEVEL). RESOLUTION REQUIRES INSTALLATION OF ADDITIONAL RELIEF HOLES IN WING FUEL TANK BAFFLES THROUGH A MODSUM TO FACILITATE IMPROVED VENTING OF ENTRAPPED AIR.
