## Discrepancy

ON TAXI AT KUOX OUR CREW EXPERIENCED A LOSS OF BRAKING DURING THE INITIAL BRAKE TEST. THE CREW USED THE EMERGENCY BACKUP BRAKE SYSTEM AND BROUGHT THE ARCRAFT TO AN UNEVENTFUL STOP. GROUND CREW WAS CONTACTED AND THE AIRCRAFT WAS REPOSITIONED BACK TO THE RAMP. TROUBLESHOOTING IS UNDERWAY AND WE HAVE A TECHNICIAN THAT IS VERY FAMILIAR WITH THE XLS SENT FROM OUR FACILITY TO THE AIRCRAFT TO ENSURE THIS ISSUE IS CORRECTED.
