## Discrepancy

CAPTAIN REPORTED THAT AT THE BEGINNING OF THE TAXI, APPEARED THE AIR SPEED A/S FLAG IN THE LT AIRSPEED INDICATOR. IT WAS PERFORMED A RESET AND THE CADC SWITCH WAS CHANGED OF POSITION, BUT THE TROUBLE CONTINUED.  AIR SPEED INDICATOR WAS REPLACED AND SYSTEM TESTED IAW M/M 34-13-00, ALL CORRECT.
