## Discrepancy

CAPTAIN REPORTED THAT LT AIRSPEED INDICATOR SHOWED MACH 0.50, SO AIRSPEED INDICATOR WAS REPLACED IAW MM 34-13-01, TESTED CORRECT.  AIRCRAFT WAS DISPATCHED BUT REJECTED TAKEOFF AT 80 KNOTS DUE TO LT AIRSPEED INDICATOR FAILED. CADC NR 1 AND 2 WERE TESTED IAW MM 34-16-00 BUT CADC NR 1 AIRSPEED INDICATION WAS ZERO. LT AIRSPEED INDICATOR WAS REPLACED AGAIN IAW MM 34-13-01, TESTED CORRECT.
