## Discrepancy

AIRCRAFT REJECTED TAKEOFF AT 100 KNOTS AS A CONSEQUENCE OF 20 KNOTS SPEED INDICATION DIFFERENCE BETWEEN THE CAPTAIN AND FIRST OFFICER INDICATORS. THE PITOT SYSTEM WAS CHECKED AND TESTED BEING CORRECT, BUT THE LEFT SPEED INDICATOR WAS REPLACED AND THE SYSTEM TESTED IAW M/M 34-13-01, BEING CORRECT.  IN ACCORDANCE WITH THE MANUFACTURER INFORMATION ABOUT THE SPEED AND WEIGHT DURING THE REJECTED TAKEOFF, THE SPECIAL INSPECTION WAS NOT REQUIRED.
