## Discrepancy

ABORTED T/O BELOW 100 KTS, LOSS OF CAPT'S IAS.  VISUALLY INSPECTED PITOT PROBE FROM FRONT OF TUBE, NOTHING OBVIOUS FOUND.  PRESSURIZED 2 OUT OF 3 PITOT SYS AT THE SAME TIME.  TRIED SEVERAL DIFFERENT COMBINATIONS AND DIFFERENT SWITCH SELECTIONS IN COCKPIT.  NO MATTER WHAT SELECTION WAS MADE, WHENEVER CAPT READING NR 1 PITOT INFORMATION, CAPT AIRSPEED MUCH SLOWER THAN F/O, UP TO 30 KTS DIFFERENCE.  REMOVED NR 2 ADM AND INSTALLED NR 1 POSITION IAW AMM 34-11-17.  PERFORMED INSPECTION/CHECK OF CAPT PITOT IAW AMM 34-11-15-200-801-A.  TUBE CLEARED USING COMPRESSED AIR.  PRESSURIZED ALL 3 PITOT SYSTEMS AND ALL AIRSPEEDS EXACTLY THE SAME.  ACFT CONSIDERED SERVICEABLE.
