## Discrepancy

DUE TO A STALL WARNING INDICATION, TAKEOFF WAS ABORTED AT AN ESTIMATED SPEED OF 108 TO 110 KNOTS.  *S/D*  CHECKS WERE PERFORMED ON THE ANGLE OF ATTACK SENSORS, STALL WARNING COMPUTERS, AND STICK SHAKERS ON BOTH SYSTEMS.  EVERYTHING CHECKED NORMAL.  THE STALL WARNING COMPUTER NUMBER 2 WAS REPLACES FOR PRECAUTIONARY REASONS.  SYSTEM CHECKS WERE PERFORMED AGAIN WITH NORMAL RESULTS.  THERE HAVE NOT BEEN ANY STALL WARNING PROBLEMS SINCE.
