## Discrepancy

(CAN) SHORTLY AFTER TAKEOFF, FLIGHT EXPERIENCED A HSTA RUNAWAY. ACFT HAD JUST DEPARTED RUNWAY  AND FLAPS WERE RETRACTED TO 0 DEGREES. AUTOPILOT DISENGAGED. TRIM SELECTION INPUT MADE.  STABILIZER TRIM CONTINUED TO RUN & ASSOCIATED AURAL ALERT SOUNDED.  IMMEDIATE ACTION CHECKLIST WAS COMPLETED, AS WAS QRH PROCEDURE.   MODERATE CONTROL PULL FORCES WERE REQUIRED TO FLY ACFT AT 10,000 & 250 KNOTS. CREW USED ACARS SYSTEM TO CALCULATE A WEIGHT & BALANCE, & REDISTRIBUTED CABIN LOAD TO ALLEVIATE CONTROL FORCES.
