## Discrepancy

DURING TAKEOFF ROLL RUDDER BECAME VERY STIFF AND HARD TO MOVE, AS IF YAW DAMPNER WAS ENGAGED.  AT LOW POWER SETTINGS RUDDER IS FREE AND EASY TO MOVE.  DID A STATIC RUN UP TO FULL POWER AND RUDDER BECAME PROGRESSIVELY HARDER TO MOVE PAST THROTTLE MID RANGE.  RAN BOTH ENGINES AND PERFORMED FUNCTIONAL CHECK OF RUDDER BIAS SYSTEM IAW RAYTHEON HAWKER 800XP AMM CHAPTER 27-20-00 PAGE 509.  SYSTEM OPS CHECKS GOOD.
