## Discrepancy

PILOT REPORTED AFTER TAKEOFF, GOING THROUGH TRANSITIONAL LIFT, TRIM (YAW) TRIED TO MAKE NOSE YAW RIGHT, PILOT HAD TO EXCESSIVELY FIGHT TRIM.  MECHANICS HAVE CHECKED THE TAIL ROTOR CONTROL SYS, INSPECTED AND CLEANED T/R BLADE GRIPS AND PERFORMED AUTOPILOT CHECKS FOR THE TAILROTOR.  NO OBVIOUS PROBLEMS FOUND AND WE WILL BE PERFORMING A FLIGHT CHECK WHEN MAST MOMENT EXCEEDANCE DISCREPANCY IS CLEARED.
