## Discrepancy

PILOT REPORTS THAT IMMEDIATELY AFTER ROTATION, THE ELEVATORS BOUND IN THE MOSTLY UP POSITION.  AILERONS FUNCTIONED NORMALLY.  ELEVATOR TRIM WAS MOVABLE. POWER WAS REDUCED, AIRSPEED KEPT AT 135 KTS, AND THE ACFT RETURNED TO DEPARTURE.  ELEVATOR CONTROL WAS RESTORED ON TAXI BACK.  UPON INSPECTION, THE ELEVATOR CONTROL SERVO WAS FOUND TO BE INTERMITTENTLY BINDING AND JAMMED.
