## Discrepancy

SHORTLY AFTER TAKEOFF, NR 1 ENGINE THRUST WENT TO 85 PERCENT N1, THEN UNABLE TO INCREASE OR DECREASE THRUST.  OPENED FUEL CROSS FEED VALVE AND THEN ABLE TO CONTROL ENGINE POWER.  RETURNED TO SFO.  REPLACED THE MAIN FUEL PUMP AND THE MEC.  RAN ENGINE AT HIGH POWER WITH ALL PARAMETERS NORMAL.  NO PROBLEMS.
