## Discrepancy

AIRCRAFT WAS GROUNDED. DURING TAKEOFF, THE THRUST ON THE RIGHT ENGINE FAILED TO ACCELERATE AT THE SAME RATE AS THE LEFT ENGINE CAUSING ASYMMETRICAL THRUST.  ATTEMPTED SECOND TAKEOFF AND RIGHT THRUST STILL SLOW. ACCOMPLISHED AUTO THROTTLE CHECKS IAW AMM 22-31-00, EEC BITE CHECK IAW AMM 73-21-00 AND ENGINE ACCELERATION CHECK IAW AMM 71-00-00-5. OPERATIONAL CHECK GOOD.
