## Discrepancy

DURING CLIMB AT 15K FT, RUMBLING SOUND HEARD AND LT ENG N1 IND 84.8% WITH A SPLIT IN ENG THROTTLES.  LT THROTTLE COULD NOT BE PUSHED BACK UP, SO RT THROTTLE WAS PULLED BACK TO MATCH LT ENG'S N1 SPEED.  A/C RETURNED FOR MX.  LT THRUST REVERSER INBOARD UNLOCK SW FOUND SHORTED TO CLOSED POSITION WHICH CAUSED HYD PRESS TO BE SECURED PRIOR TO INBD T/R ACT TRAVELING TO OVERSTOW POSITION.  ALLOWED INBD SIDE OF T/R BUCKETS TO HANG IN AIRSTREAM, AND RETARD LT THROTTLE LVR THRU FEEDBACK CABLE.  MX REPLACED LT T/R INBD STOW SW.  OTBD T/R ACT FOUND LEAKING AND WAS REPLACED.  AN INSPECT OF LT T/R FEEDBACK CABLE ACCOMP WITH NO NOTED DEFECTS.  SYSTEM OPS CHECKS GOOD.  A/C RETURNED TO SERV.
