## Discrepancy

SUDDEN LEFT YAW AND LEFT THROTTLE UN-COMMAND REDUCED TO IDLE. THE LEFT THRUST REVERSER HAD BEEN PREVIOUSLY PLACED ON MEL. CLEARED THE MEL ITEM BY REPLACING THE LH T/R STOW SWITCHES. CYCLED T/R SEVERAL TIMES. T/R OPERATION WAS SMOOTH AND CONSISTENT. ENSURED T/R BUCKETS WERE LOCKED TIGHTLY AND FLUSH WITH COWLING. INSPECTED T/R FEEDBACK CABLE FOR PROPER OPERATION AND ROUTING. NO DEFECTS NOTED.
