## Discrepancy

CREW REPORTED THAT DURING TAKEOFF, THRUST REVERSER UNLOCK LIGHT ILLUMINATED LESS THAN 80 KNOTS. CREW RETURNED TO THE GATE IAW MAINTENANCE PROCEDURE TO LOCK OUT THRUST REVERSER.  CREW ATTEMPTED ANOTHER TAKEOFF AND THE SAME OCCURRENCE OF THE THRUST REVERSER UNLOCK LIGHT INDICATION ILLUMINATED AGAIN LESS THAN 80 KNOTS CAUSING A SECOND REJECTED TAKEOFF.  CREW RETURNED TO THE RAMP WITHOUT ANY FURTHER INCIDENT.
