Narrative:

After having already experienced 1 emergency landing and overweight landing and maintenance repair, the aircraft was dispatched again to uio. After takeoff, the spoiler EICAS message appeared again, and we again declared an emergency and made an uneventful overweight landing at miami. Aircraft was taken OTS. Callback conversation with reporter revealed the following information: this air carrier flight crew was flying a B757-200 that had had a previous EICAS message related to a spoiler problem and after maintenance had repaired the aircraft the flight crew was attempting their second departure of the day. Again as the aircraft lifted off the EICAS displayed the spoiler malfunction message and the flight crew returned for an overweight landing. This time the flight was canceled until the following day. The mechanics replaced a spoiler actuator and inspected the aircraft in accordance with the overweight landing requirements.
