Procedure; Aircraft
We were operating ZZZ-ZZZ1-ZZZ2 as a through flight; utilizing the same aircraft for both flight segments. Inbound to ZZZ1 we had an ECAM (Electronic Centralized Aircraft Monitoring): Flight Control - Spoiler Fault. The Flight Control System Display showed both #3 spoilers faulted (amber x's). We accomplished the QRH procedure; determined via visual inspection that the spoilers were retracted and consulted with [dispatcher] and [maintenance]. We continued and conducted a normal approach and landing at ZZZ1.Because this same fault had occurred several days earlier; maintenance elected to defer the affected spoilers by de-activating and locking them down. With the aircraft released by maintenance; we departed for ZZZ2.During the climb out we began to notice a slight airframe vibration. I referenced the Flight Control System Display and saw that the right aileron was deflected down and the left deflected upward. There was also a slightly greater than normal amount of rudder displacement.I switched the autopilot off and attempted to trim out the flight controls; but the airplane remained out of trim. There was a check airman on the flight deck conducting a line check; so the captain sent him to the cabin to do a visual inspection of the spoilers. He confirmed that the #3 spoiler on the right wing was partially extended.We again contacted [the Dispatcher] and [Maintenance] and advised them of the situation. The airplane remained fully controllable; and the effect of the raised spoiler on airspeed and fuel burn was negligible. The descent; approach and landing at ZZZ2 were uneventful. When parked at the gate the right #3 spoiler remained in its partially extended position.
A319 First Officer reported experiencing inflight vibration from a partially extended spoiler that was supposed to have been locked down by Maintenance.
