Aircraft
On climb out above 10000 ft and accelerating right wing began oscillating and shaking the aircraft dramatically above 280 knots. We [contacted ATC] and said we would like to return to the airport of departure. Upon slowing the aircraft below 250 knots the oscillation stopped. We burned 2000 lbs of fuel to get to landing weight and landed uneventfully. Right aileron servo had failed.
A320 Captain reported a failure of an aileron servo led to right wing oscillations above 280 knots.
