A pitch change actuation system (310) for varying a propeller blade pitch, the pitch change actuation system (310) comprising: an actuator body (340) defining an interior volume (360); a chamber separator (380) located within the interior volume (360) of the actuator body (340) and dividing the interior volume (360) into a first chamber (360a) and a second chamber (360b), the two chambers being fluidly separated by the chamber separator (380). The first and second chambers (360a, 360b) are configured to receive hydraulic fluid. The actuator body (360) is configured to translate relative to the chamber separator (380) in response to a difference in hydraulic pressure between the first chamber (360a) and second chamber (360b); and the translation of the actuator body (340) is configured to effect a change in propeller blade pitch.
