Narrative:

During the approach phase of flight: approximately 10 seconds after landing gear extension; ECAM alert: green hydraulic reservoir low pressure. We executed a go-around; advised ATC that we had a hydraulic problem and needed delay vectors; and then would return for landing. We performed QRH; ECAM actions; and QRH follow up. We made a normal landing on runway X; having advised the flight attendants of our situation; and that we would make a precautionary landing. We advised ATC we were ready to land; and they advised us that crash fire rescue was in position. We were vectored to the localizer runway X; and then cleared for a visual approach. The captain made a smooth landing; and brought the aircraft to a stop on the runway. The emergency crew immediately queried us for our status. We advised that the aircraft was secure; and that we would need a tow to the gate. We received a tow to gate. Maintenance technicians advised us that they found a blown hydraulic fitting on the right main gear door actuator.
