Narrative:

On climb out the left/G lgciu 1 ECAM displayed (a repeat write-up). We followed the ECAM and turned the ground proximity warning system (GPWS) system off. Soon after that the navigation GPWS fault ECAM appeared. Circuit breakers (circuit breaker) were cycled in accordance with (in accordance with) the QRH. Appropriate [maintenance deficiencies] were submitted. Screens were then cleared. Coming in to [destination]; visual approach backed up with the ILS; I called for gear just prior to glideslope intercept; approximately 1500' AGL. We continued normal configuration to full flaps. Gear indications were left and nose gear indicating down (green lights) and right main indicating not down (red light). We elected to raise the gear; waited until all gear indicated up and locked; and lowered the gear once again; getting the same unsafe indications as before. We executed a go-around approximately 700' MSL and received vectors for an extended downwind and base from ATC. [The] captain got out the QRH for the landing gear not downlocked. Since we had already recycled the gear we elected not to do it again and went to the landing gear gravity extension checklist. Gear came down normally when lowered via the gear extension hand crank. Landing gear handle lowered in accordance with the checklist. Gear indications 3 green lights and 3 green triangles on the sd wheel page. Subsequent approach and landing were uneventful. [The] captain took control of the aircraft on the runway after landing and taxied clear [of the runway] via differential braking and rudder. Aircraft was shut down and towed to the gate. Weather was sky clear; winds 190/7 and unrestricted visibility.

Title: A319 First Officer reported right main gear indicated not down and locked during approach; so the alternate gravity system was used to lower the gear.

Narrative: On climb out the L/G LGCIU 1 ECAM displayed (a repeat write-up). We followed the ECAM and turned the Ground Proximity Warning System (GPWS) system off. Soon after that the NAV GPWS fault ECAM appeared. Circuit Breakers (CB) were cycled In Accordance With (IAW) the QRH. Appropriate [Maintenance deficiencies] were submitted. Screens were then cleared.
