During approach to land at approximately 30 to 50 feet; I initiated a go around due to a wind gust that destabilized my approach. After advancing the thrust levers to TOGA and calling out go around thrust; flaps 3; we heard a loud pop; followed by a roll to the right in addition to the right roll that I was already correcting for the gust. At that time I believed we had broken a flap because of the single pop and roll. I again called for flaps 3 since the pop noise was a distraction. With positive rate we brought up the gear and proceeded straight out. The climb performance was poor so I again asked if we were flaps 3 without looking at the indication because I was concentrating on the flight directors and speed due to the poor climb performance. At some point in the climb we notified ATC we were electing to do the single engine out departure procedure due to poor performance and so that we could turn into the good engine. Turbulence contributed to the poor performance but we still felt something was off. At around 2000MSL I decided we would level at 2200MSL instead of 2400MSL due to the long period of time our remaining engine was at TOGA and our poor climb performance. Once clean we climbed to around 2600 to 2800MSL before turning for some cushion on altitude. At 3000MSL I engaged the autopilot which was not really available prior due to airspeed below VLS on numerous occasions. At that point I called for ECAM actions. We secured the #2 engine and discharged the one fire bottle due to engine damage. We conducted the single engine approach checklist. By this time we were past abeam the numbers for the visual so any delay would extend flight longer than needed. Once we were comfortable that we could land safely we turned base for the approach. We landed and pulled off the runway in a position that would allow fire/rescue to examine the #2 engine before taxi to the gate.
Upon inspection the #2 engine had seized and had significant damage to the N2 portion or the engine.
A319 flight crew reported the #2 engine failed during a go-around from an unstabilized approach. Crew reported the aircraft performed poorly in the single-engine climb.
