Narrative:
On arrival into phoenix, at flight level 350, approximately 160 degrees NM northeast of phx on the buntr arrival, we got an ECAM caution engine 2 compressor vane. The ECAM advised us to avoid thrust changes. We had been cleared to descend to FL290, so not changing thrust was certainly not an option, and yet the ECAM did not specifically tell us to shut it down. We did a gradual descent down to FL290. As we leveled off, the engine #2 N2 went up to about 99%, and the egt fluctuated, but the engine seemed to stabilize about even with #1 engine. We continued on for a couple of more mins, keeping a constant eye on the engine parameters, when suddenly the egt spiked, the N2 went up above 100%+, and after a couple of bumps, which I suspect were compressor stalls, the engine stalled completely. At that point, we followed the ECAM procedures, which included the engine shut down procedure. Considering that there had been no fire, and that none was indicated, the decision was made to not use the fire extinguishers. We also decided that because of the way the engine shutdown and the unstable parameters indicated prior to shutdown, restarting the engine, at least at this point, was probably not a good idea. We called maintenance and dispatch, and advised them that we would be coming home on 1 engine. We then briefed the flight attendants that we would be making a precautionary landing in phoenix in about 20 mins. After talking to the passenger, we reviewed everything we had done up to this point, and satisfied that we had done all that we could with the engine, we prepared for a single engine landing. The first officer briefed the visual approach, and we set the aircraft up for a flaps 3 landing, using medium autobrake. A normal approach profile and landing was made to runway 26 in phx. Passenger were advised that the situation was under control, and that we would be taxiing to the gate. Brake temperatures were monitored, and brake fans were turned on as we taxied to the gate, where we shut the aircraft down and handed it over to maintenance. Passenger were deplaned through the jetway, and crew members were debriefed, and we all went on our way.

Title: A320 CREW HAD #2 ENG FAILURE NEAR PHX.
Narrative: ON ARR INTO PHOENIX, AT FLT LEVEL 350, APPROX 160 DEGS NM NE OF PHX ON THE BUNTR ARR, WE GOT AN ECAM CAUTION ENG 2 COMPRESSOR VANE. THE ECAM ADVISED US TO AVOID THRUST CHANGES. WE HAD BEEN CLRED TO DSND TO FL290, SO NOT CHANGING THRUST WAS CERTAINLY NOT AN OPTION, AND YET THE ECAM DID NOT SPECIFICALLY TELL US TO SHUT IT DOWN. WE DID A GRADUAL DSCNT DOWN TO FL290. AS WE LEVELED OFF, THE ENG #2 N2 WENT UP TO ABOUT 99%, AND THE EGT FLUCTUATED, BUT THE ENG SEEMED TO STABILIZE ABOUT EVEN WITH #1 ENG. WE CONTINUED ON FOR A COUPLE OF MORE MINS, KEEPING A CONSTANT EYE ON THE ENG PARAMETERS, WHEN SUDDENLY THE EGT SPIKED, THE N2 WENT UP ABOVE 100%+, AND AFTER A COUPLE OF BUMPS, WHICH I SUSPECT WERE COMPRESSOR STALLS, THE ENG STALLED COMPLETELY. AT THAT POINT, WE FOLLOWED THE ECAM PROCS, WHICH INCLUDED THE ENG SHUT DOWN PROC. CONSIDERING THAT THERE HAD BEEN NO FIRE, AND THAT NONE WAS INDICATED, THE DECISION WAS MADE TO NOT USE THE FIRE EXTINGUISHERS. WE ALSO DECIDED THAT BECAUSE OF THE WAY THE ENG SHUTDOWN AND THE UNSTABLE PARAMETERS INDICATED PRIOR TO SHUTDOWN, RESTARTING THE ENG, AT LEAST AT THIS POINT, WAS PROBABLY NOT A GOOD IDEA. WE CALLED MAINT AND DISPATCH, AND ADVISED THEM THAT WE WOULD BE COMING HOME ON 1 ENG. WE THEN BRIEFED THE FLT ATTENDANTS THAT WE WOULD BE MAKING A PRECAUTIONARY LNDG IN PHOENIX IN ABOUT 20 MINS. AFTER TALKING TO THE PAX, WE REVIEWED EVERYTHING WE HAD DONE UP TO THIS POINT, AND SATISFIED THAT WE HAD DONE ALL THAT WE COULD WITH THE ENG, WE PREPARED FOR A SINGLE ENG LNDG. THE FO BRIEFED THE VISUAL APCH, AND WE SET THE ACFT UP FOR A FLAPS 3 LNDG, USING MEDIUM AUTOBRAKE. A NORMAL APCH PROFILE AND LNDG WAS MADE TO RWY 26 IN PHX. PAX WERE ADVISED THAT THE SIT WAS UNDER CTL, AND THAT WE WOULD BE TAXIING TO THE GATE. BRAKE TEMPS WERE MONITORED, AND BRAKE FANS WERE TURNED ON AS WE TAXIED TO THE GATE, WHERE WE SHUT THE ACFT DOWN AND HANDED IT OVER TO MAINT. PAX WERE DEPLANED THROUGH THE JETWAY, AND CREW MEMBERS WERE DEBRIEFED, AND WE ALL WENT ON OUR WAY.
