Narrative:

Climbing through FL270 the aircraft yawed to the left and shallowed climb. First officer noticed rollback of #1 instruments and announced 'engine fail.' ECAM then came up with engine #1 stall and the ECAM checklist was followed. PF leveled off at FL270; airspeed was stabilized with the good engine; and an 'emergency' was declared with ATC. Next; we assessed our position and opted for a descent into ZZZ which was 80 NM south; time to descend and run checklists gave us 4-6 alternates; and we chose ZZZ to be the most suitable and familiar. Through further analysis of the engine and event; we concluded that it just rolled back to a sub-idle state with no apparent damage. During descent; multiple restarts were attempted. The first was at FL270 approximately 250 KIAS and APU didn't provide sufficient psi. After waiting a couple mins I tried again and got a start fault; and we then temporarily gave up the restarts to focus on the approach. Continuing with the descent; the flight attendants were briefed and passenger addressed. Later; about 600 ft MSL; we had everything in order and decided to do one more restart -- this one started normal and remained with us through the uneventful landing and taxi to the gate. Crew coordination between pilots and flight attendants was fantastic and all ATC controllers spoon fed us all the assistance we needed.

Title: A319 ENG FAILED DURING CLIMBOUT. INITIAL ATTEMPTS AT RESTART WERE UNSUCCESSFUL. EMER DECLARED AND FLT DIVERTED.

Narrative: CLBING THROUGH FL270 THE ACFT YAWED TO THE L AND SHALLOWED CLB. FO NOTICED ROLLBACK OF #1 INSTS AND ANNOUNCED 'ENG FAIL.' ECAM THEN CAME UP WITH ENG #1 STALL AND THE ECAM CHKLIST WAS FOLLOWED. PF LEVELED OFF AT FL270; AIRSPD WAS STABILIZED WITH THE GOOD ENG; AND AN 'EMER' WAS DECLARED WITH ATC. NEXT; WE ASSESSED OUR POS AND OPTED FOR A DSCNT INTO ZZZ WHICH WAS 80 NM S; TIME TO DSND AND RUN CHKLISTS GAVE US 4-6 ALTERNATES; AND WE CHOSE ZZZ TO BE THE MOST SUITABLE AND FAMILIAR. THROUGH FURTHER ANALYSIS OF THE ENG AND EVENT; WE CONCLUDED THAT IT JUST ROLLED BACK TO A SUB-IDLE STATE WITH NO APPARENT DAMAGE. DURING DSCNT; MULTIPLE RESTARTS WERE ATTEMPTED. THE FIRST WAS AT FL270 APPROX 250 KIAS AND APU DIDN'T PROVIDE SUFFICIENT PSI. AFTER WAITING A COUPLE MINS I TRIED AGAIN AND GOT A START FAULT; AND WE THEN TEMPORARILY GAVE UP THE RESTARTS TO FOCUS ON THE APCH. CONTINUING WITH THE DSCNT; THE FLT ATTENDANTS WERE BRIEFED AND PAX ADDRESSED. LATER; ABOUT 600 FT MSL; WE HAD EVERYTHING IN ORDER AND DECIDED TO DO ONE MORE RESTART -- THIS ONE STARTED NORMAL AND REMAINED WITH US THROUGH THE UNEVENTFUL LNDG AND TAXI TO THE GATE. CREW COORD BTWN PLTS AND FLT ATTENDANTS WAS FANTASTIC AND ALL ATC CTLRS SPOON FED US ALL THE ASSISTANCE WE NEEDED.
