Narrative:
Approaching OM (orchy) on ILS runway 22 at lga, first officer flying, slowing through 150 KTS, selected gear down, flaps 3 degrees, engine #1 flamed out. Accomplished ECAM, started APU (WX 300 ft and 6000 ft RVR), attempted relight. Relight occurred by 400 ft AGL. Uneventful landing. Engine overtemped at flameout. Emergency was declared with tower at flameout. Callback conversation with reporter revealed the following information: the reporter stated the engine was an iae V2500 and the flameout was caused by the low pressure pneumatic bleed check valve failing in the open position. The reporter said when the high stage pneumatic valve opened the air was bled into the low stage compressor section causing the flameout.

Title: AN AIRBUS A320 ON APCH AT 2000 FT DECLARED AN EMER DUE TO #1 ENG FLAMEOUT CAUSED BY A FAILED LOW PRESSURE PNEUMATIC BLEED CHK VALVE.
Narrative: APCHING OM (ORCHY) ON ILS RWY 22 AT LGA, FO FLYING, SLOWING THROUGH 150 KTS, SELECTED GEAR DOWN, FLAPS 3 DEGS, ENG #1 FLAMED OUT. ACCOMPLISHED ECAM, STARTED APU (WX 300 FT AND 6000 FT RVR), ATTEMPTED RELIGHT. RELIGHT OCCURRED BY 400 FT AGL. UNEVENTFUL LNDG. ENG OVERTEMPED AT FLAMEOUT. EMER WAS DECLARED WITH TWR AT FLAMEOUT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ENG WAS AN IAE V2500 AND THE FLAMEOUT WAS CAUSED BY THE LOW PRESSURE PNEUMATIC BLEED CHK VALVE FAILING IN THE OPEN POS. THE RPTR SAID WHEN THE HIGH STAGE PNEUMATIC VALVE OPENED THE AIR WAS BLED INTO THE LOW STAGE COMPRESSOR SECTION CAUSING THE FLAMEOUT.
