Narrative:

During flight we had an ECAM come up for the '#1 hp fuel sov' circuit breaker open. We sent an ACARS message to maintenance control advising them of this and asked for their input; but never received a reply. A log entry was made for the popped circuit breaker. During this time; I also checked our flight manual to see if there was any information about this circuit breaker; but could not find any. Upon arrival at the gate; we shut the engines down as we normally do and commenced the parking checklist; but soon found out the #1 engine was still running. Ramp personnel tried to signal me as they didn't understand why the engine was still running. I finally came to the conclusion that maybe the popped circuit breaker was at fault and reset it momentarily at which time the engine shut down. Later; a mechanic chased us down at our next gate to find out how we got the engine to shut down as according to him the hp fuel should have remained open with the circuit breaker open. The point of this report is the fact that I could find no information about the operation of this circuit breaker and what is affected; and upon asking maintenance control for their input; I received no reply. This information would have been very helpful. At the end of the day; I didn't even know if the engine would have shut down if I had pushed the fire switch. On important issues such as this; I feel that maintenance control should have definitely gotten back to me with the information.

Title: AN A320 ENG CONTINUED RUNNING AFTER SHUTDOWN BECAUSE THE HIGH PRESSURE FUEL SHUT-OFF VALVE (HP FUEL SOV) CIRCUIT BREAKER POPPED IN FLT AND VALVE DID NOT CLOSE AT THE GATE.

Narrative: DURING FLT WE HAD AN ECAM COME UP FOR THE '#1 HP FUEL SOV' CIRCUIT BREAKER OPEN. WE SENT AN ACARS MESSAGE TO MAINT CTL ADVISING THEM OF THIS AND ASKED FOR THEIR INPUT; BUT NEVER RECEIVED A REPLY. A LOG ENTRY WAS MADE FOR THE POPPED CIRCUIT BREAKER. DURING THIS TIME; I ALSO CHKED OUR FLT MANUAL TO SEE IF THERE WAS ANY INFO ABOUT THIS CIRCUIT BREAKER; BUT COULD NOT FIND ANY. UPON ARR AT THE GATE; WE SHUT THE ENGS DOWN AS WE NORMALLY DO AND COMMENCED THE PARKING CHKLIST; BUT SOON FOUND OUT THE #1 ENG WAS STILL RUNNING. RAMP PERSONNEL TRIED TO SIGNAL ME AS THEY DIDN'T UNDERSTAND WHY THE ENG WAS STILL RUNNING. I FINALLY CAME TO THE CONCLUSION THAT MAYBE THE POPPED CIRCUIT BREAKER WAS AT FAULT AND RESET IT MOMENTARILY AT WHICH TIME THE ENG SHUT DOWN. LATER; A MECH CHASED US DOWN AT OUR NEXT GATE TO FIND OUT HOW WE GOT THE ENG TO SHUT DOWN AS ACCORDING TO HIM THE HP FUEL SHOULD HAVE REMAINED OPEN WITH THE CIRCUIT BREAKER OPEN. THE POINT OF THIS RPT IS THE FACT THAT I COULD FIND NO INFO ABOUT THE OP OF THIS CIRCUIT BREAKER AND WHAT IS AFFECTED; AND UPON ASKING MAINT CTL FOR THEIR INPUT; I RECEIVED NO REPLY. THIS INFO WOULD HAVE BEEN VERY HELPFUL. AT THE END OF THE DAY; I DIDN'T EVEN KNOW IF THE ENG WOULD HAVE SHUT DOWN IF I HAD PUSHED THE FIRE SWITCH. ON IMPORTANT ISSUES SUCH AS THIS; I FEEL THAT MAINT CTL SHOULD HAVE DEFINITELY GOTTEN BACK TO ME WITH THE INFO.
