AN ACR FLC HURRIEDLY DEPARTS THE ACFT DURING A TURN AROUND TO OBTAIN FOOD AND FORGOT TO SHUT DOWN THE #1 ENG.

Narrative

THE CAPT WAS FEELING THE SAME AS ME; HUNGRY AND NOT LOOKING FORWARD TO ANOTHER CREW MEAL. WE PLANNED ON DEPLANING TO PURCHASE FOOD. THE SCHEDULED TIME ON THE GND WAS 1 HR 5 MINS; BUT WE WERE LATE TO THE GATE AND ENDED WITH ONLY 48 MINS. WE KNEW WE DIDN'T HAVE MUCH TIME AND RUSHED THE SHUTDOWN CHKLIST. NORMALLY; THE CHKLIST IS A FO READ/CAPT RESPONDS CHKLIST; BUT TO HASTEN DEPLANING; I READ AND RESPONDED AND MISSED THE FACT THAT THE #1 ENG WAS NOT SHUT DOWN. AS A RESULT; BOTH CAPT AND MYSELF DEPLANED WITH THE #1 ENG STILL RUNNING. I WAS GONE APPROX 4 MINS WHEN SOMEONE SAID AN ENG WAS STILL RUNNING AT OUR GATE. IT TOOK APPROX 1 MIN TO RETURN TO THE COCKPIT. MEANWHILE; A MAINT SUPVR HAD SHUT DOWN THE ENG. BESIDES GREAT EMBARRASSMENT AND RELIEF NO ONE WAS INJURED; I STILL WONDER HOW I COULD HAVE DONE SOMETHING SO DUMB. IT REINFORCES WHAT I ALREADY KNEW: A READ AND RESPOND CHKLIST (2 PERSON) IS TO ENSURE ITEMS ARE COMPLETED. I CAN'T ASSUME SOMEONE WILL PERFORM AN ITEM EVEN THOUGH THEY PERFORMED IT AT THE SAME TIME AND PLACE FOR 20 YRS. WE WERE LUCKY NO ONE WAS INJURED OR ACFT DAMAGED.
