B757-200 FLT CREW FORGOT TO SHUT DOWN THE R ENG.

Narrative

IN A NUTSHELL; THE CONCLUSION OF TODAY'S TRIP INTO ORD COULD HAVE RESULTED IN SERIOUS INJURY TO GND PERSONNEL. AFTER PARKING AT GATE DURING NIGHT OPS; WE LEFT THE R ENG RUNNING AFTER THE BEACON HAD TURNED OFF. THIS IS WHAT HAPPENED. APCHING THE GATE; I CALLED FOR THE R ENG TO BE SHUT DOWN FOR FINAL TAXI IN. THIS DIDN'T HAPPEN; AND I DIDN'T NOTICE DUE TO MY CONCENTRATING ON PARKING THE ACFT. ONCE THE BRAKES WERE SET; WE WAITED SEVERAL MOMENTS FOR GND PWR TO BE HOOKED UP. ONCE THIS HAPPENED; I CALLED FOR THE L ENG TO BE SHUT DOWN; AND ASKED FOR THE PARKING CHKLIST. THE SECOND ITEM ON THE CHKLIST CALLS FOR ME TO RESPOND TO ENG SHUTDOWN; AND 'FUEL FLOW ZERO.' I MADE THIS RESPONSE AND WE COMPLETED THE CHKLIST. PERHAPS I MISREAD THE FUEL FLOW INDICATOR (WHICH PROBABLY SAID 6 FOR 600 LB FUEL FLOW) TO BE 0; OR I JUST ASSUMED THAT THE R ENG HAD BEEN SHUT DOWN; AND MADE THE RESPONSE. WHEN WE PARKED; DUE TO THE LATE ARR OF THE ACFT; THE OUTBOUND FO WAS WAITING TO DO THE WALKAROUND; AND ASKED FOR THE LIGHTS -- THIS AT THE TIME WE WERE SHUTTING DOWN ENGS. THERE WAS THEN A POUNDING ON THE SIDE OF THE ACFT; AND A GND CALL WHICH THE FO (ON OUR FLT) TRIED TO ANSWER; BUT THERE WAS NO ANSWER. FINALLY; AS WE WERE ABOUT TO LEAVE OUR SEATS AND THE COCKPIT; THE GND SUPVR (I THINK) CAME INTO THE COCKPIT AND SAID THAT OUR R ENG WAS STILL RUNNING; AND THAT THE BEACON HAD BEEN TURNED OFF. HE SAID THAT HIS CREW HAD APCHED THE ACFT TO BEGIN UNLOADING; BUT HAD NOTICED IT. THIS IS SUBMITTED BECAUSE IT HAD THE POTENTIAL TO SERIOUS HURT A GND CREW MEMBER DURING NIGHT OPS; WHEN A RUNNING E MIGHT NOT HAVE BEEN NOTICED. I AM NOT SURE IF IT WAS MY INATTENTIVENESS TO THE CHKLIST; JUST BEING TIRED FROM A SECOND STRAIGHT DAY OF LONG DELAYS ON THE SAME FLT; OR THE DISTRS FROM OUTSIDE THE ACFT THAT CAUSED ME TO NOT BE FULLY ENGAGED AT THE TASK AT HAND. THIS WAS ALSO THE FIRST TIME THAT THE FO AND I HAD EVER FLOWN TOGETHER.
