Narrative:

In a nutshell; the conclusion of today's trip into ord could have resulted in serious injury to ground personnel. After parking at gate during night operations; we left the right engine running after the beacon had turned off. This is what happened. Approaching the gate; I called for the right engine to be shut down for final taxi in. This didn't happen; and I didn't notice due to my concentrating on parking the aircraft. Once the brakes were set; we waited several moments for ground power to be hooked up. Once this happened; I called for the left engine to be shut down; and asked for the parking checklist. The second item on the checklist calls for me to respond to engine shutdown; and 'fuel flow zero.' I made this response and we completed the checklist. Perhaps I misread the fuel flow indicator (which probably said 6 for 600 pound fuel flow) to be 0; or I just assumed that the right engine had been shut down; and made the response. When we parked; due to the late arrival of the aircraft; the outbound first officer was waiting to do the walkaround; and asked for the lights -- this at the time we were shutting down engines. There was then a pounding on the side of the aircraft; and a ground call which the first officer (on our flight) tried to answer; but there was no answer. Finally; as we were about to leave our seats and the cockpit; the ground supervisor (I think) came into the cockpit and said that our right engine was still running; and that the beacon had been turned off. He said that his crew had approached the aircraft to begin unloading; but had noticed it. This is submitted because it had the potential to serious hurt a ground crew member during night operations; when a running east might not have been noticed. I am not sure if it was my inattentiveness to the checklist; just being tired from a second straight day of long delays on the same flight; or the distrs from outside the aircraft that caused me to not be fully engaged at the task at hand. This was also the first time that the first officer and I had ever flown together.

Title: 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.
