Narrative:

The fuel control switch to cut-off was missed in the shutdown checklist. It was a very early morning flight from lga to dfw. The flight duration was a lot longer due to maintenance problems on pushback and WX rertes around thunderstorms. We were not able to get a timely bathroom break due to security procedures and multiple route changes. Landing and taxi in at dfw were uneventful. Block-in was quick and the checklist items for shutdown were verbalized. Each of us thought the other crew member shut down the last engine with fuel control cut-off switch. The switch was not confirmed off. We both urgently needed a restroom break. As we left the cockpit, the cockpit door was inadvertently shut and locked behind us. We found a flight attendant with a key and we got the door opened. I did not hear the engine running when I left the aircraft. We were contacted by operations and returned to the aircraft and shut down the right engine. Contributing factors were: urgent physiological needs and automatic-locking door with no key in cabin.

Title: ACR FLC LEFT THE R ENG RUNNING AFTER DEPLANING DUE, IN PART, TO THEIR HASTE FOR PHYSIOLOGICAL NEEDS TO USE THE RESTROOM.

Narrative: THE FUEL CTL SWITCH TO CUT-OFF WAS MISSED IN THE SHUTDOWN CHKLIST. IT WAS A VERY EARLY MORNING FLT FROM LGA TO DFW. THE FLT DURATION WAS A LOT LONGER DUE TO MAINT PROBS ON PUSHBACK AND WX RERTES AROUND TSTMS. WE WERE NOT ABLE TO GET A TIMELY BATHROOM BREAK DUE TO SECURITY PROCS AND MULTIPLE RTE CHANGES. LNDG AND TAXI IN AT DFW WERE UNEVENTFUL. BLOCK-IN WAS QUICK AND THE CHKLIST ITEMS FOR SHUTDOWN WERE VERBALIZED. EACH OF US THOUGHT THE OTHER CREW MEMBER SHUT DOWN THE LAST ENG WITH FUEL CTL CUT-OFF SWITCH. THE SWITCH WAS NOT CONFIRMED OFF. WE BOTH URGENTLY NEEDED A RESTROOM BREAK. AS WE LEFT THE COCKPIT, THE COCKPIT DOOR WAS INADVERTENTLY SHUT AND LOCKED BEHIND US. WE FOUND A FLT ATTENDANT WITH A KEY AND WE GOT THE DOOR OPENED. I DID NOT HEAR THE ENG RUNNING WHEN I LEFT THE ACFT. WE WERE CONTACTED BY OPS AND RETURNED TO THE ACFT AND SHUT DOWN THE R ENG. CONTRIBUTING FACTORS WERE: URGENT PHYSIOLOGICAL NEEDS AND AUTO-LOCKING DOOR WITH NO KEY IN CABIN.
