Narrative:

The ship's APU was inoperative, requiring the aircraft to be parked at a jetway with ground power. Once at the gate the left engine was shut down while the right engine was still running so as to provide power until the ground power could be hooked up. In the process of completing this, we opened the cockpit door to inform the flight attendant to open the main cabin door so the jetway could be moved into place and ground power hooked up. During this process, the passenger were all standing and crowding towards the door and the flight attendant who was waiting for the walkway to be secured and maintain control of an unaccompanied minor at the same time. In an attempt to help the flight attendant we called the minor into the cockpit. During this time we were still waiting for ground power to be hooked up. At this time I thought the checklist was done once power was installed and power was xferred. However, the right engine was still running. I discovered the engine still running during the postflt walkaround and subsequently secured the engine. I also found the beacon on, and the nose landing gear steering on. I believe this situation might have been avoided if the cockpit door would have remained closed until the shutdown checklist was completed and the captain was not trying to catch a flight home.

Title: CL65 CREW FAILS TO COMPLETE PARKING CHKLIST. ENG IS LEFT RUNNING UNTIL DISCOVERED ON PREFLT FOR NEXT FLT.

Narrative: THE SHIP'S APU WAS INOP, REQUIRING THE ACFT TO BE PARKED AT A JETWAY WITH GND PWR. ONCE AT THE GATE THE L ENG WAS SHUT DOWN WHILE THE R ENG WAS STILL RUNNING SO AS TO PROVIDE PWR UNTIL THE GND PWR COULD BE HOOKED UP. IN THE PROCESS OF COMPLETING THIS, WE OPENED THE COCKPIT DOOR TO INFORM THE FLT ATTENDANT TO OPEN THE MAIN CABIN DOOR SO THE JETWAY COULD BE MOVED INTO PLACE AND GND PWR HOOKED UP. DURING THIS PROCESS, THE PAX WERE ALL STANDING AND CROWDING TOWARDS THE DOOR AND THE FLT ATTENDANT WHO WAS WAITING FOR THE WALKWAY TO BE SECURED AND MAINTAIN CTL OF AN UNACCOMPANIED MINOR AT THE SAME TIME. IN AN ATTEMPT TO HELP THE FLT ATTENDANT WE CALLED THE MINOR INTO THE COCKPIT. DURING THIS TIME WE WERE STILL WAITING FOR GND PWR TO BE HOOKED UP. AT THIS TIME I THOUGHT THE CHKLIST WAS DONE ONCE PWR WAS INSTALLED AND PWR WAS XFERRED. HOWEVER, THE R ENG WAS STILL RUNNING. I DISCOVERED THE ENG STILL RUNNING DURING THE POSTFLT WALKAROUND AND SUBSEQUENTLY SECURED THE ENG. I ALSO FOUND THE BEACON ON, AND THE NOSE LNDG GEAR STEERING ON. I BELIEVE THIS SIT MIGHT HAVE BEEN AVOIDED IF THE COCKPIT DOOR WOULD HAVE REMAINED CLOSED UNTIL THE SHUTDOWN CHKLIST WAS COMPLETED AND THE CAPT WAS NOT TRYING TO CATCH A FLT HOME.
