Narrative:

Normally when taxiing into the gate I shut down the #2 engine to conserve fuel. Our procedures require us to let the engine stabilize for 2 mins prior to shutting down an engine. We had a very short taxi from the runway to our gate. I would have normally shut down the engine on the taxi to the gate, however due to the short taxi, I didn't turn off #2 engine. Once I reached the gate, I did my normal shutdown flow as I would, if I had already shut down #2 engine. I overlooked shutting down the #2 engine in the checklist. We were using the APU for electrical power so everything looked normal. As I did the terminating checklist we switched to the gpu for power. After shutting down the airplane the EFIS was still pwred. This was an abnormal situation which I tried to correct by turning off the gpu power. The EFIS remained illuminated which made me believe we had an electrical problem. I tried to contact our chief pilot for advice on the situation, but was unable to contact him. I asked the station personnel to contact me after they cleaned the aircraft and disconnected the gpu, if the cockpit wasn't dark. The station contacted me, about 5 mins later and advised me that the #2 engine was still running. After the #2 engine was shut down everything was normal in the cockpit. Supplemental information from acn 634436: upon finishing the checklist, I called in the times to operations, grabbed my flashlight, and performed my walkaround inspection. I noticed nothing out of the ordinary and performed the walkaround as I had always done checking for any abnormalities that may have occurred during flight. Also, on my walkaround inspection I will be more attentive to the engine fan blades as they could have cued me into the fact that the #2 engine was still running and not just spinning down after a shutdown.

Title: AN EMB145 AFTER TAXI INTO GATE CREW ACCOMPLISHED NORMAL SHUTDOWN CHK. FO MADE POSTFLT WALKAROUND CHK. LEFT AIRPLANE WITH R ENG OPERATING.

Narrative: NORMALLY WHEN TAXIING INTO THE GATE I SHUT DOWN THE #2 ENG TO CONSERVE FUEL. OUR PROCS REQUIRE US TO LET THE ENG STABILIZE FOR 2 MINS PRIOR TO SHUTTING DOWN AN ENG. WE HAD A VERY SHORT TAXI FROM THE RWY TO OUR GATE. I WOULD HAVE NORMALLY SHUT DOWN THE ENG ON THE TAXI TO THE GATE, HOWEVER DUE TO THE SHORT TAXI, I DIDN'T TURN OFF #2 ENG. ONCE I REACHED THE GATE, I DID MY NORMAL SHUTDOWN FLOW AS I WOULD, IF I HAD ALREADY SHUT DOWN #2 ENG. I OVERLOOKED SHUTTING DOWN THE #2 ENG IN THE CHKLIST. WE WERE USING THE APU FOR ELECTRICAL PWR SO EVERYTHING LOOKED NORMAL. AS I DID THE TERMINATING CHKLIST WE SWITCHED TO THE GPU FOR PWR. AFTER SHUTTING DOWN THE AIRPLANE THE EFIS WAS STILL PWRED. THIS WAS AN ABNORMAL SIT WHICH I TRIED TO CORRECT BY TURNING OFF THE GPU PWR. THE EFIS REMAINED ILLUMINATED WHICH MADE ME BELIEVE WE HAD AN ELECTRICAL PROB. I TRIED TO CONTACT OUR CHIEF PLT FOR ADVICE ON THE SIT, BUT WAS UNABLE TO CONTACT HIM. I ASKED THE STATION PERSONNEL TO CONTACT ME AFTER THEY CLEANED THE ACFT AND DISCONNECTED THE GPU, IF THE COCKPIT WASN'T DARK. THE STATION CONTACTED ME, ABOUT 5 MINS LATER AND ADVISED ME THAT THE #2 ENG WAS STILL RUNNING. AFTER THE #2 ENG WAS SHUT DOWN EVERYTHING WAS NORMAL IN THE COCKPIT. SUPPLEMENTAL INFO FROM ACN 634436: UPON FINISHING THE CHKLIST, I CALLED IN THE TIMES TO OPS, GRABBED MY FLASHLIGHT, AND PERFORMED MY WALKAROUND INSPECTION. I NOTICED NOTHING OUT OF THE ORDINARY AND PERFORMED THE WALKAROUND AS I HAD ALWAYS DONE CHKING FOR ANY ABNORMALITIES THAT MAY HAVE OCCURRED DURING FLT. ALSO, ON MY WALKAROUND INSPECTION I WILL BE MORE ATTENTIVE TO THE ENG FAN BLADES AS THEY COULD HAVE CUED ME INTO THE FACT THAT THE #2 ENG WAS STILL RUNNING AND NOT JUST SPINNING DOWN AFTER A SHUTDOWN.
