AN EMBRAER 145 AT TRIP TERMINATION AND AFTER COMPLETING PARKING CHKLIST THE FLC FAILED OT SHUT DOWN THE R ENG.

Narrative

AFTER PARKING; CAPT ASKED FOR 'PARKING CHKLIST.' FIRST 2 ITEMS ARE FO RESPONSE THEN IS ALL CAPT RESPONSE. I READ CHKLISTS WHILE HE WAS RESPONDING. ENDED THE CHKLISTS HE TOOK HIS EQUIP AND LEFT THE COCKPIT. I STAYED TO FINISH MY DUTIES AND THEN DO MY POST-FLT INSPECTION. I WAS GOING TO START POST INSPECTION WHEN RAMP PERSONNEL ASKED ME WHY THEY COULD NOT GET PWR TO SVC THE LAVATORY FLUID. I WENT BACK IN THE COCKPIT TO SEE IF SOMETHING WAS WRONG. I WAS LOOKING AT THE OVERHEAD PANEL WHEN MAINT PERSONNEL WALKED IN THE COCKPIT AND ASKED WHY #2 ENG WAS STILL RUNNING. I LOOKED AT THE START/STOP SELECTOR AND IT WAS IN 'RUN' POS INSTEAD OF 'STOP.' I PROCEEDED TO SHUT #2 ENG DOWN. I DO NOT KNOW HOW THE CAPT MISSED IT BUT WE READ THE CHKLIST COMPLETELY. I AM SURE THAT THIS SAFETY INCIDENT COULD HAVE BEEN AVOIDED IF IN THE CHKLIST THIS CRITICAL ITEM WILL BE A DOUBLE RESPONSE (CAPT AND FO). THIS WAY BOTH OF US HAVE TO ENSURE ENG IS SHUT DOWN AND SECURED. THIS INCIDENT HAPPENED BEFORE IN MY COMPANY AND NOTHING HAS BEEN DONE TO IMPROVE COMPLIANCE WITH CHKLIST. ANOTHER REASON FOR THIS OVERLOOK IS THAT THE 2 'START/STOP SELECTORS' WE USE TO SHUT DOWN ENGS ARE COVERED BY A STRIPED PLASTIC COVER (USED TO AVOID INADVERTENT SELECTION). THIS COVER HIDES THE SWITCHES MAKING IT HARD TO SEE THE SELECTORS POS.
