SAAB 340 DEPARTS MEM WITHOUT PROPER EMER CHKLISTS AND HAS TO RETURN.

Narrative

MEM TO JLN AND WE WERE TO RETURN THE NEXT MORNING. IT WAS SCHEDULED FOR A CONTINUOUS DUTY OVERNIGHT. WE HAD COMPLETED THE EXTERIOR AND INTERIOR PREFLTS INCLUDING ALL OF THE APPROPRIATE CHKLISTS. WE WERE SCHEDULED FOR A ZZ20 DEP. WE WERE ON A ZZ30 MAINT ADVISE TIME TO REPAIR A NAV LIGHT. AT ZZ00 OP PERSONNEL CAME TO OUR ACFT AND ASKED TO BORROW OUR EMER CHKLIST TO COPY IT BECAUSE ANOTHER ACFT WAS MISSING A PAGE IN THEIR CHKLIST. SHE SAID SHE WOULD BRING IT RIGHT BACK. RIGHT AFTER SHE LEFT; A MECH CAME OUT AND FIXED THE LIGHT AND SIGNED US OFF. THE FLT ATTENDANT BROUGHT OUT THE PAX AND THE BAGS WERE ALREADY ON THE ACFT. WITHIN EVERYTHING GOING ON; WE WERE STILL ABLE TO GET THE ACFT OUT ON TIME. WE HAD A VERY SHORT TAXI AND WE WERE AIRBORNE VERY QUICKLY. SHORTLY AFTER TKOF; WE REALIZED OUR OPS STILL HAD OUR EMER CHKLIST. IN THE INTEREST OF SAFETY; WE DECIDED TO RETURN BACK TO THE GATE. WE COORDINATED WITH DISPATCH; OUR OPS AND ATC A RETURN BACK TO THE GATE. ONCE ON THE GND; THE CHKLIST WAS RETURNED TO US. WE REFUELED; THE PAX STAYED ON THE AIRPLANE AND THEN WE WERE REDISPATCHED AND LEFT FOR JLN. THE FLT WAS UNEVENTFUL AND WE WERE APPROX 40 MINS LATE. I BELIEVE THAT THIS PROB COULD BE PREVENTED FROM HAPPENING AGAIN BY 'LOOKING FOR RED FLAGS' THAT WE ARE TAUGHT IN CRM. WE HAD ALREADY COMPLETED OUR CHKLISTS WITH EVERYTHING ON BOARD THEN SOMETHING OUT OF THE ORDINARY HAPPENED WITH SOMEONE BORROWING THE CHKLIST. WE NEED TO GO SLOWER NEXT TIME WE ARE TRYING TO GET THE ACFT OUT ON TIME. WE WERE ALSO DOING OUR THIRD CONTINUOUS DUTY OVERNIGHT IN A ROW AND SINCE IT WAS A FRIDAY NIGHT; OPS DID NOT HAVE ACCESS TO THE CHKLIST SINCE THEY WERE LOCKED UP.
