COMMUTER LTT DEPARTED WITHOUT REFUELING ON QUICK TURN AROUND.

Narrative

INBOUND TO GEG WE NOTIFIED THE STATION ON COMPANY FREQ THAT WE WOULD REQUIRE FUEL OUTBOUND. DURING OUR 20 MIN TURN ON THE GND NO FUEL TRUCK ARRIVED AND WE WERE DISTRACTED BY THE GND CREW. DURING CLBOUT ON THE OUTBOUND LEG TO SEA WE NOTICED THAT WE ONLY HAD ABOUT 800 LBS OF FUEL ON BOARD -- INSUFFICIENT TO REACH SEA WITH AN ADEQUATE RESERVE. AFTER DISCUSSING THE SIT WE DECIDED TO LAND IN YKM; WA; TO OBTAIN MORE FUEL. ON THE GND THERE; I CALLED OUR FLT FOLLOWER IN SEA AND INFORMED HIM OF WHAT WAS HAPPENING AND HE GAVE US A FLT NUMBER FOR THE OUTBOUND LEG. WE LOADED 800 LBS OF FUEL (WE ALREADY HAD 450 LBS STILL ON BOARD) AND DEPARTED YKM AFTER ABOUT 10 MINS ON THE GND THERE. THE FLT ARRIVED APPROX 20 MINS LATE IN SEA. THE PROB WAS MAINLY DUE TO INATTN ON OUR PART BUT SEVERAL OTHER FACTORS WERE INVOLVED: RECENT EVENTS WITH OUR COMPANY HAD OCCUPIED OUR CONVERSATION INBOUND AND ON THE GND WITH THE GND CREW (THIS STATION IS SLATED TO BE CLOSED SOON). THIS HAD DISTRACTED US AND THE GND CREW (WHO WOULD HAVE BEEN CALLING FOR FUEL) DURING OUR 20 MIN TURN ON THE GND. ALSO THE BEFORE START CHKLIST HAD RECENTLY BEEN CHANGED FROM CHALLENGE AND RESPONSE ('FUEL QUANTITY AND BAL -- CHKED') TO A SINGLE PLT OP PERFORMED BY THE CAPT WHILE THE FO CLOSES THE CABIN DOOR. HAD THE CHKLIST BEEN PERFORMED AS A CHALLENGE AND RESPONSE THE LOW FUEL QUANTITY PROBABLY WOULD HAVE BEEN DETECTED ON THE GND AND THE SIT AVERTED. THIS UNDERSCORES THE IMPORTANCE OF VIGILANCE DURING EVEN THE MOST ROUTINE OPS. IT'S SO EASY TO BECOME COMPLACENT FLYING THE SAME ACFT ON THE SAME RTES OVER AND OVER. ALSO; STRESS FROM EVENTS BEYOND YOUR CTL NEED TO BE LEFT OUTSIDE THE ACFT. SUPPLEMENTAL INFO FROM ACN 276443: AFTER LNDG AND THE PAX HAD DEPARTED; I GOT OUT OF THE PLANE TO MAKE A HEAD CALL. BOTH THE CAPT AND I WERE A LITTLE RUSHED. I SAT BACK UP IN THE COCKPIT WHILE THE CAPT BOARDED THE PAX AND FILLED OUT THE WT AND BAL FORM. I FINISHED WITH THE TKOF DATA WHILE THE CAPT CLBED IN THE COCKPIT AND PROCEEDED WITH THE PRESTART CHKLIST. NEITHER OF US CHKED THE FUEL GAUGE; ASSUMING THAT THE FUEL TRUCK HAD ARRIVED AND GONE WHILE I WAS IN THE HEAD. AS IT WAS; WE COULD HAVE AVOIDED THE INCIDENT ENTIRELY BY TAKING OUR TIME AND THOROUGHLY COVERING ALL ASPECTS OF THE CHKLIST.
