A DHC6 FLC DEPARTED WITH LESS THAN DISPATCH FUEL AND HAD TO DIVERT TO AN ENRTE ALTERNATE.

Narrative

WE HAD A 1 1/2 HR BREAK AND DECIDED TO GO BACK TO THE FBO TO EAT DINNER. THE CAPT LEFT A FUEL REQUEST FOR OUR NEXT FLT TO HOMER; AK; FOR 1600 LBS OF FUEL TO THE RAMP AGENTS BEFORE WE LEFT. WHEN WE RETURNED; I WENT INTO THE TERMINAL AND COMPLETED THE WT AND BAL. I RETURNED TO THE ACFT AND GAVE THE SAFETY BRIEFING TO THE PAX. AFTER COMPLETING THE BRIEFING; THE CAPT ASKED IF IT WAS 'CLR R' AND I RESPONDED 'CLR R' AS HE BEGAN STARTER ROTATION ON THE R ENG. AFTER STARTING THE ENGS; WE PERFORMED THE 'AFTER START' AND 'BEFORE TKOF' CHKLISTS AS WE TAXIED OUT TO THE RWY. IT WAS MY LEG; SO I TOOK THE CTLS AS WE TAXIED ONTO THE RWY. WE DEPARTED THE ARPT AND USED A R-HAND DOWNWIND DEP AS INSTRUCTED BY TWR. ABOUT 5 MINS LATER; THE CAPT CALLED IN OUR OUT/OFF TIMES AND FUEL ON BOARD TO DISCOVER THAT WE ONLY HAD ABOUT 700-720 LBS OF FUEL ON BOARD AT THAT INSTANT IN TIME. OUR MINIMUM DISPATCH FUEL TO HOMER WAS 950 LBS. ANCHORAGE WAS DEALING WITH AN EMER DUE TO A B737 THAT WAS HAVING GEAR PROBS; SO WE DECIDED TO DIVERT TO KENAI FOR FUEL. THE MINIMUM DISPATCH FUEL TO KENAI WAS 750 LBS THAT DAY; WHICH WE CALCULATED WE HAD PRIOR TO TKOF. WE NOTIFIED THE DISPATCHER OF OUR INTENTIONS AND WERE RERELEASED TO HOMER VIA KENAI. WE LANDED IN KENAI AND RECEIVED OUR NEW RELEASE AND FUEL; INFORMED THE PAX OF THE SIT; AND CONTINUED TO HOMER. ONCE WE RETURNED TO ANCHORAGE; WE WERE RELIEVED OF DUTY AND THE NEXT DAY WE WERE BOTH GIVEN A WK OFF WITHOUT PAY. THE FACTORS THAT CONTRIBUTED TO THIS SIT ARE THE FACT THAT WE DIVERTED FROM SOP'S. I WAS PREVIOUSLY INSTRUCTED BY THE PIC THAT HE WOULD COMPLETE THE 'BEFORE START' CHKLIST TO HIMSELF WHILE I COMPUTE THE WT AND BAL OR BRIEF THE PAX IN ORDER TO EXPEDITE ACTIVITY. THE BEFORE START CHKLIST IS A CREW CHKLIST AND SHOULD BE COMPLETED BY THE CAPT AND FO SIMULTANEOUSLY. THE SECOND FACTOR; WHICH MAY HAVE CONTRIBUTED TO THE PROB OCCURRED DURING COMPLETING THE WT AND BAL. I HAD BEEN USING THE FUEL INDICATED ON THE RELEASE AND REQUESTED BY THE CAPT; AS DO MOST FO'S AT THIS COMPANY. SINCE WE ARE OFTEN WT LIMITED AND WE USE ACTUAL PAX WTS; THE FO USUALLY STAYS INSIDE WITH THE GATE AGENT TO LET HIM/HER KNOW HOW MANY PAX WE CAN TAKE; BASED ON THE FUEL INDICATED BY THE CAPT PER OUR RELEASE. WE MAKE THE ASSUMPTION THAT THE RAMP WILL PUT ON THE PROPER AMOUNT OF FUEL. THIS PROB COULD HAVE BEEN PREVENTED BY FOLLOWING SOP'S. ONCE THE PROB WAS DISCOVERED; IT IS MY BELIEF THAT WE PERFORMED THE PROPER CORRECTIVE ACTIONS TO RESOLVE OUR MISTAKE. IT WAS OUT INTENT NOT TO COMPLICATE MATTERS OR JEOPARDIZE SAFETY; SO THE CAPT MADE THE DECISION TO DIVERT TO KENAI. THE STOP IN KENAI FOR FUEL DELAYED OUR ARR IN HOMER BY 12 MINS. I FEEL THE TIME LOST IS INSIGNIFICANT TO THE ADDED SAFETY THAT WAS GAINED BY STOPPING FOR FUEL. SOME HUMAN PERFORMANCE CONSIDERATIONS INCLUDE THE FACT THAT BOTH OF US HAD VERY LITTLE EXPERIENCE FOR THE SIT WE WERE IN. THE CAPT ONLY HAD ABOUT 100 HRS OF PIC TIME IN THE ACFT AND APPROX 1000 HRS OF SIC TIME IN THE ACFT. I ONLY HAD ABOUT 50 HRS OF SIC TIME IN THE ACFT. THE OTHER HUMAN FACTOR THAT CONTRIBUTED TO THIS PROB WAS REPETITION. WE HAD BEEN FLYING TOGETHER THE LAST 3-4 DAYS DOING THE EXACT SAME LINES AND HAD BUILT THE ROUTINE THAT THE CAPT WOULD PERFORM THE 'BEFORE START' CHKLIST WHICH HAS A CALL FOR 'FUEL QUANTITY/SYS -- CHKED/NORMAL -- (CAPT'S RESPONSE).' TO REMEDY FURTHER SITS; I WILL ALWAYS QUESTION THE CAPT'S AUTH TO DEVIATE FROM SOP. I AM ALSO WORKING WITH OUR DIRECTOR OF OPS ON PROMOTING THE USE AND IMPORTANCE OF CHKLISTS. FINALLY; IT IS MY GOAL TO REVIEW THE WT AND BAL PROCS AND TRY TO ESTABLISH A PROC THAT WILL ALLOW EFFICIENCY AND ACCURACY.
