FLC OF AN LTT DIVERTED TO AN ALTERNATE AFTER THE LOW FUEL WARNING LIGHTS CAME ON DURING CLB.

Narrative

I FLEW ACFT IN QUESTION ON PREVIOUS AFTERNOON SHIFT (NOV/XX/94). THE CAPT AND I DETERMINED THAT THE WRONG FUEL GAUGE HAD BEEN WRITTEN UP AS INOP PREVIOUSLY THAT DAY. CAPT THAT FLEW MORNING SHIFT ON NOV/XX/94 SAID R FUEL GAUGE WAS INACCURATE. WHEN ACFT WAS FUELED PER MEL INSTRUCTIONS; I NOTICED THAT THE L FUEL GAUGE INDICATED APPROX 1850 LBS OF FUEL AND R GAUGE INDICATED 1600 LBS. SINCE FULL TANK ONLY HOLDS 1600 LBS IT WAS DETERMINED THAT THE R SIDE GAUGE WAS ACCURATE AND WAS MISTAKENLY WRITTEN UP; WHEN INDEED IT WORKED FINE. UPON REVIEW OF COMPANY OPS MANUAL AND COMPANY FLT MANUAL; IT WAS DETERMINED THAT THE WRITE UP COULD ONLY BE CLRED BY THE ORIGINATING CAPT. UPON ARRIVING AT OUR DOMICILE; THE CAPT NOTIFIED MAINT CTL THAT THE WRONG FUEL GAUGE HAD BEEN WRITTEN UP. THE CAPT ALSO LEFT A NOTE IN THE CAPT'S BOX WHO WROTE UP THE R SIDE FUEL GAUGE. THE CAPT WHO WROTE UP THE FUEL GAUGE WAS FLYING ON THE MORNING OF NOV/XX/04. HE DID NOT CORRECT WRITE UP NOR HAD MAINT CORRECTED IT. THE CAPT THAT I FLEW WITH ON NOV/XX/04 LOOKED OVER THE DISCREPANCIES PRIOR TO FLT AND SAW THAT THE R FUEL GAUGE WAS MEL'ED. HE ASSUMED THAT THE L GAUGE WAS ACCURATE IT READ APPROX 800 LBS; THE R GAUGE READ APPROX 500 LBS. I DID NOT GET TO GO OVER THE WRITE UPS WITH THE CAPT; BECAUSE I JUST ASSUMED IT WAS TAKEN CARE OF. I ASKED THE CAPT WHO ORIGINATED THE WRITE UP IF HE GOT OUR NOTE FROM THE PREVIOUS NIGHT AND HE SAID HE STILL THOUGHT THE R GAUGE DID NOT WORK. UPON CLBOUT; APPROX 9 MI FROM MTJ; I NOTICED BOTH FUEL QUANTITY ANNUNCIATORS WERE ILLUMINATED. I CALLED IT TO THE CAPT'S ATTN AND SUGGESTED WE RETURN TO MTJ. FUEL QUANTITY ANNUNCIATORS ILLUMINATED INDICATE APPROX 650 LBS OF FUEL REMAINING. CAPT SUGGESTED I LEVEL ACFT; I DID; AND ANNUNCIATORS EXTINGUISHED. WE RESUMED CLB; AND ANNUNCIATORS ILLUMINATED AGAIN. WE DECIDED TO MAKE A PRECAUTIONARY LNDG IN GUNNISON; CO; TO GET FUEL. AFTER FUELING WE PROCEEDED TO DENVER; OUR DEST. THIS WHOLE SIT WAS A COMPLETE MESS; AND I SHOULD HAVE BEEN MORE ALERT AND ON TOP OF THINGS WHEN ACFT WAS PICKED UP UPON START OF SHIFT. THE FIRST TIME I LOOKED AT THE FUEL GAUGES WAS DURING CLB AFTER I SAW THE FUEL QUANTITY ANNUNCIATORS. ALTHOUGH THE ORIGINAL 1000 LBS WOULD HAVE BEEN ENOUGH TO GET TO DENVER; IT WOULD NOT BE LEGAL FUEL. THE CAPT THAT I FLEW WITH THE PREVIOUS EVENING SHOULD HAVE GROUNDED THE ACFT; AND THIS WHOLE EVENT WOULD HAVE BEEN AVOIDED; AND I SHOULD HAVE INSISTED IT BE DONE.
