ENG INFLT SHUTDOWN CREATED BY ACFT FUEL EQUIP PROBLEM.

Narrative

APPROX 15 MINS INTO FLT AND LEVEL AT 14000 FT. WE BEGAN TO GET VERY ERRATIC PWR SURGES FROM THE R ENG. ALL ENG INSTS WERE INDICATING NORMAL EXCEPT FOR THE EGT GAUGE WHICH BEGAN TO RAISE RAPIDLY DUE TO THE ABNORMAL PWR SURGES. PWR IN THE R ENG DROPPED TO IDLE AND WE BEGAN SINGLE ENG CHKLIST AND SHUTDOWN PROC AND AT THE SAME TIME DECIDED TO DIVERT TO COLUMBIA ARPT SINCE THIS WAS THE CLOSEST ARPT. AS WE WERE ABOUT TO SHUT DOWN R ENG WE BEGAN TO GET NORMAL PWR BACK. AS WE CONTINUED TO COLUMBIA I FLEW THE AIRPLANE AND MY FO WOULD HANDLE SHUT DOWN PROCS ON ENG IF NECESSARY. WE WERE THEN VECTORED BY COLUMBIA APCH TO LNDG AND ABOUT 2 MI OUT ON FINAL THE R ENG QUIT AGAIN AS FO BEGAN SHUT DOWN PROC THE PWR STARTED UP AGAIN THEREFORE THE ENG WAS NEVER FEATHERED. AS WE BEGAN THE LNDG THE L ENG CUT OFF AND WE HAD TO BE TOWED INTO THE FBO AT ARPT OF LNDG. I THEN WENT TO THE FAA AND FILED A RPT AND WE CONTACTED 0A6 AND ADVISED THEM NOT TO ALLOW ANY DEPS OF ACFT THAT MAY HAVE BEEN FUELED BY THE SAME TRUCK WE WERE FUELED WITH. AFTER LNDG WE CHKED THE FUEL SUMPS AND FOUND WATER AND SEDIMENT IN THE SAMPLE. WE HAD DRAINED ALL THE FUEL SUMPS ON THE ACFT DURING PREFLT. AFTER FURTHER INSPECTION BY THE MECHS IN COLUMBIA THEY FOUND APPROX 15 - 17 OUNCES OF WATER IN THE FUEL LINES AND PUMPS. I BELIEVE THE PROBLEM AROSE FROM RECEIVING CONTAMINATED FUEL IN GASTONIA; NC; 0A6. I DON'T BELIEVE THE FUEL TRUCK SUMPS WERE DRAINED. SUPPLEMENTAL INFO FROM ACN 200520. I BELIEVE THE PROBLEM AROSE AT GASTONIA WHEN WE GOT 60 GALS OF FUEL WITH WATER. I DO NOT BELIEVE THE FUEL TRUCK'S SUMPS WERE DRAINED. OUR PLANE WAS HANGARED AND THE SUMPS WERE DRAINED BEFORE BEING FUELED.
