Narrative:

Aircraft was refueled with 100 gallons jet with prist. Was left outside due to no hangar space available. Overnight outside air temperature was +10 des F. Aircraft was preflted and both engines started to warm up cabin and engine's oil. Engines ran for 15-20 mins. We then loaded passenger and began to taxi out for departure. During taxi; r-hand engine failed. We then taxied back to hangar. Maintenance determined that the fuel was not contaminated and both engine fuel filters were clean. Further testing of the fuel revealed a higher than normal concentration of prist additive. Normal levels are .10 to .15 parts per million. Our fuel tested .21 parts per million. All tanks were drained; new fuel loaded into plane. Advised the last 4 FBO's where we purchased fuel of the problem. 3 of them tested their fuel immediately. Still awaiting report from the last FBO we were at.

Title: C560 EXPERIENCES ENG FAILURE ON TAXI OUT DURING COLD WX OPS. INSPECTION INDICATES AN EXCESSIVE LEVEL OF ANTI-ICING ADDITIVE IN FUEL.

Narrative: ACFT WAS REFUELED WITH 100 GALLONS JET WITH PRIST. WAS LEFT OUTSIDE DUE TO NO HANGAR SPACE AVAILABLE. OVERNIGHT OUTSIDE AIR TEMP WAS +10 DES F. ACFT WAS PREFLTED AND BOTH ENGS STARTED TO WARM UP CABIN AND ENG'S OIL. ENGS RAN FOR 15-20 MINS. WE THEN LOADED PAX AND BEGAN TO TAXI OUT FOR DEP. DURING TAXI; R-HAND ENG FAILED. WE THEN TAXIED BACK TO HANGAR. MAINT DETERMINED THAT THE FUEL WAS NOT CONTAMINATED AND BOTH ENG FUEL FILTERS WERE CLEAN. FURTHER TESTING OF THE FUEL REVEALED A HIGHER THAN NORMAL CONCENTRATION OF PRIST ADDITIVE. NORMAL LEVELS ARE .10 TO .15 PARTS PER MILLION. OUR FUEL TESTED .21 PARTS PER MILLION. ALL TANKS WERE DRAINED; NEW FUEL LOADED INTO PLANE. ADVISED THE LAST 4 FBO'S WHERE WE PURCHASED FUEL OF THE PROB. 3 OF THEM TESTED THEIR FUEL IMMEDIATELY. STILL AWAITING RPT FROM THE LAST FBO WE WERE AT.
