Narrative:

I used jet-a by error. During downwind while switching tanks the engine failed. No problems during the base to final turn, or landing. The fuel location only had 1 cylindrical tank. I initially tried to use the #1 pump which was 100LL octane. The previous user of pump #1 had jammed up the hose while rewinding it electrically on its roller and then gathered up the remainder of the hose and piled it up between pump #1 and pump #2. The hose to the rollers were both identical in color and the #1 hose was hanging off some valves over pump #2. Unknown to me was the fact that the hose was now covering the jet a sign. As a result I fueled my aircraft with jet-a instead of 100LL octane. Callback conversation with reporter revealed the following information: the reporter revealed that, a few days after his experience, signs were installed at the individual fuel counters allowing positive identify of the fuel being pumped.

Narrative: I USED JET-A BY ERROR. DURING DOWNWIND WHILE SWITCHING TANKS THE ENG FAILED. NO PROBS DURING THE BASE TO FINAL TURN, OR LNDG. THE FUEL LOCATION ONLY HAD 1 CYLINDRICAL TANK. I INITIALLY TRIED TO USE THE #1 PUMP WHICH WAS 100LL OCTANE. THE PREVIOUS USER OF PUMP #1 HAD JAMMED UP THE HOSE WHILE REWINDING IT ELECTRICALLY ON ITS ROLLER AND THEN GATHERED UP THE REMAINDER OF THE HOSE AND PILED IT UP BTWN PUMP #1 AND PUMP #2. THE HOSE TO THE ROLLERS WERE BOTH IDENTICAL IN COLOR AND THE #1 HOSE WAS HANGING OFF SOME VALVES OVER PUMP #2. UNKNOWN TO ME WAS THE FACT THAT THE HOSE WAS NOW COVERING THE JET A SIGN. AS A RESULT I FUELED MY ACFT WITH JET-A INSTEAD OF 100LL OCTANE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR REVEALED THAT, A FEW DAYS AFTER HIS EXPERIENCE, SIGNS WERE INSTALLED AT THE INDIVIDUAL FUEL COUNTERS ALLOWING POSITIVE IDENT OF THE FUEL BEING PUMPED.
