Is there anything like test strips that can be used to test for the presence
of jetA?  I never even thought about the potential for jetA to be mistakenly
added to the FBO's fuel tank!  I'd always just made sure that they were
drawing from the 100LL pump.

Mark,

 

<<What color does 100LL turn if you mix in some Jet-A?  Maybe we should add
the "sniff test" to the preflight.  We still take fuel samples as part of
the preflight... right?  >>

 

In the case of contamination where the Avgas is diluted with Jet fuel, it
can slip by completely unnoticed.  The light hue of blue is just slightly
lighter.  I lost my first engine due to Jet fuel contamination.  The FBO was
pumping contaminated fuel for three weeks before folks figured out what was
going on.  The highest concentration of Jet Fuel was 12%.  By the time I got
the bad gas it had been diluted by two more shipments of Avgas plus what
ever was left in my tanks.  My engine was fed something under 5% Jet fuel.
The damage caused by that small amount of contamination caused the insurance
adjuster to opt for all out replacement rather than repair.  180 engines
were damaged.  The engines most sensitive to the contamination were
turbocharged and those with high compression pistons.  There were a few
emergency landings, but no injuries.  It would be interesting to know how
much jet fuel it would take before the average pilot could see or smell the
difference.  One thing is certain.  The engine will notice long before the
pilot.

What impressed me most was how little contamination could be so destructive.
