Re: X Air Hawk fuel tank 'shedding' particles into fuel
Agreed, it is nothing to do with the engine it is to do with
fibreglass, vinyl ester resins, epoxy resins and their weaknesses to
current aviation and/or car fuels.
This issue is simply, fuels or additives in fuels leach into the
resins and dissolve them therefore leaving exposed fibres from the
fibreglass which eventually get broken off from the fuel sloshing
around and then they end up in the fuel lines and the fuel filters
eventually causing fuel supply issues, engine stoppages etc.
It is only the bottom end of aviation that uses fibreglass fuel
tanks, every other industry knows their weaknesses and has moved on
to other products. Most cars 25 years ago used steal for their fuel
tanks but almost unanimously they have all now change to
polyethylene because it does not rust, it is much superior in an
accident and it does not get affected by the fuels we are currently
using.
The problem in the aviation industry is fibreglass is easy to
manufacture and fairly cheap, you can make round shapes very easily
like the corners of the fuel tank, it does not rust and most
importantly for us, it is lightweight, the downside is it is not
durable when it comes to different fuels.
Polyethylene is used for aviation fuel tanks in some aircraft but it
is about 10 times the weight.....??
There are a number of "sloshing compounds" that can be used which
you mix up and pour into a fibreglass fuel tank and then turn it
around in all directions so that the surfaces are coated and when it
dries it provides a barrier between the fuel and the fibreglass.
The problem with these is that they are not always successful in
bonding with the fibreglass material even when you use the proper
primer and it is because the inside of the fuel tank is nice and
smooth because this is the inside of the mould when it is made and
the material doesn't stick so well....
Something else which is worth looking at is a fuel bladder but these
are also heavy and are quite expensive....
The current alternative seems to be, remove the fuel tanks once
every 12 months, throw a chain inside and move it around breaking
off all the fibres and put the fuel tank back into service.? Clean
fuel system regularly, use a good quality fuel filter that can
capture the fibres and the problems are solved, or mitigated at
least.

Very interesting and valuable
information, as usual Michael.
I will keep my eye out.
I noticed my gascolator valve
leaking today.
My tank has been completely dry for
3 months. I just put fresh fuel in it and I
thought to open the gascolator. Sure enough, it
started leaking. Now I understand what those white
rabbit like hair particles were.
I did notice these particles in the
fuel filter before but now I will clean it more
often.
Many thanks!
It honestly depends on the fuel and the
additives that are used locally when it is
produced.....?? Fuel is not fuel any
more..........
I have seen some excessive fuel tanks deteriorate
in as little as 12 months from ethanol car fuel.
If you have debris inside the fuel tank that is
flaking off the best thing to do is drain the fuel
tanks, put about 3 feet of chain in the fuel tank
and Shake like crazy !?? the chain will break off
any of the exposed fibres, you then need to flush
the fuel tank as many times as you can to remove
the debris and you should be good for another year
or two.
Because the debris is normally fibreglass it is
almost impossible to see in the fuel filter when
it is wet Because it is completely translucent
(just like Glass)?? When it dries out however it
looks white like rabbit fur or something similar
so if you just looking your fuel Filter if it has
a glass Shield you may not see that your fuel
filter is 90% clogged. It is amazing when you pull
the fuel filter apart and the fuel starts to
evaporate it looks like all of these fibres are
actually growing on the fuel filter as they dry
out and become visible.

Re: X Air Hawk fuel tank 'shedding' particles into fuel
Not everyone has a Jabiru engine fitted,?? The Rotax prefers car
fuel.
Either way, the fuel tank in the X-Air aircraft is just vinyl ester
resins and they are affected eventually by fuels of any description,
especially when you have to make it as light and thin as possible.
Best for any fuel still seems to be polyethylene but its heavy.... ?
Look at how many outboard motor fuel tanks there are around the
world that are left outside day and night, in some and rain and use
all sorts of fuels and yet they are still working after 30 years,
can't do that with a Fiberglass fuel tank.

Very interesting and valuable information,
as usual Michael.
I will keep my eye out.
I noticed my gascolator valve leaking today.
My tank has been completely dry for 3
months. I just put fresh fuel in it and I thought to open
the gascolator. Sure enough, it started leaking. Now I
understand what those white rabbit like hair particles
were.
I did notice these particles in the fuel
filter before but now I will clean it more often.
Many thanks!
It honestly depends on the fuel and the additives that
are used locally when it is produced.....?? Fuel is not
fuel any more..........
I have seen some excessive fuel tanks deteriorate in as
little as 12 months from ethanol car fuel. If you have
debris inside the fuel tank that is flaking off the best
thing to do is drain the fuel tanks, put about 3 feet of
chain in the fuel tank and Shake like crazy !?? the chain
will break off any of the exposed fibres, you then need to
flush the fuel tank as many times as you can to remove the
debris and you should be good for another year or two.
Because the debris is normally fibreglass it is almost
impossible to see in the fuel filter when it is wet
Because it is completely translucent (just like Glass)??
When it dries out however it looks white like rabbit fur
or something similar so if you just looking your fuel
Filter if it has a glass Shield you may not see that your
fuel filter is 90% clogged. It is amazing when you pull
the fuel filter apart and the fuel starts to evaporate it
looks like all of these fibres are actually growing on the
fuel filter as they dry out and become visible.

Hello everyone,
I have read that the x air Hanuman comes with two
different types/colours of fuel tanks - one that
is capable of running avgas and MoGas with ethanol
(yellow-ish tan coloured tank), while the other
white-clear tank only accepts avgas. Please
correct me if I'm wrong.???? I have not heard this ???
Anyway, I have the yellow-tan tank that can accept
both grades if fuel. I don't know if the above
information is irrelevant, but after 150hrs of
fuel tank use (14yrs since new), I am noticing
flakes from the material of the fuel tank.
The only fuel that has been run in this plane is
100LL.?
I notice the fuel filter trapping these particles
but why is this happening ?????
The resin is leaching
(being eaten) away by the fuel additives from
the fibreglass and the fibres are breaking off,
this is your "debris" most probaby

Re: X Air Hawk fuel tank 'shedding' particles into fuel
Yes sir - you are bang on.
So what do I do??
Replacing the tank is out of the question for me.
Do I simply and constantly clean the fuel filter every 10hours??

Re: Asi and Vsi and altimeter on X Air Hanuman
You should find the static port on the instrument has ?just not been ?connected, and the static port vents into the cockpit area. Just do not breathe too heavily! (Sorry, not one of my better jokes). Mo.
