On the other hand, there are many Rotax engines flying fine every day
with E10. Rotax itself has said it is OK for the 900 series engines.
For the standard Europa-supplied tank, E10 has no obvious effect, not
in my A224 which has been flying more than 5 years with nearly
exclusively E10. At my fifth annual inspection, per recommendations,
I replaced all of my fuel hose. There was no sign of interior
degradation, but I replaced the Gates R5 hose with R7.
If I had been particularly concerned I would have selected Aeroquip
666 teflon/carbon hose which has an infinite service life. It would
have required however replacing all the fuel fittings from barbs to
AN fittings from the tank to the engine.
If E10 is the only mogas you can obtain, it is still better for the
engine than leaded AVGas

Subject: Europa-List: DOTH Turweston Sunday 13th
Hi Folks,
Having been grounded for so long by the wind and rain, things have settled
down - albeit with morning fog.
If the fog clears in time, I hope to make Turweston ( hard runway, voucher
in Flyer ) on Sunday 13th. I usually say 1200ish, but I'll get there when I
can!
All the best, Paddy
Paddy Clarke

An extremely detailed research programme into MOGAS and related subjects
has been commissioned by EASA. Barry Plumb of Light Aircraft Association
(the UK homebuilders and GA pilots' association) is a member of the
panel undertaking this research. The project is very nearly finished,
and it will then be published on the EASA website. Barry will prepare a
pr=E9cis of this report, and when that has been put onto the LAA
website, I will advise you all of the link to it.

Subject: | Europa pitot-static probe warning |
Today I made a disturbing discovery.
Some time ago I checked that my pitot static systems were leak free.
Pitot would hold pressure over a few days, static, with much more
instruments coupled to it, would hold it over a few hours. I tested this
with a syringe connected to the tubes that went to the pitot- static probe.
So, with much confidence I went today to the official mandatory pitot
static test. To my dismay, the static system appeared to have a massive
leak, with the altimeter set to 1000 feet, it would go down to 0 within
a few seconds, pegging the VSI in the corner.
Tracing down the leak, it didn't take long before I discovered that the
static probe itself was the culprit! (I had not included it in my own
test because it was sort of difficult to connect a tube to it, and it
was of metal after all so I somehow trusted that this thing would be ok).
The static probe consists of a tube with an inner tube inserted into it
to allow a standard diameter hose to be fit. This was where the leak
was: between the two tubes. When I tried to disconnect my test hose from
the tube, suddenly the inner tube came out of the probe!
It is unclear if and how the inner tube was secured to the outer tube. I
can't see traces of solder or welds, nor from any type of glue.
As this is a piece of equipment originally delivered by Europa with my
kit, it may well be possible that other pitot-static probes have the
same problem. It might go unnoticed for a while, and maybe after a while
it starts leaking. If that happens, the static system will now be fed
with air from the inside of the wing, and this pressure might be far
from neutral.
So, if you a bored, you might screw off the probe and have a good look
at it, and maybe as a precaution, use some sealant over the joint
between the two tubes.

Subject: | 309 Stainless Steel tube |
Hi All,
I was wondering if anyone while they have been traversing the vast space of
the internet
has found a source for 309 stainless steel tube.
I need about 3 feet of 1.5" tube, or even better an OD of 40mm
Jason, I have put you on copy because I know you manufacture a nice
exhaust/turbo system for the 914 and you might be using SS 309.
Thanks, Paul

Paul,
onlinemetals.com has 304 SS & 316 SS...
burnsstainless.com has 304 SS & 321 SS...
what's special about 309?

Hi Paul
"I was wondering if anyone while they have been traversing the vast space of the
internet has found a source for 309 stainless steel tube."
I first question if you really need 309?? I know Rotax is now using 309 on new
style exhaust, they used to use something else. Is your exhaust 309?? Old style
is said would be lucky to last one TBO, 309 is expected to last at least a few
from what I understand.
Anyway if you are just wanting to make a new exhaust pipe I think 304 should be fine. You can weld 304 to 309 with 308L welding rod, www.mcmaster has both.
If you want better heat resistance they sell 316 tubing in 1.5", I am pretty certain
you could weld 316 to 309 with 316 rod they sell, but not certain 100% on
that so check , McMaster sell both.
321 stainless is used in aeroplane exhausts, better for temp than 304, I didn't
check if McMaster sells, but Spruce sells, not sure if you can weld 321 to 309
and what rod if you can but if you just need it for pipe which would be overkill
but better for temp than 304.
I have looked for 309, not too successful, however McMaster sells a 1.5" 3' long
rod, you could knock yourself out and bore it out, probably would need to cut
it down to bite sized pieces and weld it back together after you made a pile
of chips.
You may want to consult with an aviation muffler/exhaust specialist. Have a look
in Trade a plane, think Dawley is one that has a good reputation.
I am installing a mixture control on my 914, to monitor how I am doing. I will
be welding a 304 stainless bung to my 309 muffler using 308L rod. The bung will
hold a O2 sensor and drive a mixture monitor which I will use in addition to
two EGTs. I researched in past and 308L is a good choice for welding 304 to
309.
Off topic a bit but will stand on my soapbox and mention more ethanol is needed
compared to gasoline to achieve proper mixture. Thus E10 will run leaner than
gasoline with no alcohol with same tuned type 64 Bing carb. Especial on a 914
that you modified the intake track (inter-cooler is just such a modification)
when you are making some BTUs you want to be sure you are rich enough. Rotax
wants you to measure carbon monoxide on each cylinder when making war emergency
power (115%). They issued a bulletin a while ago that is still in effect to
make sure you are not lean. I will throw a dart and say they will probably bring
this up again in a service bulletin when using E10 in the future. I like Bing
type 64 carbs, if anything I want to run a tad bit rich when making some BTUs,
and OK to lean when you are not.
Off soapbox.
Good luck
Ron Parigoris
BTW if you are mutilating your exhaust and want to fool with a mixture monitor,
I am using Split Second ARM-1
http://www.splitsec.com/
Nice small unit driven by a O2 sensor. Since you are not driving a computer that
is using info to adjust mixture, even with 100LL use sender will begin to slow
down and yet still be fine for monitor. Dart throw is 100 to 200 hours with
100% 100LL. There is a routine upon start up that will tell you when it is time
to replace sender

Not sure if this helps but ACS has 321 stainless which is good for temps of
1500f, if that is high enough they sell by the foot
