Hi All,
There are still two openings in the March 4th - 6th Jabiru Engine
Maintenance & Repair seminar at Jabiru USA in Shelbyville, TN. Cost for the
weekend school is $300.00. Contact dana@usjabiru.com for more details or

> Hey Tom,
I haven't heard anything directly from Jabiru about this, but it doesn't
surprise me in the least. The tanks are probably fiberglass and a lot of
manufacturers with fiberglass tanks are finding out that ethanol dissolves
epoxy resin over time. I was just in Sebring last month getting Rotax
912/914 maintenance certification because I own a Ximango motorglider with a
912s installed, in addition to my Europa with a 3300 installed. I stayed for
the Sebring LSA show to drool over all the new toys after the training.
While I was there I was collared to help the Pipistrel rep, Micheal Coates,
rig his Virus LSA for the show. I noticed he had two extra sets of wings in
his trailer. When I inquired as to why he said they were going to Robert
Mudd, a composite repair guy in Moriarty, NM, for repairs to the fuel tanks
because of ethanol poisoning. I've heard it's happening in boats, too.
Ethanol is bad ju-ju. We haven't seen any come through our composite shop
yet, but we figure it's only a matter of time.
Sure am glad I can still get ethanol free UL93 here in Tennessee!

| Subject: | Jabiru rescinding approval of ethanol fuel? |
The referenced advisory rescinding auto gas approval applies only to S-LSA
aircraft produced by Jabiru USA. We issued it because of growing evidence
from our LSA fleet plus many reports from operators of amateur build
aircraft of fuel system problems emanating from some of the additives or
contaminants in auto gas. We've received many reports of a stringy mucus
like substance precipitating out of the fuel solution that clog fuel filters
and gum up carburetors. We've received reports of this happening in
fiberglass tanks with sealants, plastic tanks without tank sealants, and
even welded aluminum tanks with no sealants. This substance has been the
suspected cause of at least one fatal crash. We've received no such reports
from operators using Avgas 100LL.
Searching through fuel test reports from gas stations across the country we
find that a significant number of samples reported contaminants such as
acetone, mek, toluene and other minor keytones plus the deliberately added
components like ethanol, methanol, mtbe and tame. There is now good
research that I could find on the effects of long term storage in fiberglass
tanks.
While our tanks are sealed with a product that is resistant to 10% ethanol
there still seems to be a potential problem in every day use. I think that
the effects of some of these additives and contaminants coming out of the
solution (or suspension) with the fuel and settling to one area of a fuel
tank in higher concentrations than expected is unknown and potentially quite
damaging. While Jabiru Australia has had coupon samples of fiberglass
coated with the sealant immersed in a gas - ethanol solution for nearly two
years with no apparent damage to the sealant, there has not been a field
study of E10 in a real tank exposed to moisture and condensation that may
cause ethanol to combine with water and fall to the tank bottom in higher
ethanol concentrations than expected.
My advice to operators using auto fuel - either with or without ethaonol -
is to keep a really close watch on their fuel systems. Carefully inspect
fuel filters and carbs on a regular basis.

I just received this link from a Rotax engine pilot. It refers to a problem
with
ethanol laced fuel in fuel tanks with some sort of sealant. It has nothing
to
do with the engines themselves.
