Well at least the differences seem to be exceedingly minimal. The crankcase SB
that affects mine doesn't look like a hard "AD" where you're flying on spit and
bailing wire. Having read through it, looks like a cautionary inspection regime
for a condition that can happen under certain cases of abuse.
i.e. long as you run a balanced prop, don't overreve or overheat, keep carburetters
balanced, maintain the gearbox, etc., it should hold together normally.
So we could probably still run our motors to 2000hrs or more, just not at the blessing
of Rotax.
I still have about 1100 hours and about 5 years to go on mine and I may not even
be able to hit that on this particular airframe....

Hi Dick,
It is only 168 pages. It will cost much more to buy an actual copy. You will only
use 1/4 ream and very little ink for this. Some of the real printed manuals
are in the area of $49.
Everyone should take a short break when you get this and really read it. There
are some changes. This is the largest change I have seen in years, not just a
few sentences here and there. I'm sure some of this comes out of research, peoples
experiences and the new 2000 TBO program.

Lucien,
Let's look at it again.
What's your engine serial number and do you know what year your was Mfg. or at
least close? Almost everyone got an extension that owns a 912. The pre 2006 guy's
only need to make to simple mods.

Hi Roger,
I'm pretty sure I'm SOL. My motor's ser. no is 5644130 (a 912ULS). I'd estimate
it was made in late 2004. The original builder put it on the plane in Jan. 2005.
Looking at the TBO extension SB, this falls right in the upper edge of the range
where new crankcase halves are needed to qualify for the TBO. I uncovered SB-912-029
which has the exact same latest ser. no. in its range as the TBO extension
range for the crankcase halves.
Mine of course has not been apart since new...
A huge block of 912ULS engines look like they're excluded because of this CC SB.
If I were Rotax, I'd say that's the right thing to do too given this particular
issue (possible cracks in CC) so this isn't weird to me.
Not too big of a deal as I still have 7 years and 1140 hours to go on mine... just
kind of irritating ;)

Hi Lucien,
You might be right. It's a new day and I sat down and read the TBO SB this morning
with my microscope, it was just too late last night. I took a long hard look
at the TBO bulletin and the one you suggested. So long as your crank case number
is greater than 27.811 or the production year is 2006 your good to go or
your engine number is 5646560 > your good. Previous to that you may not qualify.
A new crank case is $4500. Personally I think they could have included those
other engines. If they are good up to 1500 hrs. then they will most likely
be good another 500. They could have just added a special check or make you put
an additional comment in your maint. logbook.
You know if enough people were to write to Rotax overseas and state such a thing
maybe they would make an addition. Never hurts to try.
Rotax owners speak up an be heard. All they can say is no and you would be no worse
off. Might as well ask, but make sure you ask you also give a solution and
don't just complain. Give them a good idea like a additional logbook entry at
each 100 hr. inspection. They do make revisions to SB's.

Well... $4500... + taking the engine all apart... + who knows what else.... may
as well get a new engine. Regrettably, the 912 is also pretty much a throwaway
like the 2-strokes once you have to do major stuff like a rebuild or replacing
crankcases and such due to the excessive parts costs.....
But apart from that, since mine's in an experimental, I go on-condition anyway
so the paperwork aspect of it isn't that big of a deal for mine. I'd feel confident,
given that the motors that qualify aren't substantially different from
mine and many others that dont, I could go on-condition up to 2000 hours with
it (as long as I also do the additional maint, and the CC inspections, etc).
So far it's been a good engine. I do have to do a carb balance and get the friction
torque checked tho ASAP. But it looks like it's going to last a while...

That's the nice thing about experimental's is you are allowed to go on condition.
Many owners don't do 100 hr inspections with an oil analysis and other inspections
from the line maint. manual along the way, but I would highly recommend
it and it is pretty much what's called for for the on condition program. I'm
sure you'll easily make 2000 +hrs.

I think you can walk into any Kinko's with a PDF file and they will print it
for you. I suspect they can do the same if all you have is a link to the
web.

The TBO of aircraft engines is simply a recommendation from the engine
manufacturers. When flying behind an engine under part 91 of the FARs',
there is no requirement to overhaul any aircraft engine when the engine
reaches the recommended TBO. On the other hand, when the aircraft is
used for higher, such as in a flight schools, a 135 air taxi, etc, that
is when the engine must be removed and overhauled when they reach TBO.
Basically those flying certificated, experimental amateur-built
aircraft, ELSA, and SLSA airplanes are free to fly behind the engines
far beyond the TBO, as long as they are signed off and determined to be
in airworthy condition at the annual, or conditional inspections.

I think and I may be wrong, that if you never leave fuel sitting in your
plane then you will have little to worry about in the dissolving the tanks
department. However defueling after every flight could be a pain!

Another thing that happens is any varnish or other deposits left behind by
gas are dissolved and cleaned out by the ethanol. So if your system isn't
already clean, the dissolved debris can make it up to the filter, or into
the carbys and the engine.... stopping or slowing the prop....
So you have to make sure the whole system is clean before switching over to
E10 and eagle-eye the fuel filter on pre/post flight for a while after you
switch.
I use a large clear paper fuel filter (no, I won't participate in the fuel
filter thread again ;)), rather than the recommended small ones with the
rock-like or screen elements. This way, the extra size and filter area gives
me a fighting chance to catch any clogging on pre and post flight before it
actually plugs up and kills the engine. The little filters clog in a NYC
second, but the big ones take a while and hopefully you arrive at your
destination before it plugs completely up.....
