Morning all.
Just saw a flap actuator for homebuilts on ebay if anyone is interested. It wi
quite unlike other types I have seen but looks to be simple enough. see Item
number: 4537373537
Have a great day - spring is here (at least on the calender)

Thanks Johann and thanks Grant for the detailed response! I found his
website - very interesting. Seems a similar thing happened to Brian
Milton trying to cross the Atlantic in a trike, the bureaucracy doesn't
cope well with modifications to the aircraft. I'll definitely keep an
eye out for his book.
Thanks again and I may well be in Iceland this year (or definitely
next) and by airliner. It would be great to meet you Johann if I can.

Hi Group
If you don't have a Rotax 912 or 914, or know someone who does, you may hit
delete.
I had my CH601HDS, Taildragger, inspected on Nov. 11, 2004. I did not have
my medical back yet, so decided to short hop a couple of more times that
afternoon. At 60 MPH, just at lift off, the engine (912 UL) seized. The
airplane made an automatic wheel landing and I coasted off the runway. 27
hours total on the Hobbs meter.
The seizure was due to oil starvation. Destroyed the crank, cam and two
cylinders to the tune of $6,886.91 (US).
Why oil starvation? I had installed the oil tank according to the oil
system installation instructions on page 35 of the 912 Installation Manual.
The illustration of the oil tank is incorrect. The oil tank is plumbed
internally the reverse of the illustration. Follow the illustration and you
will connect the line to the oil cooler/oil pump to the return side of the
oil tank and the return line from the engine to the supply side of the oil
tank - I did.
How do you get 2.7 hours run time? I changed oil three time during that
period. The procedure I used resulted in excess oil in the engine case
which was pumped back into the oil tank, over filling it so that the oil
level raised to the point that oil was transferred back to the engine
through the top of the tank. At lower RPMs this seems to have lubricated
the engine fine, and yes I had normal oil pressure indication. On the last,
disastrous run, I had done a full power check on the runup pad prior to
taxing to the runway. I appears that at full power, the tank was filled to
the point that oil blew out the overflow. When starting this short hop run
I do not recall rechecking the oil pressure prior to advancing to full power
- I was concentrating on oil/coolant temps. and RPM.
Rotax has agreed to pay 1/2 the repair bill and is busy correcting the
Installation Manuals, Service Bulletins and Service Instructions on the
Rotax Owners web site. The 912 & 914 engines use the same oil tank and
illustrations for both engines show the reversed drawing.

Leo- That sucks! At least they agreed to pay for part of the repair. I'm
not sure I'd be real happy with that since it's their mistake. I would want
them to pay for the entire thing. Oh well, at least your ok and your plane
can be repaired.

Leo,
That is quite a story. And hopefully you are helping some others to catch
this error.
I am using an older edition of the installation guide and I just double
checked their plumbing diagram. It is correct (1998) so they must have
changed it since then. It makes sense that if this tank is hooked up
backwards, the suction on the tank is no longer performed thru the tube that
goes to the bottom of the tank, so there would be oil starvation in short
order.
Fantastic that you got them to pay for half of the repair... still your half
is a lot of money!
You should ultimately have a service bulletin issued in your honor! Will be
watching!
Good luck
Jon

If the installation instructions AND the illustration are incorrect, and it

major failure!), I'd want a NEW engine. In fact, I would DEMAND a new engine
from Rotax. And they should be happy to give you one....and thank their lucky

I thionk your very right Dave. If this had happened to me or someone I knew
and they ended up getting hurt bad or worse yet killed because of this I
would hit the roof. If I was this flyer I would go after Rotax with
avengence and to tell them they're very lucky they aren't getting sued over
this. It was there mistake in the manual, not the builders fault.

Jon,
My Installation Guide is Dated 1997, Rev. 1 Dated 1998. Part No. 897 711
Take a close look at the illustration (Page 35 of 66). It shows the oil
line to the oil cooler and oil pump connected to the fitting on the left
side of the oil tank (vent fitting facing left). The fitting on the left
side, in fact, ends on the top of the oil can
and does not continue via a tube to the bottom of the tank - that is on the
other side.

Randy,
Note that this happened in Nov. 2004. Rotax does not do anything in a hurry
Their first answer was, "It is not possible to hook up the oil tank
backwards
and have oil pressure," so my fault. My answer, "2.7 hrs. on the Hobbs and
I know that the first thing you check when starting an engine is oil
pressure."
They then offered to pay 20%. More delay, then they decided to pay 1/2 with
the observation that it is almost impossible to sue them since they are in
Austria.
At least they are finally cleaning up the documents. My engine is being
shipped
from Lockwood Aviation in Fla. tomorrow.
FUI Phil Lockwood has been caught in the middle during all this. Customers
can
not talk to Rotax directly, you must go through the repair center. Phil was
on my
side and spent hours and hours on the phone.

One reason I did not post the information sooner. I wanted to give Rotax a
chance
to announce the problem on their own.

Since Zenith's gascolator lacks a screen, I've installed inline filters.
My tech counselor suggested I purchase a regular gascolator and do away with
the filters and, being a cheapskate, I said I'd check with other Zenith
builders.
Any feedback?

Leo,
The instalation and first fill up of oil is very important in the Rotax 912 (no
914 here, sorry) In our Club we have 11 engines already installed and flying,
one with about 800 hrs already.
Our mechanic was sent to Kodiak (some years ago) for especial 912 training.
The most important thing is to bleed the air from the oil system the first time,
before the engine is started.
Another inportant thing is the oil level check procedure. with the tank cap opened,
IGNITION KEY "OFF", turn the prop forward until the tank makes a "fast
drinking coke" :-) sound. This means that all the oil from the crankcase
is in the oil tank.
Saludos

I'm not at that point yet, being still immersed in the front fuselage, but I am
planning to use an old Cessna 172-style gascolator, either at the bottom of the
firewall or just after the fuel selector. It not only contains a filter, but
also has a pull plunger to quick drain from above. Saves groveling around under
the bird.

Yes, I had the lines full of oil - no air. I did not know about the "fast

Hello Leo and group.
Sorry to hear about your misfortune on the Rotax engine.
If you read this installation instructions from their manual, and it does
not work that way, it looks like they should be responsible for the fault.
Just my opinion.
They charge you enough already for parts to cover minor repair like this.
Just glad no one got hurt.
I would like to know if the Zenith instructions are correct.
The outlet from the oil reservoir tank is on the left side and connects to
the left of the oil cooler. Then it is connected to the engine on the
right lower side beneath the oil pressure sender.
Then it exits from the bottom of the engine back into the oil reservoir.
Is this the correct understanding of the oil flow?
I just bought the engine oil today, and am about to go through this same
ordeal.
Good luck with your new engine and getting Rotax to pay for it.
Best wishes,
Johann G.
Iceland.

Leo,
Now I see what you are talking about... this diagram, which has been
printed for many years in the installation manual, is ambiguous at best, or
simply wrong when you consider the orientations of other ports on this tank
in their diagram. I concur that this drawing depiction is at best,
confusing. There are other ways to confirm proper hookup, but I agree that
if you used this diagram alone, you would hook it up wrong!
(to our many 912 owners: take a look at YOUR installation manual.... the
tank picture is drawn a bit incorrectly... if you were a print draftsman,
you would have to agree that there are some mistakes here!)
Thank you for pointing this out to many future installers!
Jon

Johann,
You have identified the the crux of the problem:
WHAT is left? (Kinda like what is life?) It depends how you view the tank:
from the front or the back? What is the front of the tank? It is ROUND!!
So... the port on the top of the tank labeled "OUT" goes to your oil
cooler... and then into the engine (the oil leaves this "OUT" port and goes
into the cooler and then into the engine). The BOTTOM of the engine (the
output) routes to the remaining port on the tank.
Please, No more left and right... this is the problem.. the drawing is
wrong... depending how you view the drawing ( back/front/left/right!)
Clear as mud? !
Jon

Johann,
I received no instructions from Zenith. If you position the oil tank so
that the vent on the neck is pointing to your right, then your understanding
of oil flow is correct.

Hello Leo and group.
I would like to know if the Zenith instructions are correct.
The outlet from the oil reservoir tank is on the left side and connects to
the left of the oil cooler. Then it is connected to the engine on the
right lower side beneath the oil pressure sender.
Then it exits from the bottom of the engine back into the oil reservoir.
Is this the correct understanding of the oil flow?
I just bought the engine oil today, and am about to go through this same
ordeal.
Good luck with your new engine and getting Rotax to pay for it.
Best wishes,
Johann G.
Iceland.

Jon,
There is only one way to view the drawing. The overflow/vent on the neck is
clearly pointing to the left.

Bob,
I've a standard gascolator with filter screen at the bottom of my
firewall, a paper filter above the pumps, soon to be
replaced with a stainless filter, and the Bings have filters above the
float bowls. I added the paper filter when "swarf"
from my fuel tanks was seen in the sample drained before I'd go flying.
In the sun it looked like a miniature tornado of
microscopic glitter. After a seeping shutoff valve was replaced, the
tanks were drained, the finger strainers were unclogged,
the tank was brushed and wiped clean. The glitter was gone for good. I
like the assurance that the in-line filters offer
as an additional hedge keeping the carbs from catching the small stuff.
Before the paper filter, I was finding the same
stuff in the Bing bowls and in the gascolator bucket. I'd keep an
inline filter in the inventory and reconsider a standard gascolator over
the unscreened ZAC model.

I used the ACS gascolator and bracket from Spruce and Wicks. It has a
screen. My 701 came with no gascolator for the firewall, Just boxes for behind
the
seats to combine the
tanks.

Why did Rotax only agree to pay half the repair cost if the problem was
their manual? Seems to me we should put some pressure on them to be more
accountable.

Leo,
Here is the link to Zenith's installation method on the Zenith 701. It
should be the same for the 601.
http://www.zenithair.com/stolch701/data/r912s-s4.pdf
It shows the oil vent pointing to the right.
Regards,
Johann G.
