Just wanted to amend my previous request for a couple hours of dual.
As someone point out off-list, we are only allowed to SHARE the cost
of the flight, I can't compensate you due to FARS.

| Subject: | 532 Engine failure in a 701 |
--> Zenith-List message posted by: "Mike Banyai" <mbany@freeway.net>
I recently had a Rotax 532 fail on takeoff with total shutdown due to piston burn
through secondary to overtemp. The specifics are as follows---The engine was
recently overhauled and zero timed after sitting for 12 years. It was put back
onto the plane where it had first accumulated 50 hours in 1991. The engine
had been upgraded to electronic ignition, and the water pump modified to deal
with the known failure mode there. Because of the water pump mod I had to move
one leg of the engine mount back an inch and then the aft muffler attachment
point also was shifted back an inch. In retrospect this charged the the direction
of pull on the joint from forward to more neutral. The engine had been
returned to me correctly jeted with an hour of test stand time with my prop and
muffler. This was ealy June of 04. Over the next three months I put about
6 more hours of ground static time on the engine. The muffler had been problematic
the entire summer, never quite able to get a decent seal on the connection
between the manifold/muffler conection. This would result in some gas leakage
that would overheat the springs which would become loose. I used a duel exhaust
gas temp gage as my gold standard as to how to adjust the carbs, but it ran
a cool 950 degree F. at he main jet size that was given to me(185). Over a months
work and mutiple replacement jets the temps did come up to 1100 at 5800
and back to 1050 at max rpm of 6200 with main jets of 155, which seemed to make
some sense as this is what is recomended on the charts..We then put another
2 hours on the engine getting various kinks worked out..Never did it run more
then 1100 degrees, air or ground. Then last Wed in an attempt to finally get the
muffler problem fixed I moved the attachment point back to the orginal spot
and double springed the joint. I then taxied for about 10 min. All was well
and temps seemed OK. I did not do a ground staic run up to max RPM while tied
to my car as I had done all summer with each carb adjustment simply because
it never occured to me that I had impacted the carburation system. On takeoff
at max RPM we began to loose power and while turning back the engine quit. We
landed on tarmac hard but no major dammage. I think that all summer the tunned
pipe exhaust never really worked as well as it should and once I got the seal
established the engine sucked more air with same amount of fuel, efectivly leaning
it out to the max with subsequent temp rise to the 1400 degree range. I
can't really say what the temps were on takeoff at max RPM as my attention was
on getting back earthside in one piece. I did note at one point that the RPMs
had climbed to 6600, something that had never happened before. The outside temp
was basicly the same that I had all summer, so I don't think you can blame
either air temp or altitude for the problem.
Takeaway lessons: 1) Always do a ground staic check after any engine modification,
regardless of how minor it seems 2) Its the little things in sequence that
will kill you. Had the muffler attachment not been moved I would still be flying
today with the 185 jets, happy as a clam... Mike Banyai, Petoskey/Pellston

Lists...?

[Just one more day to get your vote in... -Matt]
Dear Zenith Listers,
I have received a couple of requests recently asking if I would create some
model-specific lists for the Zenith-List. Specifically, a 601, 701, and
801 List have been requested. I personally think that splitting the List
will generally reduce the over all content and I prefer the single
list. Discussions breed other discussions, and so on and that's what keeps
the list alive and healthy.
That being said, as the List administrator, I want to provide the kind of
service that the members want, so I'm open to discussion on the
topic. Rather than chew up a whole lot of bandwidth on the Zenith-List on
the subject, I have created a simple survey form that will allow all the
members to vote on what they personally would like to see.
Basically, there are three options:
1) Keep it the same. One List (Zenith-List) that services all models.
2) Add three new model-specific lists for the 601, 701, and 801.
3) Add two new model-specific lists; one for the 601, and one for
the 701/801.
In all three cases, the current Zenith-List will remain as is. I will run
the survey for 7 days ending on Sunday September 26th at 12 Noon PDT. At
that time I will tally the votes and post a summary to the Zenith-List.
Below is the URL to the survey form. Upon completion of the survey, you
will receive an email confirming your vote. Please fill out all
information on the form. Forms without Name and Email won't be counted,
and duplicate submissions will be deleted.
http://www.matronics.com/zenith-list/survey.html
Thanks for taking the time to fill out the survey. The more people that
fill it out, the more accurately the results will reflect what the Zenith
Listers would like.
Best regards,
Matt Dralle
Zenith List Administrator

You are absoultely right Andy. You can't. But if someone is going out of their
way to help you out you could buy that old 360 channel radio or that old pipe
wrench they have sitting in their shop for a reasonable price. Jack

In the not too distant past, I've seen pictures of landing lights in the slats
on a CH701. Would some kind soul please remind me as to where I might view them
again.
Thanks in advance,
