Both my doors are bowed about 1/8 to 1/4 inch.
Any suggestions?

| Subject: | Re: What did you do with your Europa 4/11 - 4/18 |
Pete,
I had the same issue with the vibration when I got over 5000 RPM. Did an analysis
which I include as attachment. You can see how the vibration spikes as the
engine RPM crosses 5000 RPM and it is indeed a peak corresponding to the engine
RPM frequency.
Clive Sutton had a theory that maybe the carburetors where resonating and causing
issues.
According to RPX (DynaVibe) they indicated it was a carb balance issue at those
RPM. Bud once had a writeup on how he had issues with carbs not working in unison
because of age and only going to new carbs solved the issue. Since the carbs
were a bit old that is certainly a possibility.
But I have to report that I bought a new engine and the vibration is gone.
Can I conclude it was a problem with the engine? no I can't because before before
I flew the airplane with the new engine I removed the cone K&N air filters
I had and installed the cold air plenum (too many changes). So three possible
reasons:
1.- Something off with the old overhauled engine (kind of broad)
2.- Old carburetors coming out of balance at high end
3.- Vibration on the supported carburetors. I was told my carb support spring were
a little soft.
For some time I thought the culprit could be something in the airframe resonating
but with the vibration going away with the engine change that is not high on
my list.
I hope this helps.
Chris

Thanks Chris!
Indeed my Smart avionics balancer spectrums were identical to your attached
report. Nice to see I'm not alone! ....and I'm not going crazy ;-)
Question: do you know if your old engine had experienced "case fretting"?
I checked my carb balance throughout the RPM/throttle range, and they are
indeed fine in the 4400-5600rpm and throttle ranges in question. Diaphragm
tensions also felt identical. I did however replace the rubber carb
mounts, which would indeed change the resonant frequency of the carb
assemblies. I have tried moving the spring mounts further away on the tube,
adding tension...no difference. Your suggestion however will prompt me
to try adding some mass to the airbox - to see if the resonance moves down
the rpm range..... sweet. I was running out of things to try LOL.
As my resonance only occurs at cruise speeds and loads and not in the
climbs, I was suspecting possible aero causes (as the three blade prop
pulses are also in that 80ishHz range) and instrumented the tail etc. but
to no avail - nothing different than when I instrument the tunnel mount
points, so nothing is getting excited back there. So I'm back to the
engine, or something on it going into resonance. I have already eliminated
the exhaust from the possibilities by springing and massing it with no
change.
I have obviously also looked for any hard interferences between the engine
and the airframe - none.
The mystery continues..... but I hope messing with the airbox mass may
give me a clue.
Cheers and thx again!

| Subject: | Re: What did you do with your Europa 4/11 - 4/18 |
Hi Pete,
Well, we are all a bit cray but no, you are not alone :)
The engine I had was rebuilt by a Rotax Repair Center (actually recommended by
Rotax). Had a number of very unique issues with this engine until I decided I
wanted to spend more time flying than learning how to fix a Rotax (which I really
did!) so I bought a new engine (honestly, best investment in my airplane so
far).
But I saw no evidence of case fretting.
One day I will repeat the analysis with the new engine just for the fun of it.
But I can tell you that with the new engine the feel is very different.
BTW, after a long chat with Phil Lockwood he explained to me how a simple issue
with an older gearbox could cause vibration in the same way I was feeling. Basically
a small depression where the clutch dogs rub. If this is not caught during
rebuild he says it can generate vibration and it feels as if a switch was
flipped at very specific RPMs. My gearbox had been "rebuilt" but who knows.
My lesson with the Rotax so far is that it is a wonderful engine but a bit finicky.
It seems that small things will make it run not as smooth. But maybe I am
wrong in my assessment. We will see how my experience with a new engine from
the start is.
Best Regards,
Chris
