| Subject: | Re: Stabalator Flutter |
Alan,
I noted no answer to your question on what is flutter.
Attached are some video sites for you to look at. In engineering,
vibration and aeroelastic concerns on fatique and flutter are very
serious studies.
Please review:
<http://www.aircraftdesigns.com/aircraft-flutter-analysis.html>http://www
.aircraftdesigns.com/aircraft-flutter-analysis.html<http://www.aircraftde
signs.com/aircraft-flutter-analysis.html>
http://www.youtube.com/watch?v=YIHam_isyI8&feature=related
I became interested in the subject when government cuts forced us to go
to a cheaper hydraulic line in the F4. We were seeing numerous problems
with hydraulic failures using the aluminum lines attached. Without
hydraulic pressure, the flight controls did not lock in position in
certain failures (breaking of the control pack) and controls would begin
to buzz at high speed. Luckily the aircraft wing was brutally strong,
we had redundant hydraulic controls and with only one hydraulic failure
we pilots normally slowed down, declared an emergency and returned to
base without incident. One crew lost all hydraulic control on one wing
and the back seater could see the aileron flopping about. They slowed
to 240 knots and the flutter stopped but hinge and trailing edge damage
was evident in only a few seconds of flutter.
Later I was involved in a local Twin Commanche incident where rivets
were popped all over the stab and I was asked to look at it. See the
video below. The type of flutter is evident on stabilators as well as
conventional horizontal control surfaces which are not balanced.

<alancarteresq@onetel.net<mailto:alancarteresq@onetel.net>>
Hello ALL.
This question is nothing to do with how to fix the Toque Tube and stop
flutter.
Ok i know stabalators are more efficient than the elevator, and they
can,t Rime ice up like an elevator and i have flow many aircraft with
stabalators
and i don,t like them.
Question is what is Flutter only??
I keep hearing the word Stabalator Flutter, I have the obvious idea
as to what happens but would like to know more, maybe someone has
experienced it.
Do the Stabalators flutter independently, or both up and down
together,
How fast is this fluttering, How is the on-set noticed in the cockpit,
Can you feel it through the joy stick,( of course you can, but a tell
tell indication maybe in some flight attitude or configuration well
before an event). Is it controllable, What would be the position held by
the stabalators if you had no control. ete,ete,ete, agian not a test
just something we can all chew over.
If anyone has experienced flutter please tell us,
Alan

Wow Bud, that,s pretty scary stuff, have a lot of hours on Twin Coms. glad i knew
nothing about flutter then, what happened to it in the video.
Well i got the first bit right, slow down, but have not that brutal tail-plane
you mention, only have a foam one!, and yes i do have a hang up on tail planes
maybe its because i can,t see it.
There have been some excellent ideas posted on MOD 73 . how to elimination play
and wear in the Toque tube, and this question is just an extension of that topic,
so hoping for some airman-ship replies also.
Regards
Alan

| Subject: | Paint edge around the windows |
Fellow Europas
Does anyone have any suggestions for finishing the Paint edge around the windows?
As the paint does not bond well to the Plexi Glass even after scuffing the
surface.

| Subject: | Aerial testing and fuel smell |
On a flight to the Isle of Bute today I found that the radio was
intermittently failing to receive and transmit. Not a power problem. I have
heard that Europa aerials can be difficult (earth?). How is it best to test
and rectify?
Good news is that the fuel gauge sender unit leak has been stopped by
fitting a 4mm thick nitrile cork gasket ontop of a thin layer of fuel tank
sealant

Dear all again
The upholtsery in G-WUFF is coming adrift - and will be more so after I have
made a few alterations. Can anyone recommend a UK based upholsterer? North
would be better.
Thanks

| Subject: | 914 surging/loss of power |
We are stuck in Lamar CO with 914 problems. Have spent most of the day talking
to Bud for ideas. Flew about 4 hours yesterday, stopped for fuel and lunch.
Takeoff was normal but when leveled off, noted fuel flow was only 3.5 gph, not
the expected 5.5. Increasing throttle gave more MP but same fuel flow. Engine
felt rough or different than normal.
Landed and inspected under cowl - no problem noted. We had just gotten fuel so
thought maybe that caused it. Tried flight this morning when it was cooler,
had to make emergency landing because power dropped soon after takeoff. No vibration,
just wouldn't climb. Found that our fuel tank vent was plugged, cleared
it, ran ground tests & Jim did 20 minute solo test flight with no problem.
Loaded plane & departed again, engine power dropped just after gear retract,
made another emergency landing. (Obvious answer is don't let Heather in the
plane [Wink] )
At this point we're thinking pull carbs for rebuild. Any other ideas?
Thanks, Jim & Heather N241BW

Jim & Heather,
I don't know if this has been suggested by anyone else, but check the carb bowl
pressurization lines from the air box to the carbs. If there's a leak somewhere
along there, it could prevent your carbs from being able to deliver sufficient
fuel under boost. In the attached PDF file these lines are RED, GREY/WHITE
STRIPE and YELLOW. Check VERY carefully! I had two hidden that took three
or four searches to locate. Look carefully at any connection from line to fitting.
If that all checks out OK, then you might also check the carb bowl pressure shuttle
(92 in the PDF) which transfers from lower pressure input to higher pressure
input when you go to high boost. This can be checked by making the purple
connection. Disconnect the YELLOW line from the shuttle and the RED line from
the airbox. Connect the YELLOW line to the airbox where the RED line was removed.
This information was provided by the folks up at Rotax Owner dot Com and
they said that it will not harm anything to run like this till you can get
home and get a replacement shuttle.
I hope this helps. Good luck!

Jim & Heather,
Also, check the pressure line from the airbox to the fuel pressure regulator.
This keeps fuel pressure above airbox pressure ensuring sufficient fuel pressure
to overcome boost pressure. As with the other lines, check thoroughly where
the rubber hose meets a connector. These areas are prone to splitting.
