Pete,
I too recently experienced an increasing amount of "sub idle resonance" on
start up from cold on a 912 - exactly the same as your description.
I contacted Nigel Beale at Skydrive who informed me that this could be
either the sprag clutch slipping and not turning the engine fast enough
before the first cylinder fired or an inadequate torque friction setting in
the gearbox. In any case, Nigel recommended immediate action to fix it
because he warned that repeated bouts of sub - idle resonance would
seriously damage the gearbox.
I decided to remove the gearbox (straightforward job, with due care to avoid
damaging the mating surfaces, from the Rotax Maintenance Manual) and take it
to Skydrive for re-shimming and was delighted to find that this has
completely fixed the problem.
Apparently, due to operational experience, Rotax have found it necessary to
increase the specified friction torque (which reduces in service due to wear
and a number of factors such as too slow an idle speed and carb imbalance).
I'm not saying this is the answer to your problem but it may be worth you
checking your friction torque and if necessary getting it re-set to the top
end of the latest specified band, as recommended by Skydrive.

<<what the Rotax dealer in the UK
describes as 'sub-idle' >>
Which in another language is torsional resonance. Every engine has
this,
especially with a larger flywheel (the prop) coupled by a spring (the
face
cam device at he front of the gearbox) to the crank.
This natural resonance usually occurs at sub-cranking speeds and is
not
excited by the smooth constant-level torque supplied by the starter
motor.
The starting system is usually designed to crank the engine above the
resonant speed. Once the engine starts to fire then, if this is at the
resonant speed, the resonance is massively excited. Resonance absorbs
a
vast amount of energy so, even if the engine is weakly firing, it may
not be
able to "power through" the resonant band.
So the problem could yet be one of the starter not spinning the engine
fast
enough to get through this low speed phase; Or improper adjustment of
the
preload of the "dog clutch" which effects the resonant frequency. Or
different prop inertia.

It's been many moons since I've been on here due to launching of a new
business. After two years and only 15 hours of progress, (800 before that)
I've decided I need help to get over the road block.
I am looking for someone in the U.S. who is experienced with and can
complete the filling/sanding and priming of my monowheel XS. Anybody know
someone they can recommend who does this type of work?
Thanks!

Yes that is exactly what it does. My engine started cold fine but would
not come up to idle speed. Ran as if only 2 cylinders were firing, very
rough with lots of vibration. It would take several attempts to get it
to run smooth. Once it had fired up once then it was ok for the rest of
the day. I believe it is the kick back that damages the sprag clutch
but the bad starting, going into what the Rotax dealer in the UK
describes as 'sub-idle' it the result.

Can a sprag clutch problem cause rough running after the starter is off
(i.e., sprag clutch not disengaging)? I have been ignoring the sprag
clutch/heavy-duty starter discussion, assuming that it referred only to
kickback and other problems while the starter was actively driving the
engine (problems which we haven't experienced).
Thanks to all who have offered suggestions. We have carefully set the
clutch cables so that both chokes hit their limit stops at the same
time. We have also checked the temperatures of the exhaust pipes (both
by feeling and by EGT reading) after a few seconds of rough running, and
no significant difference was found between the port and starboard
sides.
Today we tried replacing the fuel in the float bowls with fresh auto
gas. No help.
After a few seconds of rough running, the port side carburetor sometimes
overflows fuel into the air box, probably because the float needle gets
shaken off of its seat. Cylinders 2 and 4 are then quickly flooded,
which can be overcome only by opening the throttle far too much. We'll
try starting with the fuel selector off, to see if we can avoid the
flooding.

John, Isn't this a case of designing in failsafe mode? Getting the boost set
in max isn't the end of the world as long as you know about it, since
throttling back should make everything manageable. If you had the wastegate
failure mode giving zero boost then you could be in serious stuck if it
failed on you when you were high up in inhospitable mountain country, or
trying to climb out of somewhere hot, high and heavy. I appreciate that
getting either a surge in power or a drop in power could be pretty
distracting when you are in a circuit situation, but I think I might go for
the surge personally!

Hello Group
I noted that many of you have installed the Bob Archer nav/com and
transponder antenna in your aircraft. I wonder if any have chosen the
Advance

Electronics units which are also available from Spruce. These units are a
bit
more expensive than the Archer units. Worth it?
I would like to hear from you!
On another note. I have uploaded a few Sun N Fun photos in my area of
Europaowners.org. They include a visit to Deans house to check out his

Thanks in advance for any information on antennas.

Perhaps another case of "you've been told by the manufacturer that the
engine may stop suddenly without warning". So if it does, its your fault
either if you didn't expect it or didn't control the ensuing situation!!
This culture seems to serve in lieu of a proper fix in the first place.

Appears no doubt their VHF antenna is a straight leg dipole, whose
length has to be a compromise between COM and NAV frequencies. The
straightness of the legs is also not what you want for best radiating
pattern, and the fact that metal whip antennas are angled is not just
for aesthetics. Whether AC Spruce misleadingly calls them "high gain"
or the mfr does, doesn't matter either, as one cannot alter the
physics which results in a fixed gain of 2.15 decibels (dBi). So much
so that a straight dipole is also a reference for specifying gain of
actual hi-gain designs (dBd, the third character meaning "dipole").
So how she performs actual is a matter of a swapping comparison
against anything else, like a cobbled foil tape antenna, in one's
given installation position -- not performance in other people's
airplanes.

Fred F.

Sorry, Jos - I haven't got it myself yet! :-(
I'm assuming the Factory will be doing this job for the overseas folks, my
email to the Forum was about tracking the extent of the problem with the PFA
distribution - which is supposed to have gone to all PFA (i.e. UK) fliers
AND builders, but is beginning to look like it has just gone to fliers so
far.
Roger tells me the Mod 70 documentation will be on the Factory web site as
soon as he's fixed a publishing problem.

Yes that is exactly what it does. My engine started cold fine but would
not come up to idle speed. Ran as if only 2 cylinders were firing, very
rough with lots of vibration. It would take several attempts to get it
to run smooth. Once it had fired up once then it was ok for the rest of
the day. I believe it is the kick back that damages the sprag clutch
but the bad starting, going into what the Rotax dealer in the UK
describes as 'sub-idle' it the result.

Can a sprag clutch problem cause rough running after the starter is off
(i.e., sprag clutch not disengaging)? I have been ignoring the sprag
clutch/heavy-duty starter discussion, assuming that it referred only to
kickback and other problems while the starter was actively driving the
engine (problems which we haven't experienced).
Thanks to all who have offered suggestions. We have carefully set the
clutch cables so that both chokes hit their limit stops at the same
time. We have also checked the temperatures of the exhaust pipes (both
by feeling and by EGT reading) after a few seconds of rough running, and
no significant difference was found between the port and starboard
sides.
Today we tried replacing the fuel in the float bowls with fresh auto
gas. No help.
After a few seconds of rough running, the port side carburetor sometimes
overflows fuel into the air box, probably because the float needle gets
shaken off of its seat. Cylinders 2 and 4 are then quickly flooded,
which can be overcome only by opening the throttle far too much. We'll
try starting with the fuel selector off, to see if we can avoid the
flooding.

John, Isn't this a case of designing in failsafe mode? Getting the boost set
in max isn't the end of the world as long as you know about it, since
throttling back should make everything manageable. If you had the wastegate
failure mode giving zero boost then you could be in serious stuck if it
failed on you when you were high up in inhospitable mountain country, or
trying to climb out of somewhere hot, high and heavy. I appreciate that
getting either a surge in power or a drop in power could be pretty
distracting when you are in a circuit situation, but I think I might go for
the surge personally!

Hello Group
I noted that many of you have installed the Bob Archer nav/com and
transponder antenna in your aircraft. I wonder if any have chosen the
Advance
Aircraft
Electronics units which are also available from Spruce. These units are a
bit
more expensive than the Archer units. Worth it?
I would like to hear from you!
On another note. I have uploaded a few Sun N Fun photos in my area of
Europaowners.org. They include a visit to Deans house to check out his
progress.
Thanks in advance for any information on antennas.

<describes as 'sub-idle' >>
Which in another language is torsional resonance. Every engine has this,
especially with a larger flywheel (the prop) coupled by a spring (the face
cam device at he front of the gearbox) to the crank.
This natural resonance usually occurs at sub-cranking speeds and is not
excited by the smooth constant-level torque supplied by the starter motor.
The starting system is usually designed to crank the engine above the
resonant speed. Once the engine starts to fire then, if this is at the
resonant speed, the resonance is massively excited. Resonance absorbs a
vast amount of energy so, even if the engine is weakly firing, it may not be
able to "power through" the resonant band.
So the problem could yet be one of the starter not spinning the engine fast
enough to get through this low speed phase; Or improper adjustment of the
preload of the "dog clutch" which effects the resonant frequency. Or
different prop inertia.

Perhaps another case of "you've been told by the manufacturer that the
engine may stop suddenly without warning". So if it does, its your fault
either if you didn't expect it or didn't control the ensuing situation!!
This culture seems to serve in lieu of a proper fix in the first place.

--> Europa-List message posted by: "Bob Fairall" <b_fairall@fairalls.co.uk>
Correct Jeremy, it's not obvious which a/c it refers to.
If I remember correctly (and bear in mind I am old and senile and my memory
is awful! :-) previous correspondence from the PFA, which arrives in
duplicate owing to my having two Europas, has an a/c reg reference on the
envelope. I will check my bin later to see if I can find the envelope, but
my guess is that this letter comes with reference to flying a/c, kit 71,
G-BXLK.
I must say I am a little uneasy about this mod. Duncan McFadyean has
highlighted a number of aspects that I feel are very pertinent. Whilst being
totally aware that everyone is working towards the common goal of our
(Europa pilots) safety and therefore not wishing to 'rock the boat', I am
planning to write shortly to Francis Donaldson regarding these issues.
Kind regards

--> Europa-List message posted by: "Jeremy Davey" <EuropaFlyer_3@msn.com>
Thanks, Bob :-) For those PFA members who haven't had the letter yet, I'm on
the case with Engineering and will report back.
I should also add that the Europa Club committee are aware of some of the
concerns around the changes, including Duncan's concerns. In defence of the
Factory's new design, I should say that they looked at quite a number of
alternatives, and the one chosen was chosen and tested carefully. For those
not aware, it involves eliminating the support cables to the torque-tube and
using tufnol guides on the pitch-stop support - very similar to something
that has already been done as a mod by at least one builder.
Perhaps it should also be pointed out that the cables are a throwback to the
days when there wasn't a bulkhead there that could be used to constrain the
weights! (G-YURO had two pushrods down the fuse with a bellcrank in the
middle, I understand.)

Jeremy

I am still looking how I can design a trailer for my tri-gear which is good,

to be a closed trailer. On the Europa Club site I couldn't find much info

I should have said that I was with Andy all last week and he said that his
priority on return to work was the tailplane mass balance which he expected
to be available on his return to the UK.
He said that he would also prioritise the fliers first and the builders
second.
I hope this helps you and the factory.

Will someone familiar with Mod 70 please tell this across the ponder what is
involved with the mod, what kind of access in needed and what sort of parts
are involved? Please.

Evening Jeremy
My letter arrived on Saturday morning.
Pete
G-RMAC #109 flying
PS Spoke to the factory this am to order the bits. They said they had
received approximately 70 orders yesterday and lead time was circa 2 weeks.
Obviously they are dealing with the 5 hour change aeroplanes first.

Just a quick question for UK owners (apologies overseas folks!) =96 have you
received a letter from the PFA regarding Mod 70? There is some debate as to
whether any builders have received it =96 certainly at least some of the
fliers have.
Thanks and regards,

Can anyone please advise on how to remove the standard starter from a 912S on an
XS trigear, without removing the engine and replacing with a Heavy Duty?
Thanks

Steve,
You should know the correct method by now:
1. Provide beer and food.
2. Invite local Europa builders and fliers around one evening/ weekend.
3. Provide more beer and food.
4. At end of evening/day suddenly realise job has been done!

| Subject: | Mod 70 and the PFA letter |
--> Europa-List message posted by: "Jeremy Davey" <EuropaFlyer_3@msn.com>
Tom (et al),
This is a mandatory mod that replaces the TP18 tailplane mass balance arm
with a more robust one using thicker-wall tubing. It also replaces the lower
fitting at the aft end with a more robust one that incidentally is easier to
line up with the hole in the crank on the tailplane torque tube due to its
flat sides.
The cables that retain the weights laterally are deleted and replaced by
Tufnol guides on the sides of the pitch stop support.
The mod has come about as a result of an incident with a Europa in the UK
where the threaded portion of the lower fitting failed, effectively
separating the movement of the mass balance arm from the movement of the
tailplane. Fortunately this happened on the ground, not in flight where loss
of control or severe flutter would have been a distinct possibility.
In the UK a restriction on the number of hours that may be flown before the
mod must be fitted is being imposed. This varies by version of Europa as the
components involved have changed slightly over time. Early classics have the
most restrictive number of hours left (5). Later classics and XS models have
the least restrictive number (25).
The Factory are giving priority service to the fliers, early classics first.
They are also open to giving priority to a builder who is about to put the
lid on (note to builders about to put the lid on (like me): don't do it
until you get this mod; it'll be much easier with the lid off!).
Fitting the mod consists of removing the old TP18, support cables and
weights by venturing down the back and using the access holes in the tail.
The new TP18 and Tufnol guides are fitted similarly.
I hope this helps!
Regards,
Jeremy

received approximately 70 orders yesterday and lead time was circa 2 weeks.

Just a quick question for UK owners (apologies overseas folks!) =96 have you
received a letter from the PFA regarding Mod 70? There is some debate as to
whether any builders have received it =96 certainly at least some of the
fliers have.
Thanks and regards,
Jeremy

A useful trick for cold starts in general on the 912s
is to spray diethyl ether (aka cold start spray), about 2-3
seconds worth into the air filter. Works every time, even
at 0-5 degree Farenheit.
Just don't spray it in your face lest you salivate all over you cabin.

We tried that, didn't work. Could be because the port side carb
overflows because its needle/floats are getting shook so bad, fouling
the port side plugs with raw gas. On some start attempts, the raw gas
pours out the ports side airbox drain. The port side needle seals just
fine when the engine is not shaking around so bad.

I remember that I had a similar problem with a BMW which as I am sure you
know has identical looking BING CV carbs. The problem was I seem to
remember that the carb floats no longer floated resulting in oversupply of
gas to the engine.
Dunno whether this is worth a try
