Subject: | Fuel Pressure Sender |
John,
The branch-off to the fuel pressure sender should be as close to the
carburetors as reasonably possible, as the purpose is to measure the
"in-pressure" to the carbs. One easy place is where the fuel line to the
right side carb branches off. Here is a T in your installation, I assume.
Replace this T with an X (a four-way cross), and connect the sender to the
fourth outlet of this cross.
If the sender at present is connected to the tank return line after the
restrictor (I assume you have a 912/912S), no wonder your EIS does not
register any pressure. The restrictor causes a significant pressure drop.
The restrictor sits inside the return line, just after it branches off from
the fuel line going to the left carb, if done according the Builder's
Manual, and is not visible from the outside.

Thanks for the info on the position of the fuel pressure sender. I'll
reposition it.
In the EIS manual there are 4 different scales - the 0 to 10 psi
appears OK and like wise the resister 200 ohms and Aux SF 250 and
AuxOff 47.
Just thinking what range is working in your Europa?

Andrew. The standard design works well and is easy to produce & make
reasonably 'crud-tight' - which is what it is there for.

John,
I have a VDO pressure sender and the Grand Rapids EIS, but I do not have the
settings readily available.
0 to 10 psi is a good range.

Subject: | Re: Monowheel bulkhead |
The reason for my confusion is, the suggested location of the plywood
would cut halfway through the fuel valve access hole on the starboard
side of the tunnel (page 17-2 of the manual). Since the fuel valve
has to be aft of this plywood bulkhead, I can't see how this setup
would work without moving the plywood further forward, or making it
conform to the wheel well curvature.

Subject: | Mysterious vibration on Europa Tri Gear |
Aircaft: Europa Tri Gear
Engine: Rotax 912 UL
Propeller: Airmaster 322
Help! I would welcome any advice or suggestions regarding a problem which is afflicting
my aircraft. It has developed a strange vibration/resonance which occurs
after establishing the cruise. For example, after a normal take off and climb
I set the prop to Cruise, reduce the MFP to 26 which gives approx. 100Kts
at an indicated 5200 RPM. Everything appears normal at this stage. If I increase
the cruise setting to 27, or greater, everything remains smooth, but reducing
back to 26 re-introduces the vibration (which is noticeable unless the throttle
is reduced almost to idle), which although it does not shake the aircraft
to pieces, is most noticeable. The vibration remains through reduced throttle
settings and can only be cleared temporarily by adjusting prop pitch to use
a higher RPM and power settings.
Initially I was convinced it was a propeller issue, but detailed checks have so
far failed to highlight any problem. Airmaster are convinced it is not their
propeller at fault but gave me several thing to check, all of which I have done.
Europa suggested the prop carbon brushes and tracking should be cleaned which
I have done. For a while I thought this might have cleared the fault, but it
returned after 55 mins of flight. Interestingly At the same time as I had cleaned
the tracking I had removed the whole exhaust system for inspection. I could
not find anything wrong, no holes, or loose pipes so I refitted it and lock
wired everything.
I have inspected the carburettors, replaced the rubber mountings and balanced the
system and everything appears to be normal.
I have to admit I am at a loss to know what to check next. It may be related to
something that was removed and refitted during the exhaust inspection, but I
cannot find anything obvious and I do not understand why the problem is not apparent
as soon as cruise power is applied.
I would welcome any thoughts on this matter as it is driving me mad!

Hi Gordon
A few thoughts:
**Although you stated that you have balanced the carbs, did you check that they
are being opened the same throughout the throttle range? Do you have a kinked
or otherwise compromised set of cables? Did you try balancing at around the throttle
position you are having a problem?
**Are your carb float bowl vents in good condition and both plumbed to approx.
ambient pressure?
**If you switch from both to left then right mag, is there a change?
**I am not sure, did you check the tracking of the blades? Did you measure that
the blades are the same pitch, especially at the approx pitch where you are having
vibrations?
**Did you ever dynamic balance the blades?
**Did you do the mod to undercarriage mounting frame? Is it or the motor mount
cracked? Is the engine mounting bolts (Binx nuts) properly torqued? Are the motor
mounts in OK condition?
**Is the choke (enriching circuit) cables completely closing the arms?
**Is there a leak in the balancing tube?
**When was the last time you replaced the spark plugs? Is there a chance you may
have wires that got mixed up?
**Is the spinner tight with screws tight and no cracks and does it track true?
Is the backing plate cracked? Did you by chance install different hardware where
on the spinner, back plate or other is causing the prop to be out of balance?
** How many hours on your gearbox since it was checked? Do you have a slipper clutch?
Do you use 100LL a lot? do you have a problem starting?
Have a look through here, especially vibration:

Gordon,
Just for giggles, clean and re-lubricate the throttle cables and insure
that there is no binding in the system, check the return springs, that
they are plenty strong, then re-balance the carbs at the exact rpm the
vibration is occurring. Also, be very sure that no exhaust gas is
making it's way up to the carb bowl area. This should rule out a leaky
exhaust system (causing vapor lock) and any carb balance issue. The
very design of the throttle cable system causes the carbs to go slightly
in and out of sync, as the throttle in manipulated, due to the cables
changing length, slightly, in relation to each other. Nothing to lose
but time and everything to gain...
