Hello All,
Just to let you know that we now have a full house for the seminar,
advertised in Europa Flyer recently, in Frimley, UK, on 11/12 march. If you
have been in touch with me up to today, you are coming and I will send
details week after next; if you have not been able to book yet, I'm afraid
there is no more room available.
Thanks,
dave

Has anyone got a drawing for the fitting of door locks to a Europa XS.

I am intrigued by the discussion - particularly the mental picture of 2
pumps in Series or Parallel. There seems a discrepancy in some of ther
discussions in the true meanings.
If it were truly Series, what plugs the first will plug the second pump, so
I conclude (from the electric alanogy) that the present setup is
Series-parallel of a kind.
If both filters come first and are in parallel, all parts downstream should
be clean. Because they are parallel, as one begins to block, the other takes
on the whole task - so regular inspection should satisfy any precautionary
need. But my pumproom is at the rear, so I figure I need a shutoff valve
upstream of the filters so I can open them. Then, filter 1 leads to check
valve 1 and filter 2 leads to Pump 1, they combine into one line and split
again (tee) one branch to check valve 2, and the second branch to Pump 2.
They recombine into one line (which in my case leads to a lowest Gascolator
and off to the engine .
Thus (if you sketch this out corrctly), the two pumps are clearly one after
the other (series), but if any component plugs, another will feed the fuel
through an alternate line (parallel). In any case, I'm hoping the flow
pressure is not excessive, either with all bits working, or when one branch
is plugged.
I also have the excess fuel returning under the starboard sill to
the fuel filler entry on the tank. Is there any foaming involved in the
overflow fuel? If there is I'm hoping it dissipates on top of both tanks
when fuel is above the saddle, and on top of reserve when sucking from the
bottom.
I realise I'm not designing for Mars, but hope I am on track to a secure
fuel transfer plot.
Flames and flowers eagerly anticipated.

--> Europa-List message posted by: "GTPowell" <georgepowell@hotmail.com>
I've been looking at corrosion protection substances, and Aircraft Spruce has something
called PreKote, which apparently is widely used by the US Air Force,
Boeing, etc. It is not a chromate or conversion process, does not require acid
etches or solvent washes, and can be used on a variety of surfaces. The price
is reasonable, too.
Anyone have any experience with this? Comments would be appreciated.

Hi Ron,
Received a shredded envelope with "hand stamp only" on it.
I just hope they're still trying to figure out where that spring goes in the sorting
stamping machine. : )
Thanks for the valiant attempt to thwart the US post office,

A question for those who have gone before in relation to the leg covers.
They are supplied longer than required and are tapered to match the legs.
Did you trim them to length from the top? bottom? or both ends?

Hi Steve
Ron sent me one and some wire. I made another as I wanted an increased
diameter so I could put it over a spacer. I am happy to send you the one he
made.

--> Europa-List message posted by: Andrew Sarangan <asarangan@yahoo.com>
Fred
Thanks for your comments about the LED nav light installation.
Regarding access panels, I did not need them for my installation. The
whole assembly comes off easily. You take the light covers off (4
screws), then the reflector (another 4 screws), and you will you have
everything in your hands. None of these parts are permanently bonded to
the aircraft.
Although I like CreativAir's design, I would have liked to see more
performance data of their product. Their documentation says the light
output exceeds the FAA spec by 10%. Presumably that was measured
without the plastic light covers. Since the plastic covers do absorb
and distort the radiation, the 10% margin was a bit too close. Most
importantly, LEDs lose illuminance with age. Their lifetime is defined
not by mean-time-before-failure, but by the time it takes to lose 50%
illumination. This aging process is accelerated by higher junction
temperatures. Since Creativ's design does not employ a heatsink, I
suspect the aging process may be faster than normal. Instead of
focusing on lower current draw, I wanted to focus on greater
illumination. The current draw in my design is 4 times greater than
CreativAir, so it is not surprising that it delivers 4x time more
illumination. However, LED performance doesn't scale that way. You
can't supply 4x current into any LED and expect 4x illumination. The
ultimate performance is limited by thermal considerations more than
anything else.

| Subject: | RE: 914 fuel pumps |
--> Europa-List message posted by: "josok" <josok-e@ukolo.fi>
Hi Ferg,
Serial or parallel or semi <grin> Anyhow in the setup as per old and new Europa
engine etc. one filter is connected to the reserve outlet and the other to the
main. That makes sense, because if one filter would block, you would be able
to select another way to go for the fuel. So up to here there is no difference
between series and parallel. To make things more complicated many others opted
to forget the filters and mesh on the tank-outlets and install one gascolator.
The filter element in there has a far larger capacity, and the particles
it let pass are smaller then the jets in the carbs.
Then the pumps, the new advice is to put them in series. That IS series, not parallel.
But PARALLEL to the pumps are one way valves. Maybe this causes the misunderstanding?
If one pump stops working and would pass fuel in the wrong direction
or not at all, the other one would all by itself, via the one-way valve
of the other pump, be able to supply all the fuel you would ever need. Without
the check valves on the parallel system, there is a situation possible where
the fuel from one pump would return through a defect other one. With parallel
pumps and the check valves in series with the pumps, that problem does not
exist. I just do not like to swirl that will happen with a double, never needed
flow.
Fuel pressure with both pumps running in series is double of the parallel system.
Similar to the electrical analog. Fuel flow is double of the serial configuration.
Both, pressure and quantity is more then your engine can ever eat. Fuel
pressure in the crab bowls is regulated by: a regulator, which on the 914 gets
it's information from the air-box pressure. Fuel return flow is just a factor
of the quantity, somewhere i seem to remember it to be 40 to 45 liters with
one pump on.
Since i will be monitoring fuel flow, there will be one sensor for forward and
one for backward flowing fuel. There will be a press and hold contact to block
the pulses from the back flow sensor. In my run-up checks i will press that button,
and check that i have +40 liter flow while switching from one pump off
and other on.
Hope it helps,
Jos Okhuijsen

"I am really learning about fuel pumps and pressures etc (I think) and wonder
if anyone can comment on the problem I have with getting a smooth running
engine at RPM below about 3600 on my 914. Could it be overmuch fuel pressure
and carb flooding with both pumps on in my parallel system?"
Patrick, having recently attended a class on the 914 I would suggest pneumatically
balancing the carbs. This has the single greatest impact on a smooth running
engine. Also, remember the fuel pressure at the carbs is a function of airbox
pressure and is set by the fuel pressure regulator, therefore, having the
pumps in parallel would not cause flooding. I have been using the parallel system
on my 914 for the last three years without issue. Almost all the 300 hours
have been at or above 12,500 ft MSL.
