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 ________________________________ Message 2 _____________________________________ Time: 07:50:29 AM PST US From: "Arthur Orchard" Subject: Europa-List: Door locks --> Europa-List message posted by: "Arthur Orchard" Has anyone got a drawing for the fitting of door locks to a Europa XS. Thanks Arthur ________________________________ Message 3 _____________________________________ Time: 08:07:32 AM PST US From: "Fergus Kyle" Subject: Europa-List: 914 fuel pumps --> Europa-List message posted by: "Fergus Kyle" 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.

From: "GTPowell" --> Europa-List message posted by: "GTPowell" 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.

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. --- Fred Klein wrote: > --> Europa-List message posted by: Fred Klein > > > Andrew...looks like an outstanding installation.

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 ---------------- ________________________________ Message 13 ____________________________________ Time: 01:31:29 PM PST US From: BEBERRY@aol.com Subject: Re: Europa-List: Trigear speed kit question --> Europa-List message posted by: BEBERRY@aol.com SIMON - I trimmed mine at the top as you have to cut an angle to fit the shape of the fuselage.

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. Erich Trombley Try Juno Platinum for Free!
