From: "John Wighton" The problem with the (crappy) glass/plastic filters is that 22 micron screen is way too small - a stainless screen will catch the same gunk and non-detrimental particles as the original. I proposed a MOD for Andair filters - he has now created a part for 1/4" fuel lines. Andy Draper was taking this up at the LAA, l believe. see www.andair.co.uk/product/cleanable-fuel-filter-fx250-e/ Cleanable Fuel Filter for 1/4" Fuel lines FX250-E 47.25 They have a 62 micron filter which is within the 100 micron specified by Rotax. I had a stoppage due to the pesky glass/plastic filters and will NEVER use them again. They are for lawn mowers (etc). -------- John Wighton Europa XS trigear G-IPOD Read this topic online here: http://forums.matronics.com/viewtopic.php?p=478680#478680 ________________________________ Message 2 _____________________________________ Time: 12:53:57 AM PST US Subject: Europa-List: Re: iLevil & Replacement Fuel Feed From: "John Wighton" Installation in an empty aircraft opens up plenty of possibilities. However, throw in some luggage, a fuel can (metal mandatory at MOGAS stations above 10lt), folding chair, rudder lock (in my case metallic), etc. The results are then somewhat different. Example - a compass that deviates by 20-30 degs if it is fitted immediately beneath the baggage floor. Recommendation is to fit it as far away as possible from the baggage area. In the roof maybe the best place. I think l would go aft of the D-panel depending on your antenna arrangement. -------- John Wighton Europa XS trigear G-IPOD Read this topic online here: http://forums.matronics.com/viewtopic.php?p=478681#478681 ________________________________ Message 3 _____________________________________ Time: 01:09:29 AM PST US Subject: Europa-List: Re: Brass gauze fuel filter elements? From: "clivesutton" Hi John, Thanks for your informative post and for filling in some detail on the Rotax fuel filtration requirement. I understand (from Andy) that part of the problem with the Sytec elements is the warp and weft nature of the filter - that the 22 micron 'holes' can vary in size and that once a small goat gets between the fibres a contaminant can actually enlarge the apeture as well as trap it. I have actually not had any problems with mine though (being a bit anal in my approach) i do visually check for contaminant buildup before most flights, have the second filter option installed, and have the Rotax fuel pressure gauge and a separate fuel flow meter fitted in my panel - to enable real-time monitoring of any flow deterioration. For those who don't want the gascolator or 35 filter option you mention i'm going to plough on a bit further to see what's possible with an improved element, and at what cost. Perhaps i should survey and see how many people use the factory Sytec solution. I think it's most of us - but maybe not . . .? Clive -------- Compound interest is the eighth wonder of the world.

From: "John Wighton" Clive, I understand what you are saying - but we don't have transparent, inspectable oil filters. The reason - because we know the design of the filter is good and we don't have to worry about it (too much). Same strategy with the fuel filters. Following the stoppage (recovered in the air by switching quickly to the reserve line, l had actually read the AAIB report of the fatal Europa accident the night before), l literally flew from field to field for 12 months waiting for it to stop. I not only looked at but unscrewed and checked for green slime every flight. A necessary precaution due to the bad design. Now l pull the Andair filters apart annually. Most importantly l no longer worry about fuel starvation due to blocked filters. Giving me capacity to worry about all the other stuff!! If you get to the same state with (fragile) glass filter bodies and super-duper stainless gauze then the jobs a good'un. -------- John Wighton Europa XS trigear G-IPOD Read this topic online here: http://forums.matronics.com/viewtopic.php?p=478685#478685 ________________________________ Message 5 _____________________________________ Time: 04:20:57 AM PST US Subject: Europa-List: Re: iLevil & Replacement Fuel Feed From: "h&jeuropa" We originally located our magnetometer aft of the D panel at the side near the fuselage top and bottom joint. We had a lot of problems due to the movement of the tailplane counterweight, even though it is nearly 2 feet away. We eventually located it overhead between the doors and have had no further problems. In this location, baggage and metal items in the baggage bay do not influence it either.

From: "h&jeuropa" We had one of the Europa supplied Purulator filters come apart on its own! It was fitted with the spring per the factory but the metal of the threaded rod was of such poor quality that the threads were not strong enough to hold the ends on. Today we use a simple automotive in line fuel filter.

There is a lot of metal back there. I am involved in major MOD (to special missions configuration) of a number of aircraft. They range from UAV types up to Global Express 6000. One of the interesting aspects for me (being predominantly a structures/stress guy) is the extraordinary efforts gone to by the systems/avionics guys to minimise interference (or maximise performance) of all the clever electronics. Their kit is different but the problems are similar (and more expensive to fix). Compliance to regulatory and client specific requirements is mandatory. The EMC and EMI studies are therefore very necessary - but utilise software and test equipment that we could also apply to our aeroplanes (which are rapidly becoming way more complex than recent airliners and military aircraft). Food for thought. -------- John Wighton Europa XS trigear G-IPOD Read this topic online here: http://forums.matronics.com/viewtopic.php?p=478690#478690 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/europa-list Browse Digests http://www.matronics.com/digest/europa-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
