    On the other hand, there are many Rotax engines flying fine every day with E10. Rotax itself has said it is OK for the 900 series engines. For the standard Europa-supplied tank, E10 has no obvious effect, not in my A224 which has been flying more than 5 years with nearly exclusively E10. At my fifth annual inspection, per recommendations, I replaced all of my fuel hose. There was no sign of interior degradation, but I replaced the Gates R5 hose with R7. If I had been particularly concerned I would have selected Aeroquip 666 teflon/carbon hose which has an infinite service life. It would have required however replacing all the fuel fittings from barbs to AN fittings from the tank to the engine. If E10 is the only mogas you can obtain, it is still better for the engine than leaded AVGas -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=277323#277323

    Hi! Paddy I will be making an attempt to get there .

If the fog clears in time, I hope to make Turweston ( hard runway, voucher in Flyer ) on Sunday 13th. I usually say 1200ish, but I'll get there when I can! All the best, Paddy Paddy Clarke Europa G-KIMM

    An extremely detailed research programme into MOGAS and related subjects has been commissioned by EASA. Barry Plumb of Light Aircraft Association (the UK homebuilders and GA pilots' association) is a member of the panel undertaking this research. The project is very nearly finished, and it will then be published on the EASA website. Barry will prepare a pr=E9cis of this report, and when that has been put onto the LAA website, I will advise you all of the link to it. David

    Subject: Europa pitot-static probe warning
    Today I made a disturbing discovery. Some time ago I checked that my pitot static systems were leak free. Pitot would hold pressure over a few days, static, with much more instruments coupled to it, would hold it over a few hours. I tested this with a syringe connected to the tubes that went to the pitot- static probe. So, with much confidence I went today to the official mandatory pitot static test. To my dismay, the static system appeared to have a massive leak, with the altimeter set to 1000 feet, it would go down to 0 within a few seconds, pegging the VSI in the corner. Tracing down the leak, it didn't take long before I discovered that the static probe itself was the culprit! (I had not included it in my own test because it was sort of difficult to connect a tube to it, and it was of metal after all so I somehow trusted that this thing would be ok). The static probe consists of a tube with an inner tube inserted into it to allow a standard diameter hose to be fit. This was where the leak was: between the two tubes. When I tried to disconnect my test hose from the tube, suddenly the inner tube came out of the probe! It is unclear if and how the inner tube was secured to the outer tube. I can't see traces of solder or welds, nor from any type of glue. As this is a piece of equipment originally delivered by Europa with my kit, it may well be possible that other pitot-static probes have the same problem. It might go unnoticed for a while, and maybe after a while it starts leaking. If that happens, the static system will now be fed with air from the inside of the wing, and this pressure might be far from neutral. So, if you a bored, you might screw off the probe and have a good look at it, and maybe as a precaution, use some sealant over the joint between the two tubes. Frans

    Subject: 309 Stainless Steel tube
    From: Paul McAllister <paul.the.aviator@gmail.com>
    Hi All, I was wondering if anyone while they have been traversing the vast space of the internet has found a source for 309 stainless steel tube. I need about 3 feet of 1.5" tube, or even better an OD of 40mm Jason, I have put you on copy because I know you manufacture a nice exhaust/turbo system for the 914 and you might be using SS 309. Thanks, Paul

    Paul, onlinemetals.com has 304 SS & 316 SS... burnsstainless.com has 304 SS & 321 SS... what's special about 309?

    Hi Paul "I was wondering if anyone while they have been traversing the vast space of the internet has found a source for 309 stainless steel tube." I first question if you really need 309?? I know Rotax is now using 309 on new style exhaust, they used to use something else. Is your exhaust 309?? Old style is said would be lucky to last one TBO, 309 is expected to last at least a few from what I understand. Anyway if you are just wanting to make a new exhaust pipe I think 304 should be fine. You can weld 304 to 309 with 308L welding rod, www.mcmaster has both. If you want better heat resistance they sell 316 tubing in 1.5", I am pretty certain you could weld 316 to 309 with 316 rod they sell, but not certain 100% on that so check , McMaster sell both. 321 stainless is used in aeroplane exhausts, better for temp than 304, I didn't check if McMaster sells, but Spruce sells, not sure if you can weld 321 to 309 and what rod if you can but if you just need it for pipe which would be overkill but better for temp than 304. I have looked for 309, not too successful, however McMaster sells a 1.5" 3' long rod, you could knock yourself out and bore it out, probably would need to cut it down to bite sized pieces and weld it back together after you made a pile of chips. You may want to consult with an aviation muffler/exhaust specialist. Have a look in Trade a plane, think Dawley is one that has a good reputation. I am installing a mixture control on my 914, to monitor how I am doing. I will be welding a 304 stainless bung to my 309 muffler using 308L rod. The bung will hold a O2 sensor and drive a mixture monitor which I will use in addition to two EGTs. I researched in past and 308L is a good choice for welding 304 to 309. Off topic a bit but will stand on my soapbox and mention more ethanol is needed compared to gasoline to achieve proper mixture. Thus E10 will run leaner than gasoline with no alcohol with same tuned type 64 Bing carb. Especial on a 914 that you modified the intake track (inter-cooler is just such a modification) when you are making some BTUs you want to be sure you are rich enough. Rotax wants you to measure carbon monoxide on each cylinder when making war emergency power (115%). They issued a bulletin a while ago that is still in effect to make sure you are not lean. I will throw a dart and say they will probably bring this up again in a service bulletin when using E10 in the future. I like Bing type 64 carbs, if anything I want to run a tad bit rich when making some BTUs, and OK to lean when you are not. Off soapbox. Good luck Ron Parigoris BTW if you are mutilating your exhaust and want to fool with a mixture monitor, I am using Split Second ARM-1 http://www.splitsec.com/ Nice small unit driven by a O2 sensor. Since you are not driving a computer that is using info to adjust mixture, even with 100LL use sender will begin to slow down and yet still be fine for monitor. Dart throw is 100 to 200 hours with 100% 100LL. There is a routine upon start up that will tell you when it is time to replace sender Read this topic online here: http://forums.matronics.com/viewtopic.php?p=277388#277388

    Not sure if this helps but ACS has 321 stainless which is good for temps of 1500f, if that is high enough they sell by the foot -----Original Message----- From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com]On Behalf Of Paul McAllister Sent: Sunday, December 13, 2009 2:09 PM To: europa-list@matronics.com; jason Parker Subject: Europa-List: 309 Stainless Steel tube Hi All, I was wondering if anyone while they have been traversing the vast space of the internet has found a source for 309 stainless steel tube.
