Fuel hoses and o-rings in the Europa FirewallForward kit should be checked separately for alcohol effect and replaced if needed with airworthy replacements. Ira N224XS nearly 100hrs

    --> Europa-List message posted by: "Fergus Kyle" <VE3LVO@rac.ca> Ira! Thank you for that. It puts me more at ease. The lecturer claimed E10 to be destructive of aluminum alloy, unless treated specially (which he says the car-makers have done for years, as some companies have been sneaking ethanol in in small amounts for that time). Am not sure whether the alu lines from Aircraft Spruce are such.......... The idea of changing is an ordeal I don't relish. Any more heartenng info gleefully welcomed. Ferg PS Cool engines, increased aeration with height, detonation resistance and icing qualities were mentioned. ----- Original Message ----- From: <irampil@notes.cc.sunysb.edu> Subject: Europa-List: Anguish over Ethanol | --> Europa-List message posted by: irampil@notes.cc.sunysb.edu | | (Repost)From the Chief Technical Officer at Kodiak at Oshkosk2004: | There is not part of a rotax 900 series engine harmed by gasohol. | Gasohol is to be avoided in lycs and contis because they still use cork | gaskets which will dissolve.

    --> Europa-List message posted by: Paul Stewart <europa@pstewart.f2s.com> Brian I have missed all the discussion about this. There are some picks at: http://www.europaowners.org/modules.php?set_albumName=album58&op=modload&name=gallery&file=index&include=view_album.php of my fuel installation which includes a hatch under the gascolator in the rear baggage bay. It is secured by the same quick release catch as the oil dipstick hatch. It is PFA approved. Not that far away near Derby if you ever want to have a look. Regards Paul

    Subject: Mass Balance Arm Cable Attach
    --> Europa-List message posted by: Tony Renshaw <tonyrenshaw@optusnet.com.au> Gidday, I am studying my tailplane setup and wondering if it is normal to have the cables that stabilise the mass balance arm wrapped around the white plastic tubes in such a fashion that the looping creates an overlap on the back edge of the plastic sleeve, held in position under tension only by the small protrudence of the pin base? Now I am unsure which way the pins should be, but I have decided that I want the heads of my pins forwards, as I have little holes adjacent in the rear tail bulkhead that will be accessible from another hole in the sternpost, so that I can use a long rod to tap them out again in the future, plus also drive them home from within the tail. This is probably the normal way anyway, to have the heads facing forwards, but I haven't reviewed the manual on this as I have my own intentions anyway. So, I do however have the problem that if the cable was to flex on one side, it could enable the slack side to slip inboard over the tail of the pin. Whether this would ever happen is probably the question to ask, as it would mean that the other cable under tension would have to stretch to allow the other to go slack. I suppose this then begs another question which is how tight to make these cables. I have turnbuckles, so I can tweak them until they are tight as I like. Is there any advice as to how tight is enough an not too much. I suppose the tighter the less likelihood of further stretching which is what I am trying to negate with a lateral load, which is of itself a questionable load anyway. How am I going to fly my plane in such a fashion that I get a lateral load of sufficient strength that it allows one cable to stretch and the other to go slack and slip over the tail of the pin. My aircraft probably would break elsewhere. I am simply seeing the length of my pins as being apparently inadaquate to also act as a containment
