However, I fear I may have an intractable problem with installing it as described in the manual. There is very little clearance between the rudder cable actuating horn on the aft rudder tube and the diagonal tube of the landing gear frame. I was able to slip the card templates in there without much trouble, and after convincing myself that everything fitted, I transferred the (slightly edited) patterns to the stainless steel sheet. However, I cannot persuade the starboard side piece of steel to bend in a way that keeps it in contact with the tube of the landing gear frame, and thus clear of the rudder mechanism, at that critical point. And thats before Ive tried to overlay the bottom piece of steel to form the joint along that diagonal tube. The P-clip that holds the starboard side piece of steel sheet to the lower diagonal tube of the frame forces it to be clear of the tube at the top, and the protruding end of the lower tube keeps the steel sheet away from the tube at the bottom. I suppose theoretically it should be possible to panel-beat the required complex shape but that is above my pay grade. Even so, to get 2 thicknesses in just the right place and not rubbing on the rudder actuating horn might be quite a challenge! Possible solutions that have so far occurred to me are: (1) Make a small piece of stainless sheet to cover just that area of the tube, with a simple cylindrical bend, and somehow join it to the starboard side panel and the lower panel further away so that there is only one thickness of steel at the critical area. Anyone in UK done this? (2) Try to make a complete new firewall in a slightly different location, as suggested in the Europa Club Hints & Tips - originally posted by by Graham Clarke on 9 Dec 1995. He suggests putting the firewall in the plane of the vertical members of the landing gear frame, so that is just in front of the bungees and does not interfere with the rudder mechanism. Obviously it would need to be made in at least 2 parts, but it looks as though it would be simpler to do that the pyramidal design in the manual. Has anyone done this under LAA jurisdiction? Is there a mod number? (3) Does Graham Singletons phenolic firewall solve this problem? And if so, is it still available? [Hello Graham, are you out there?] Does anyone else have another idea? I dont feel like ripping out the footrests to re-position the rudder tubes further forward, or removing the landing gear frame to re-position it further aft!

Answer to number 3, No Graham's firewall isn't available anymore unfortunately Read this topic online here: http://forums.matronics.com/viewtopic.php?p=452800#452800 ________________________________ Message 3 _____________________________________ Time: 05:49:06 PM PST US From: "Bob Harrison" Subject: RE: Europa-List: firewall problem Hi! Rowland. I overcut the slots in the stainless sheet and over covered the slots with fire sleeve rubber and cut the rubber to accommodate the rudder actuating lever/clevises/springs and cable to pass through it as necessary. (not yet tested with fire in the engine compartment !!!)
