It is near th e edge of the curve downwards and I am hoping there is enough clearance as the engine vibration forces I expect are going to be mostly rotational?. I have taken the outlet pipe out just above the recessed area., If there is a problem later the cowl will have to be modified with a bubble later. Let me know if you find an alternate remedy! Regards Dave Park, Manchester UK t: Europa-List: Silencer position in cowlTo: europa-list@matronics.com Hello all, The silencer (muffler) on my XS / 912 uls (the new oval section silencer) s its forward of the moulded recess in the cowl. The front of the silencer is touching the cowl on the outboard side, forward of the recess. The straigh t outlet pipe from the silencer would exit several cm above the moulded rec ess. The silencer could not move any further back, as it has only a few mm clearance from the bottom attachment of the ring mount. Photo attached. I presume this is a result of having the oval section silencer instead of t he round section one. Have others had this problem, and if so what have you done?

It was heartening for me to see him land on his feet after being screwed like so many others in our community by "he who shall not be named." This new job keeps him pretty busy, but I have noticed he is still happy to see Europaphiles! (We still do a lot of business with Lockwood for Rotax parts, etc!) -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=159851#159851 ________________________________ Message 3 _____________________________________ Time: 03:54:09 PM PST US From: "ALAN YERLY" Subject: Re: Europa-List: Silencer position in cowl Keith, The new mufflers occasionally get very close as yours has. I've had to modify two cowls in the shop. My problem is usually with the motor mount placement and cowl fit. The farther aft the cowl, the closer the exhaust. I have gotten away with moving the cowl to the starboard once but don't count on being that lucky. Take care you don't force it out of alignment and cause an exhaust leak. My solution is to cut a hole and take the intake bump on the port side and extend it to the 914 cowl bulge for the round muffler. It's a half day job over a weekend. Cut the cowl, add foam to contour. Glass the outside, let cure, cut out the foam, and glass the inside. Put firewall material (aluminum/stainless with heat barrier between, sold at Aircraft Spruce for a fortune) then finish.

I'll cut a hole and reglass the cowl. Good to know I haven't made a goof somewhere!
