That’s not too bad at all to my eye.

Mine looked even better until I undid the six retaining bolts to remove the lower cowl last week, whereupon the middle section of the duct disintegrated into a pile of black rubber flakes and a bunch of gray dust..

How bad of shape is your current one?  I replaced mine 2 years ago at annual since TopGun had one in stock and I knew they were hard to get.

You are welcome to my old one but it is not perfect (otherwise I wouldn't have replaced it!)

If you are interested I can take some pictures of my old one

thanks Mike that would be great that way I won’t miss summer flying!

I am new here so not sure how this chat group works but I learn fast

This along with some minor rtv repairs could be a good solution.  Most mechanics are ok with some minor repairs as turbo described above.  Just don’t get into the duct tape and baling wire as it is a critical part.

Welcome!  At first, I couldn't figure why you had quoted MikeOH.  Turns out you had written your response in-line with the quoted text from his post, but it was far enough down that it is hidden by default.  Better to select a few words or a sentence from the post you want to respond to, and then click on the "Qute Selection" button that pops up.  That will open up a response box that you can type into.  This clearly identifies the person and the idea you are responding to, and it sends a notification to the poster you quoted that there has been a response -- otherwise the poster you are responding to gets no notification.

Perfect thanks my learning curve is vertical right w

Fix that one with some tank sealant and fiberglass cloth

Hi all, lurking since a while.....Ok. All those ducts start disintegrating from the same points. I think that the damage comes from shaking of the engine during starting or shutdown. Does anyone know how much axial (in the direction of flight) movement there is during flight operation? I'm just playing with another solution....
