Title: Possible crack in Exhaust
Post by: CRoss on March 30, 2021, 05:13:20 PM
It looks like I may have a crack where the #6 exhaust stack is welded into the exhaust pipe on my
H-391B.
It has been welded before but doesn't look like a professional job.
Any recommendations for a aircraft exhaust repair shop in case I need one?
Anyone have a left side exhaust assembly for sale?
Thanks

Will 480 exhaust work?

I don't know but will check into it, provided you have some 480 exhaust parts for sale?

What happened to just removing the exhaust manifold, then sending it to a shop like Acorn Welding, letting them evaluate it, then if it's repairable and it usually is, at least in my past experience it has. And then if unrepairable you look at buying a new one.

If I remember correctly from past posting they, Acorn can build an entire new exhaust system if necessary.

I found the previous discussion about exhaust stuff here

Charlie,

I'd recommend going to the H295 exhaust from Knisley Exhaust. You can check out https://knisleyexhaust.com/helio/helio-courier and see that they do Helio stuff. These would be new FAA/PMA parts. At some point welding old exhaust becomes counter productive. Just my opinion.

I've dealt with Acorn on other stuff and they do a great job. They don't make any new parts for the Helio, so they would have to have yours and repair them.
