Burnt Cowling, Again…
Has anyone experienced the burning of the lower cowl on the right side of plane due to misaligned exhaust pipe?
I had it and took it to Tampa where they reset the exhaust and replaced the piece of cowling but just 6 hours later of flying and it’s back just as before. Am I the only one and does anyone have any experience with repairing this? -

Since you have serial number 157, either something changed with how your cowling was assembled, or exhaust was built or the technicians are not setting it correctly. There were plenty mis-aligned exhaust pipes on the production line that would get flagged and have production adjust them to alleviate the issue you are having. Once a few happened they knew it could be issue and developed a procedure to not only align them but to check for it this was about 47 airplanes before yours was built so they should have it down by now. Do you have a photo you can post so I can see how far it is misaligned? This should not happen.

Michel you have a different exhaust design and the reason for the burning was due to the safety wire failure on yours. The OP exhaust is the new design which was production implemented from ASN110+ he is due to a failure of being aligned properly.

My aircraft is S/N 161; I have 138 hours on it, and recently I started seeing very slight burning-away of the right lower cowl, at the edge of the rear ventilation opening. See photos below. Anybody else has it at this spot?
