Well, you probably thought this was going to be about the fuel gauge, but that comes soon. I haven’t received the invoice yet and I like to have full info before posting.
Nope, this one is about the shiny new muffler on N194SP (and four other WVFC aircraft). It appears that Aerospace Welding, the maker of the muffler on the 172 SP did a poor job of making the original muffler. Bad enough to kick off AD 2018-02-04. Although an inspection would be sufficient to hold off replacing the muffler for up to a year, every muffler that’s been inspected has failed. Mine was just straight replaced. New Inconel muffler has been installed!
$1200 covered that. 4 hours labor and a $650 muffler.
