STC for Muffler
Posted: Thu Jul 19, 2018 6:21 pm
Okay, the Centurion engine muffler situation is foolish. They had five ADs and they replaced them all with a single AD that mandates a 25hr inspection and, as far as my mechanic and I can figure, it means the new bracket lasts 40hrs before it cracks. It's a $30 part, so maybe that's not a big deal, but getting into the shop for the inspection every 25hrs is a pain with a plane that's meant to go 100hrs between oil changes.
On the NG it is solved with a baffling box that absorbs the vibration of the engine. Why Technify hasn't copied this, we don't know.
My mechanic thinks that he could get the box from the manufacturer (it's not Technify manufactured but a standard automobile item). Install a pair on my plane for six months (I'd be experimental during that window), and get an STC letter from the local FSDO. Then we could recover any costs by selling the letter for a nominal fee.
Other than the supercharging effort, has anyone been involved in anything of this nature? It seems very straightforward.
Anyone know anyone inside Continental that could say whether THEY are about to release an STC themselves to fix this glaring example of poor engineering?
