YS stripped muffler thread in the air!
Hello! Yesterday I was flying my YS 91AC engine and when I landed the plane it sounds a little bit weird. I noticed that there was no muffler. When I checked in the pit area, the thread of the muffler stripped while flying. How could this possible happen???
I just oredered a new one from YS service and parts.
Great service YS!!!
