Russowens Posted October 13, 2017 Report Share Posted October 13, 2017 My plane: Phoenix #17 Engine hours: about 420 About a week ago, I was cleaning the belly of my Phoenix and took a closer than usual look at my exhaust pipe. Right at the place where the exhaust pipe makes a change in direction (out in the airflow and in plain sight) was a crack in the exhaust pipe. The crack generally followed the weld, but also went across the weld and continued on the other side of the weld. The length of the crack continued for a bit more than halfway around the exhaust pipe. I'm a little embarrassed that I can't say when the crack first started, but I didn't notice it until a week ago. It was easy to remove the muffler, cabin heater, exhaust pipe combination and have the stainless steel pipe TIG welded. Reinstalling the assembly was also relatively easy, but I'm glad I took photos of the cabin heater cable setup before disassembly.
