During a post-flight inspection, I found that the outboard Cyl #3 spring retainer "clip" has broken off of the exhaust tube. It was in service for 150 hours.
Upon inspection, I found that the spring was successfully captured by the safety wire (and was in good condition). One clip weldment point looked to be non-existant.. as if it wasn't welded onto the tube at all. The other weldment point looked to have given way to fatigue and left a small hole in the tube.
Has anyone else had this happen? Thoughts about patching the hole, then welding on a new clip and calling it a day? Any concerned about the longevity of that solution due to the heat cycling? It seems the newer tubes have their clips welded on the top and bottom sides..rather than what looks to be a tack weld on the top (see 3rd photo). Waiting to hear from Support.
