Yesterday I had the cowl off of my RV-12 to install new exhaust pipes as per Service Bulletin 00005. I found both exhaust pipes on the left side had worked their way out and were sitting up on the muffler socket. I have attached a picture.
This RV-12 is new to me. I had some work done on it before I picked it up including new stainless steel exhaust springs installed when replacing a broken exhaust spring. That was only about 5 hours ago. Now one of the new springs has also broken and both tubes are out.
So what gives? I am wondering if this means I have excessive vibration or some other problem. Vibration doesn't seem excessive but like I said, this -12 is new to me so I don't have a lot of experience to judge by.
