Fuel Tank - Now what? - Fixed It
When I balloon tested my left tank the ballon stayed up for over a day before I took it off. When I tested my right tank Friday I discovered a leak in one corner on the outboard rib which I repaired. I tested the tank again yesterday with a balloon and it kept its pressure for over three hours and then completely deflated (I was working on my flaps and didn't notice it going down). I put on another balloon and sprayed the rivet lines and end ribs and couldn't find any leaks. I checked my marks and it stayed inflated for over three hours keeping the size. When I checked the balloon this morning it had deflated again but was still holding air.
I don't know if I am getting a slow leak from where the balloon is attached on the vent or maybe I have a slow leak in a rivet or rib. Now what?
Thanks,
