Our static system had a leak we found and fixed during a static check. Then we noticed the aspens began to wander gernerally lower. We found if we opened alternate static that the altitude corrected to normal and remained steady. I also witnessed this same behavior on a bench test where a tube had become blocked. So if you find a wandering aspen disconnect the static line and see if it stabilizes. If it does you have a clogged tube somewhere. JM2C
