Ever wonder why static systems often start to leak after a couple of years? See the little plastic insert between the two tubes in the photo? It is supposed to be inserted into the end of the tube. Without it, the tubing will eventually start to collapse as seen on the right tube and cause a leak!

The state of Oregon has a new law that mandates using ethanol in all auto fuel, potentially affecting thousands of pilots, especially owners of most of todays Light Sport Aircraft powered by the ubiquitous Rotax 912 engine. It may not be too late to take action against similar legislation that could be brewing in your state; by Dave Martin.

Problem I had with the static lines installed for the altitude hold sensor for the sTek autopilot: apparently the tubes were not ‘approved’ and they got brittle and shattered in the tail area. Took about 15 years from installation, and were not caught during the annual inspection.
