I have in my shop a Sadler vampire. The aileron hinge is riveted directly to the .016 wing skin about 3" behind the rear spar. There is no reinforcement or or stiffeners. When you move or shake an aileron it sets up a waggle in the other aileron leading me to think this thing will flutter the way it is. It is licensed experimental amateur built and as the inspecting A&P there is no way I will let this go this way. I am looking for photos of the aileron bay and hinge or prints. I hate to reverse engineer something that may have been built incorrectly.
The company who bought the design is located in Australia and has since ceased doing business and has the production rights and such for sale.
Any Sadler Builders want to chime in?
Thanks,
Marty
