You forgot old glue joints. I have had a plane for 20 years. It died today. 9/23/04. Had 8 flights today and on the last one I had landed ALREADY and was too close to the side of the strip with tall grass and the wing hit the grass and ripped off the wings and in the process broke apart most of the glue joints in the body. Bulkheads flewout every where. Death of a good plane.
