The FAA is issuing an AD and looking into if "unsafe condition is likely to exist in other products of the same type of design." As I was building my Glasair I needed to disbond my rudder skins because of a mistake I made and was surprised how easily they came apart and hoped my wing skins would fair better. I had a friend that manufactured glass sail boats help me and he sanded my spars and wing skins with 80 grit paper and washed them with acetone before laminating them together. During the construction he would comment on the parts and would ask in his thick German accent; ""Vat did Glasair design..a tank?!!" When I incorrectly laminated a foot long fiber glass right angle to the inside of a fuselage skin I at first tried to pop it off using a hammer and chisel and couldn't and ended spending a long time sawing it off with a hack saw blade. Four years later when my nose gear sheared off the plane as I was landing on a sandy soil threshold causing my right wing dug into the ground and cart wheeling the plane. My concern was disbonding of the wing skins. I tapped the entire length of the spar with a coin and couldn't detect any disbonding. My German fiberglass expert friend advised that if my skins hadn't rippled there wouldn't be any disbonding. All of my damage was at the point of contact. My G-Meter was pegged at 14G's and I couldn't decide if the wing actually stood 14 G's or if that was the shock of the nose digging into the ground. Bob Heredeen pulled very high G's in both his Glasair 2 and 3 for years. Also Glasair uses a different resin than Lancair that may be stronger. I completed my plane in the spring of 1991 and had the nose wheel assembly part company in 1996. After I repaired my plane I pulled my chute from my Pitt's S1S and flew up to 6,000 feet and did aerobatics to test my wings and pulled close to six G's. I never bailed out of a plane before and hoped I wouldn't have to. I would also add that there has never been an in flight structural failure of a Glasair. My hope is that the FAA doesn't jump the gun and issue an AD on Glasair's and that they first contact the company and retrieve some data. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message glasair-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Glasair-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/glasair-list Browse Digests http://www.matronics.com/digest/glasair-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
