I just read a report about a wing skin on a Cessna Columbia "disbonding
seven feet during a production acceptance flight test." 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.
