Chuck, Sorry to hear you are having problems with delamination. My own
plane is 30 years old and kit number 286. It was the 35th glasair to fly and
is a tail dragger.
On the early kits, five pound foam was used to construct the firewall and it
had a failure problem on some planes. Mine is holding up ok. On the wing
walk area, some failure was experienced and a fix for existing kits was
recommended that has served well
As far as I know, these are the only fleet wide delamination problems. I
have found one other small delamination problem that was my fault. I turned
the exhaust back into the airstream in an attempt to use the thrust for
speed. It made little difference but the heat was too much for my heat
shield and the foam on the belly panel in a small area distorted.
As to the construction method, I am not sure just what your expert was
asking for but, it is a wet layup, sandwich that is a common and reliable
method. It uses much more resin than the pre-preg system some kit suppliers
use for their sandwich method.
I am still in touch with guys that built their planes ahead of mine. None
of them are having the problem you described and they go back 32 years
flying. Yours may be a problem of something as simple as a bad batch of
resin. For instance, the wing and fuselage were built about the same time,
but the smaller parts were more of an inventory item. Are the areas noted
in both wing and fuselage? Are you finding it in the flaps, which is
probably the highest stressed sandwich parts and likely built at a different
time?
In any case, I disagree that the planes are life limited at 20 years. Robin

I had a composite expert look at my Glasair and the delaminating factory
pieces has turned out to be much more serious than I thought. He used
various machines and found huge areas coming undone. He recommends cutting
them out and installing new hard foam and applying lay ups over it all. This
is going to be one huge task. Lets hope that they assembled their spars
better. It is beginning to look like after twenty years or so that Glasairs
are throw away planes. Her wanted to know Stoddard Hamilton's method and I
had know idea what to tell him. What ever it was it was wrong. Chuck

Robin, I decided to remove the rear luggage compartment to see the back
side of the area of delaminating and found an old battery vent pipe hole to be
in the center of my delaminated area. During the building process in 1991
I had to move the battery forward to fix a c.g. problem and plugged that
hole with Q cell and resin. I think what happened is last winter I had the
engine out for over haul and set the tail on a horse and as the fuselage
sweated moisture ran down and gathered in that area and somehow worked it's
way down and after several freezes pushed the laminates away. Looking back I
should have applied a laminate over that filled hole. I also think that
composite expert using his tapping tools and detector mistook the elevator
control area as being delaminated. I have narrowed it down from a few square
feet to a 3 inch diameter. I tried injecting resin from the back through
drilled holes and used a 3 inch round block on a jack to push the laminates
back up. If that doesn't work I will remove the 3" delaminated area and
apply fresh laminates. I have also put my suicide sword away. I had a NASCAR
mechanic build my engine and new exhaust system and my new air speeds with
my new blended foil prop have been dazzling. At 3,000 feet 25 squared my GLS
FT was truing out at 230 mph. Witnesses on the ground report they have
never seen a plane go that fast and that it sounded like a war bird. That
NASCAR mechanic directed my exhaust into a large collector and then into a
three inch exhaust pipe. The exhaust pipe points down to where it misses the
bottom of the cowling by less than 1/4 half of an inch. And the system has a
chrome powder coating that reduces heat. I did notice some scorching and
have applied an aluminum heat shield. If that doesn't work I will use
stainless over insulating material.
Thanks,
