The shear on the bolts is minimal given the number that are picked up. The
high loads are compressive directly on the beam when you
pull a lot of G's
or during a hard landing.

Paul, I considered the shear to be a small problem at worst. The gasket however is directly affected by compressive loads or hard landings. I thought that if a gasket was used it could be compressed or shredded causing the bolts to be loose. They couldn't fall out since they would be safety wired of course.

1/2 inch wide.. 12 inches long.. six square inches... 6 g 300 pound 1800 pounds
300 psi.. well could be. I have no idea what a cured thin layer of silicone 
will take compression wise. A six G landing does not occur very often.
I guess it is easy to make a 1/2 by two inch rectangular test sample 
and apply 300 pounds.
