Understand that bolts used in aircraft construction are not "hardware

tension to hold the wing on the Bonanza, Baron and King Air models. When
there is a crash, the bolts are rarely broken.

Well, Beech used to use bolt in tension on the King Air. But a bunch of them
had their wings fall off.

Now they use bolts in shear.
