I would like to merely offer up a first topic for discussion.
Boeing and the FAA have conducted fuse pin inspections on
the 747 fleet.  A few of these inspections found cracked
pins, and quite a few found a large amount of corrosion.

Inspections have been expanded to include the engine mount
pylons.  What Im looking for is some specs on the shear yeilding of these
pins and and the stuctural integrity of the pylons.

Thanks a bunch,
