Don't know how other ones are passing the test, but the way composites are
typically given lightning protection is to embed a metal mesh in the layup. I
didn't think this was critical for fiberglass, only graphite composites.
Graphic will conduct, but it also has higher resistance than metal. So a bolt
of lightning will cause extremely rapid heating, in other words an explosion.
By embedding a metal mesh, you are providing a lower impedance path for the
electrons to flow. I wonder if you could argue that there is already a bunch
of fiberglass (wingtips, nose bowl) on the Grummans to get out of the testing.

And maybe more importantly did American General have to embed any metal in
their cowling?

Just toured the Columbia factory Wednesday and saw the wire mesh installed on the
outer surface of the"fiberglass" wing. The wing has very little carbon fiber
in it, only at a few hard spots is carbon used n the Columbia.
I don't think my AG5B has any metal mesh or other lightning strike considerations
in the cowl. It does consist of carbon fiber and fiberglass.
I just don't think the FAA should be able to hold Gary's cowl to regulations not
in force at the time the TCDS was approved on the grummans....I think this was
true of the AG5B
