1948 seaplane exfoliation failure

One of only two exfoliation corrosion cases Tom has personally seen. Crashed near Tom's Miami apartment.

Intergranular attack — we talked about that, sensitized steels, weld decay, sensitized things. There are other things like exfoliation, where you actually grow between the pancake layers. This occurs in aluminum alloys, but we know how to control it with the proper heat treatments. I've only seen two cases of exfoliation corrosion in my life. One of them was a 1948 seaplane that crashed in Miami harbor about four or five years ago — it was in the news a lot.
