We started getting quite a few of our pups back from European operators
with the cad plated parts very corroded. Turns
out the Europeans were using some sort of new deicer stuff on their
runways and all. Unfortunately I do not know what
it was exactly, but you can do some testing on your own parts. Get some
old screw hardware from your local mechanic
and see what happens...


That pups should be pumps, as in hydraulic.

Cadmium plating is routinely stripped from the base metal using an amonium
nitrate solution, hence the corrosion.
