Yes gear UP for water and DOWN for runway, but very few give
instruction in Amphibs.

BTW, most of the accidents listed above don't result in FAA
notification. They aren't that serious and are actually INCIDENTS. They
just taxi back to the base (or sometimes even fly) , or fly the parts
in and repair it. Never seems to get reported. It's because they aren't
seriouis. But even simple screw ups can be several thousand dollars.
And like I said, it almost never haoppens with the instructor .This is
why they don't allow solos.
