Hey there. I'm looking for some insight/suggestions on renewing my Instructor certificates. I hold a CFI/II/MEI (airplane land) certificate & an ATP ASEL&AMEL certificate. My instructor cert. comes up on its 2 yr anniversary in a couple months. I have always wanted to be able to enjoy the seaplane world & therefore was thinking of how I could tie it in w/ my CFI Renewal. Could someone tell me what all I would need to do to get a seaplane rating added to my cert.? Would I first need to get the seaplane rating added to my pilot cert. (?). If so, then any reason that couldn't simply be an add on to my ATPL(i.e.-no minimum seaplane time, etc.)? If I need to do an add on to my pilot cert. prior to my instructor cert., then would doing so in a multi seaplane give me both single engine & multiengine sea privilages??? And, what's the possibility of the seaplane pilot&instructor checkride all together? Pros, Cons, past experiences, ... all would be greatly appreciated. Thanks, AV8N4Fun
