This one comes up often. Does anybody have a reference as to why an instructor doing an FAA BFR in a G-reg needs to have a JAA Instructor Rating?
I don't think they do, though they probably couldn't charge for the air element. In fact a bog standard JAA CPL who just happens to have a FAA CFI rating could probably even charge.
My friend did my BFR in my G reg, despite not holding JAA FI. Of course I didn't pay him, except in beer afterwards for the lift to the airfield
