I am looking at FAA IR
training only, at PPL level.

That requires it, as the current interpretation stands.


The curious thing is that training with a JAA instructor is allowable
towards the FAA IR, and would not need any such checks.


Such training counts? Where does it say that? What is the exact text of
the TSA requirements towards what the student and what the instructor
have to do and how does it relate to what is said about JAA instruction
being valid?
