I have done some, and have got onto the EAA register for this. They sent me some more paperwork only yesterday. It says
"Requirements for Young Eageles Pilots include:
*signed registration form from parent/guardian
* appropriate rating & endorsement for a/c to be used
* biennial & 90 day reequirements completed
* aircraft must be maintained according to the FAR's
* Pilot must be an EAA member
* Aircraft liability insurance
* Flight under VFR only
* no hot loading/unloading
* no aerobatics "
I guess the PFA requirements mirror these pretty closely.
Good luck, it is very rewarding.
