Why would you need convert an FAA PPL to a JAA PPL?
(Unless you want add ratings, or want to go on to obtain a JAA CPL.)
Having to passing a couple of exams and a skill test isn't too onerous. Air Law makes good sense because of different rules, and most schools/clubs would require the equivalent of a skills test before letting you SFH, but the >100 hours requirement is bizarre.
Someone who's never flown in their life can get a JAA PPL in 40 hrs (or whatever the minimum requirement is now) but a qualified pilot who already holds an FAA PPL has to have more than 100 hours total before he/she is eligible to convert it to a JAA licence.
No big deal building up to 100 hrs but, in principle, it seems outrageous.
