Bose-X,
I never had to ask for permission to perform a check from a different NAA. our standard team had a look at it and specify what I could or could not do, for instance sign or not the license and that was it.
Think about company like CAE, Flightsafety which employs UK examiner and do training and checking on all the european countries pilots. If they have to sent all their SFE/TRE to each different EASA country to receive a briefing, do you imagine the price of it or if they have to pay a fee to get it authorize, do you imagine the cost.
Looks like EASA did one more big **** up again, not listening or asking the people doing the job!
So I heard that CAE, FSI, .... are not going to do it. and if EASA disagree they will stop doing any checks until it is sorted out. we will see how that works !
