I'm thinking about to bring N-reg aircraft for renting it in Europe. It would be operated only in one European country.
FAR 61.3 (a) (1) says: "when operated within a foreign country, a current pilot license issued by the country in which the aircraft is operated may be used".
I've seen that there are few companies renting N-reg for flying in Europe like this one
N5274A - Beautiful Cessna 172 SP for rent in Cologne / Germany - Welcome!
What are the regulations for doing this kind of renting in Europe?
Particulary I'm interested in payment details.
