FAA licence validity
 

Could anyone please shed light on the requirement of keeping either a NZ, Australian, Canadian and US FAA licence current. My concern is I do not want any of them to expire and have to resit the exams/etc. So with that in mind are they all life time licences? That is, complete a medical and PPC/Instrument check and it is effectively renewed. How many years after no contact with the respective authorities do they expire? If ever? I am not operating on any of these presently so anyone with information on all/any would be helpful. Yes I know I could check the websites, contact the authorities, etc concerned but anyone that has information or in the same position is so much more practical than screening pages of the net or dealing with 20 phone calls to get to speak to the right person? Ok with that thankyou to anyone with a informative reply.

An FAA airman's certificate does not expire. An FAA Flight Instructor's certificate is only valid for two years, and then must be renewed prior to expiration.. .. .An FAA airman's certificate is only valid with a current FAA medical certificate, but does not expire.. .. .CFI/CFII/ATP
