EK380,
Just to point out if you are flying the aircraft type on your ICAO license and you have that same rating on the EASA you are exempt from any additional training to renew even if it is over 3 years. One EASA ATO tried that trick with me last year until I provided the EASA derogation and letter from the UK CAA confirming this. Soon as they received it they agreed its just a simple LPC when you want to use the EASA rating again. How could it be any different when you consider to transfer the type to the EASA license in the first place requires only one LPC and a visit to the CAA with the appropriate fee.
