I am exercising the privileges of a rating endorsed on an ICAO Third Country licence, is there any possibility of endorsing it on the PART FCL licence?

Provided that you meet the requirements for this, you have the possibility to undergo the procedure for acceptance of class or type ratings endorsed on licences from an ICAO third country. The following options are currently available:

1. Annotation with restriction to ICAO Third Country registration.
2. request prior authorisation from EASA for the endorsement of the rating without restriction to registration
3. apply for both procedures
