Can I validate the License obtained outside the EASA environment?

There is no process for validating aircraft maintenance licenses obtained outside the EASA environment. EASA only recognises for the issue of LMA Part 66, the training obtained and passed as set out in Annex III (Part-66) to Regulation (EU) 1321/2014. 
 
You can find information about the application for licenses in Spain in the “User Guide” at the following link.
