Are the certificates approved by EASA / FAA?

EASA does not approve any certificates for any company. They do approve EASA 147 training organizations to deliver training for Part 66 Engineers both basic and type. EASA does not approve regulatory training courses for "any organization". This role is left to the responsible operator or AMO to approve and accept the content.

Sofema Aviation Services certificates are accepted by EASA regulatory authorities as evidence that training has been completed.

The same applies for FAA related trainings.
