AA21 FAA TSO Transferred to AEM

AEM is pleased to advise that after 20 months of collaboration between AEM, Cobham Aerospace Communications (CAC), Transport Canada and the *FAA, we have now completed the transfer of the AA21-400 product family and related TSO from CAC to AEM. The collaboration included the development of a precedent-setting process to allow the transfer of an FAA TSO to a ‘foreign’ country.
