Design Approval Organization
DAOSection 05: Delegation & Roles
Definition
A TCCA-authorized organization under the Canadian Aviation Regulations (CAR Part V, Division 2) that holds delegation to perform design approval functions on behalf of the Minister of Transport. The DAO operates under a Design Approval Organization Procedures Manual and employs authorized persons who make findings of compliance with applicable airworthiness standards. The DAO framework enables Canadian design organizations to approve modifications, supplemental type certificates, and other design changes within their scope of authorization.
Where This Shows Up
The TCCA DAO is functionally analogous to the FAA ODA (for design functions) and the EASA DOA. Canada's regulatory framework under the Canadian Aviation Regulations mirrors many ICAO principles while maintaining unique administrative procedures. DAOs are particularly important for Canadian STCs and modifications.
