Types of Organizational Designation Authorizations

The following are the different types of Organizational Designation Authorizations for which qualified organizations may apply.

TC ODA — Holders of a TC ODA may manage and make findings for type certification programs. In addition to the engineering and manufacturing approvals that are part of the certification program, a TC ODA holder may issue airworthiness certificates, but may not issue an original type certificate (TC) or amended TC. A TC ODA is available to organizations holding a TC issued by the FAA.
