- Type Certification ODA (TC ODA)
- Supplemental Type Certification ODA (STC ODA)
- Production Certification ODA (PC ODA)
- Parts Manufacturer Approval ODA (PMA ODA)
- Technical Standard Order Authorization Holder ODA (TSOA ODA)

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.
STC ODA — Holders of a STC ODA may develop and issue supplemental type certificates (STC)s and related airworthiness certificates. An STC ODA is intended primarily for repair stations, operators, and manufacturers, but consultant groups with the required knowledge and experience may also qualify for an STC ODA.
PC ODA — Holders of a PC ODA may issue airworthiness certificates and approvals, determine conformity, perform evaluation leading to amendment of its production limitation record, and approve minor changes to its quality control manual. To qualify for a PC ODA, an applicant must be an existing production certificate (PC) holder, or have applied for a TC and PC.
PMA ODA — Holders of a PMA ODA may issue PMA supplements based on test and computation approvals, STCs, or licensing agreements. Only existing PMA holders qualify for this ODA type.
TSOA ODA — Holders of a TSOA ODA may issue airworthiness approvals and determine conformity of articles, test articles and test set-ups in support of FAA managed TC or STC projects. Only existing technical standard order (TSO) authorization holders qualify for a TSOA ODA.
MRA ODA — Holders of an MRA ODA may approve data for major repairs and alterations, issue airworthiness certificates and approvals, and perform aging aircraft inspections and records reviews. Repair stations and operators qualify for all functions available under MRA ODA. Consultant groups are only eligible for engineering approval functions.
AKT ODA — Holders of an AKT ODA type are responsible for testing center personnel and facility management, administration and delivery of airman knowledge tests, and issuance of airman knowledge test reports (AKTR) to airman applicants. The AKT ODA managing office is the Airman Testing Standards Branch (AFS-630), located in Oklahoma City, Oklahoma. AKT ODA must be reviewed, approved, and authorized by this office
AO ODA — Holders of an AO ODA may conduct certification or portions of the certification process towards issuance of a Rotorcraft External-Load Operator Certificate. ODAs for operational certifications may be expanded in future revisions of this order to include additional air operator, airman, air carrier, or air agency certification functions. An AO ODA is intended primarily for consultant groups, but experienced certificated operators may also qualify.
