Certification Branches (formerly Aircraft Certification Offices/ACOs)
As a result of 2023 AIR Reorganization, Aircraft Certification Offices (ACOs) are now Certification Branches
Certification Branches assist with:
- Design approval and certificate management
- Support to Certificate Management Sections for US production approvals.
- Type certification & continued operational safety questions
- Investigating and reporting aircraft accidents, incidents, and service difficulties
- Designated Engineering Representatives (DER) oversight
