Purpose of This Order.

This order prescribes how the Federal Aviation Administration (FAA) issues aircraft type certificates (TC), supplemental type certificates (STC), their respective amendments, and other design approvals, in restricted category and details the responsibilities and procedures for type certification of restricted category aircraft pursuant to Title 14 of the Code of Federal Regulations (14 CFR) 21.25. The directives contained in this order are not intended to duplicate those in other FAA orders; rather, this order is intended to supplement the procedures in Order 8110.4, Type Certification, and other orders such as those covering the changed product rule (CPR), certification project notification (CPN), issue papers, instructions for continued airworthiness (ICA), and compliance statements. This order contains requirements specific to restricted category type certification. When differences in procedures or requirements for restricted category type certification arise between this order and another FAA order, follow this order. Contact the AIR Design Certification Section (AIR-111) if you have any questions.
