Domestic Certification

The process for domestic certification is controlled by FAA Order 8110.4.

In order to ensure that significant issues as defined in Order 8110.4 are identified upfront for all transport airplane certification projects, the Transport Airplane Directorate (TAD) maintains a list of known issues that require TAD involvement � the Transport Airplane Issues List. The Transport Airplane Issues List is intended to contain all known significant issues; however, new significant issues are identified periodically. For example, the first time a new design feature is certified on an airplane, the design feature would not be on the Transport Airplane Issues List (PDF), but would still be significant and require TAD involvement.

International Validation: Non-EASA

The process for international validation is controlled by Order 8110.52, Type Validation and Post-Type Validation Procedures. To ensure consistent treatment of issues for both domestic certification and foreign validation programs, the Transport Airplane Issues List, described above, is also used as a tool to identify issues in foreign validation programs.

International Validation: EASA/JAA

The FAA and Joint Aviation Authorities (JAA) established type validation principles in 1997 to guide the airworthiness certification of each others products.  These principles were subsequently incorporated into the Bilateral Agreements established between the US and a number of European countries. They have since been enhanced and reconfirmed with the European Aviation Safety Agency (EASA), as documented in Order 8110.52.

These principles obligate each authority to publish and periodically update Standards Differences.

Each authority is also obligated to publish and periodically update a list of Generic Validation Items (Generic VI). Generic VI consist of certification subjects that have been identified by each authority for review in all products of a certain class.

The FAA Generic Validation Items for transport category airplanes are of two general types: commonly occurring project Validation Items, and published policy memorandums. Current policy memorandums are obtained from the Regulatory and Guidance Library (RGL). The TAD maintains a list of known issues other than policy memorandums that require TAD involvement � the Transport Airplane Issues List (PDF). To ensure consistent treatment of issues for both domestic certification and foreign validation programs, the Transport Airplane Issues List and the Generic VI List have been standardized such that the Transport Airplane Issues List, together with the current part 25 policy memorandums on RGL, constitutes the Generic VI List for the purposes of transport airplane FAA/EASA/JAA validation programs.

The FAA will review the list of Generic VI subjects during its familiarization review of a product to identify those that are applicable to the product. Those that are determined to be applicable will be further developed by the FAA and presented to the applicant and exporting authority as project-specific issues. These Generic VI subjects are presented in the Transport Airplane Issues List in summary form to provide interested persons with an overview of those issues typically considered by the FAA in its validation of imported transport category airplane designs. Requests for further information regarding any of these identified subjects should be directed to the FAA Transport Standards Staff.
