The process for domestic certification is controlled by FAA Order 8110.4C.International Validation: Non-EASA
The process for approving rotorcraft in a Non-EASA country are governed by the Bilateral Agreements that are in place with that country. Depending on the country the agreement will either be a Bilateral Airworthiness Agreement (BAA) or a Bilateral Aviation Safety Agreement (BASA). If the country has a BASA with the United States it will also have Implementation Procedures for Airworthiness (IPA) that will have specific procedures that will be followed.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 are the guidance used to Validate a rotorcraft with EASA. The process for international validation for the FAA is controlled by FAA Order 8110.52, "Type Validation and Post-Type Validation Procedures."
Each authority is also obligated to publish and periodically update a list of Standards Differences and Generic Validation Items (Generic VI). Generic VI consist of certification subjects that have been identified by each authority.
- Normal Category Rotorcraft Type Validation Items (PDF) , 14 CFR part 27
- Transport Category Rotorcraft Type Validation Items (PDF) , 14 CFR part 29
- Standards Differences
14 CFR part 27 and part 29 are harmonized with European Aviation Safety Agency (EASA) Certification Specifications (CS), CS 27 and CS 29, respectively. There are no substantive standards differences.
