The process for domestic certification is controlled by FAA Order 8110.4C.
In order to ensure that significant issues as defined in Order 8110.4 are identified upfront for all rotorcraft certification projects, the Rotorcraft Directorate (RD) maintains a list of known issues that require RD involvement, the Rotorcraft Significant Project List. The Rotorcraft Significant Project 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 a rotorcraft, the design feature would not be on the Rotorcraft Significant Project List (PDF), but would still be significant and require RD involvement. The RD Significant Project List will be reviewed quarterly and updated as needed.
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.
Validation Differences: TCCA
The following tables provide a list of areas where the FAA's 14 CFR Part 27 and Part 29 regulations differ from the TCCA standards for normal and transport category rotorcraft.
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.
