What is an Original Design Approval Process?

An original FAA design approval is a five-phase process in which an applicant applies for design approval of an aircraft. The end result, if approved, is a Type Certificate. The steps to approval are:


Phase 1 – Design and Concept

This is the fun part! This phase is initiated when the applicant begins design concept for an aircraft that may lead to a viable certification project. Risks are evaluated, and regulatory requirements reviewed. The applicant will begin generation of a Project Specific Certification Plan (PSCP). The PSCP is a tool used to manage the certification project.


Phase 2 – Formal Application

The red tape has officially started! Design of the aircraft is completed, and applications are sent to the FAA for their initial review. The PSCP is getting more detailed and formalized.


Phase 3 – Planning

All the hard work is finally paying off! During this phase, the PSCP for the aircraft is finally complete and submitted to the FAA for final review.


Phase 4 – Implementation

Now prove it! The FAA is now actively involved in ensuring the aircraft displays the ability to function as defined in the approved PSCP. The applicant and the FAA work closely in managing and refining the agreed PSCP to ensure all the requirements are met.


Phase 5 – Post Certification

The finish line! This is when you close out activities with the FAA and they provide the Type Certificate for the remainder of the aircraft’s life cycle. Congratulations! You may now apply for an Airworthiness Certificate.
