What certificate is issued when an aircraft conforms to its design?

The certificate issued when an aircraft conforms to its design is known as a Type Certificate. This document is crucial in the aviation industry because it signifies that a particular aircraft model, or type, has been evaluated and meets the applicable safety and regulatory requirements set by aviation authorities. The Type Certificate provides assurance that the aircraft has been tested for performance, design, and safety standards, indicating that it is airworthy and compliant with regulatory specifications.

The importance of the Type Certificate cannot be overstated, as it forms the basis for the production and operation of that specific aircraft type. Once a Type Certificate is granted, manufacturers can produce the aircraft in conformity with the approved design specifications.

In contrast, while the Certificate of Airworthiness (C of A) is vital for ensuring that an individual aircraft is fit for flying after it has been built or modified, it does not address the conformity of design itself. The Certificate of Conformity may refer to whether manufactured components conform to their specifications, but it does not encompass the full evaluation of the aircraft type as a whole. Similarly, a Supplemental Type Certificate (STC) is specific to modifications made to an existing aircraft design, which means it is not applicable for confirming the original design's conformity.

Thus, the Type Certificate
