What is a Certificate of Airworthiness for How do I get it

A Certificate of Airworthiness (CdA) is the document that certifies that an aircraft is capable of performing flights under certain safety requirements. This document is issued by the national authority where the aircraft is registered.

For non-EASA aircraft, the design of which is not covered by a valid type-certificate, does not have a Configuration Definition Document or is covered by a type-certificate or equivalent not accepted by AESA, the issuance of a CoA shall not apply to them.

To obtain the type of Airworthiness Certificate there is a user manual that varies depending on the characteristics of the aircraft. The manual also gives instructions on how to perform subsequent activities after obtaining the Airworthiness Certificate, such as modifications, suspensions, etc.

There is a User Manual in the Amateur Aircraft Construction section or in the various sub-sections within the Airworthiness Certificate section, except for remotely piloted aircraft (known as UAS) and experimental non-UAS aircraft, for which prior contact with the authority is required.
