ABSTRACT
According to the International Civil Aviation Organization (ICAO), UAS must operate in accordance with ICAO Standards that exist for manned aircraft as well as any special and specific standards that address the operational, legal and safety differences between manned and unmanned aircraft operations (ICAO, 2011).When the operation of the aircraft meets the requirements it is said that it is airworthy. Airworthy means that an aircraft meets its type design and is in a condition for safe operation (FAA, 1958). This definition is taken from public law 103-272, previously the federal aviation act of 1958, and is also found on the face of each aircraft’s standard airworthiness certificate. The Article 33 of Chicago Convention states that Certificates of Airworthiness must be based on compliance with at least the minimum international (airworthiness) Standards established by Annex 8, referring the following requirements (ICAO, 2011):
a) that an aircraft be produced in a controlled manner that ensures conformity to its approved type design;
b) that a Certificate of Airworthiness be issued by the State of Registry based on satisfactory evidence;
c) that the aircraft comply with the design aspects of the appropriate airworthiness requirements;
d) that the State of Design, State of Registry and the type certificate holder collaborate in maintaining the continuing airworthiness of the aircraft.
