  • Special airworthiness certificates can be issued if the aircraft does not meet the airworthiness standards, but it is deemed that it can be operated safely by partially limiting the scope of operation and flight performance. Currently, Korea is subject to experimental special certification for UAS(Unmanned Aircraft Systems) exceeding 150 kg of its own weight, but detailed guidelines need to be prepared on how to prove that they can be operated safely in a limited range. Recently, Korea Airworthiness Standard(KAS) Part 21 has been revised to reflect this, but it needs to be supplemented. In this study, through an understanding and analysis of the FAA's procedure of expeirmental special airworthiness certifications for UAS, we would like to suggest what we should consider when developing relevant guidelines in our country.

  • For operating military aircraft, military certificate of airworthiness (MCA) must be obtained from military authority. Among procedures of general airworthiness certification, there is a military type certification process that aircraft design complies with military airworthiness certification criteria. The Surion is the first military rotorcraft which has obtained military type certificate, production validation and airworthiness certificate in Korea, and the Surion derivatives for special mission are being operated for government services. Based on Aviation Safety Act, in order to operate the Surion derivatives (military aircraft) for special purpose (such as emergency patient transportation and firefighting), the issuance of special airworthiness certificates was needed from civil airworthiness authority, and the restricted category type certification (RTC) is one of design approvals for special airworthiness certification to be streamlined. This study discussed the procedures for acquiring RTC for special purpose operation of the Surion derivatives classified as military derived aircraft, and suggested procedural ideas to improve Korean RTC system.

  • In the present study, which is currently operating domestically and internationally, from the Technical Standards for Flight Safety of Light Sport Aircraft and certification system through a comparative analysis of the LSA Category Airworthiness Certifications documents. In particular, an aircraft type analysis of FAA certified S-LSA that the speed greater than 120 knots LSA manufactured without United States of America. Through the analysis, we presented a revised plan to activation of the domestic aviation leisure sports and the development of the Light Sport Aircraft industry in reality.

A Study on the Certification System for eVTOL Aircraft (전기추진 수직이착륙 항공기 인증제도에 대한 고찰)

  • As the feasibility of urban air mobility (UAM) service using electric vertical take-off and landing (eVTOL) aircraft increases due to aircraft electrification, distributed propulsion, and artificial intelligence technologies, the U.S. and European aeronautical societies have been improving their certification system and regulations for the type certification of eVTOL. The improved certification system is expected to be ready in the near future, after the European Union Aviation Safety Agency (EASA) proposed the VTOL Special Condition, SC-VTOL in 2019. However, the current domestic certification system is still insufficient to properly respond to eVTOL. This study investigated the development trends of foreign eVTOL and certification systems, identified considerations to improve the domestic certification system, and proposed the measures for type certificates and type certificates validation of eVTOL based on the comparison between SC-VTOL and Korea airworthiness standards (KAS).
