  • An aircraft, its engine and propeller are certified in processes of design, production, and operation respectively. Type Certificate is issued if the aviation authority finds that the design of aircraft, engine, or propeller complies with applicable airworthiness standards and environmental standards. The ICAO (International Civil Aviation Organization) prescribes the international standards and recommended practices of type certification for the contracting states. The FAA (Federal Aviation Administration) and the EASA (European Aviation Safety Agency) established their regulations and procedures applicable to type certification. In this paper, we compared the differences among the ICAO, the FAA, and the EASA regulations, and on this comparison, we proposed the rulemaking items to improve type certification regulations in Korea.

  • 항공기의 성능 개선이나 관련 법규의 요건 만족을 위해 항공기 시스템 개조는 필요하다. 이러한 개조를 위해 기술력이나 항공기의 감항성을 위한 설계 검증, 형식 증명에 대한 부가형식증명(STC)의 인증 절차는 적절한 표준이 요구된다. 본 연구는 국내 항공기 개조 현황과 수요를 분석하고 현재의 부가형식증명 절차를 검토하여 그 문제점을 진단한다. 또한 늘어난 항공기의 수명에 대하여 개조기술 및 인증 능력 향상방안을 연구한 결과 개조 조직의 인가와 분야별 전문 엔지니어 자격 임명 그리고 교육 체계 개선이 요구되었고 국내 부가형식증명 절차의 개선을 도출하였다.

  • 항공기의 설계 안전성을 보장하기 위하여 형식증명을 받아야 한다. 형식증명을 받은 항공기의 설계가 중대하게 변경되는 경우, 형식증명을 새로 받거나 개정형식증명 또는 부가형식증명을 신청하여야 한다. 국제민간항공기구, 미국 및 유럽의 인증 규정에서 부가형식증명 대상이 되는 설계변경에 대하여 매우 추상적으로 정의하고 있으므로, 본 논문에서는 설계변경에 관한 세계 각국의 인증절차와 인증사례를 분석하여 부가형식증명 대상이 되는 "광범위하지 않은 중급 설계변경"을 판단하는 기준을 제시하였다.

  • The purpose of this study is to explore ways of improving the motor vehicles safety certification system in preparation for the deployment of Lv.4 or higher autonomous vehicles. In order to effectively achieve the objectives of this study, theoretical and empirical research methodologies were employed, including literature review of prior research, government-published data, etc.; comparative research on legislative cases of other countries regarding motor vehicles safety certification; historical and legal research on domestic systems; legal analysis to explore approaches for improvement, etc. Some argue that the type approval system is needed in preparation for deploying autonomous vehicles, but there are several limitations in moving to the type approval system from the self-certification system currently adopted in Korea. First, there is a possibility that the system may be in conflict with the Korea-U.S. MOU regarding Foreign Motor Vehicles (1988) and the Korea-U.S. FTA (2011); second, there is a risk of undermining the cause of the self-certification system, which is the autonomy of manufacturers; third, the boundary between autonomous vehicles and non-autonomous vehicles is unclear; and fourth, the type approval system may hinder technological competitiveness. On the other hand, considering that the Korea-U.S. FTA and the UNECE IWVTA recognize exceptions to deal with road safety and risks to human health or the environment, and have a pre-certification system for some auto parts such as pressure-resistant containers, it can be said that there is room to introduce the type approval system for supplementation purposes. To improve the motor vehicles safety certification system while ensuring the safety of autonomous vehicles of Lv.4 or higher, the targets of type approval should be defined and the criteria, procedures, etc. for type approval should be established. At the same time, the consistency between motor vehicle-related laws and harmonization with international standards need to be considered.

  • 항공기 추진시스템 전동화, 분산추진기술, 자율지능기술의 발달로 전기추진 수직이착륙 항공기(eVTOL: Electric Vertical Take-off and Landing)를 활용한 도심항공교통서비스 구현 가능성이 높아짐에 따라 미국, 유럽 등 항공선진국들에서 전기추진 수직이착륙 항공기에 대한 인증제도 연구가 활발히 진행되고 있다. 2019년 유럽항공안전청이 수직이착륙 항공기를 위한 새로운 기술기준 SC-VTOL을 고시하는 등 근시일 내 인증제도 마련이 예상되나 국내 인증제도는 eVTOL 항공기의 개발과 시장 운용에 대비가 미비하다. 본 연구에서는 해외 eVTOL 개발과 인증제도 마련 동향을 조사하고, 미국/유럽의 제도개선 방향을 분석하여 국내에 관련 인증제도 마련을 위한 고려사항을 분석하였다. 이 후 SC-VTOL과 현행 국내 항공기기술기준을 비교분석하고 국내 eVTOL 항공기 형식증명/형식증명승인을 위한 방안을 제시하였다.

  • 유럽의 경우 항공기 엔진 개발 시 유럽항공안전청(EASA)에서 제시한 형식증명 기준을 통과해야 한다. 그 중에서 엔진의 운전한계조건에서의 엔진 구조 안정성을 입증하기 위하여 150시간 내구시험을 수행해야 한다. 150시간 내구 시험의 만족기준은 유럽항공안전청의 형식증명 기준인 JAR-E에 명시되어 있다. 현재 국외 엔진 원제작사와 협업을 통하여 Arriel 2L2 엔진을 개발 중에 있으며, 형식 증명을 위하여 150시간 내구 시험을 수행하였다. 본 연구에서는 개발대상 엔진인 Arriel 2L2 엔진의 설계 및 운용 특성을 고려한 150시간 내구시험 수행 및 절차를 정립하였다.

  • Purpose - The distribution of agricultural products is changing due to recent shifts in environmental free trade. Specifically, the competitiveness of domestic agricultural products has weakened as a result of the Korea-China Financial Trade Agreement. Agricultural producers are faced with increasing difficulties and organized production centers are growing in importance daily. To overcome this crisis, agricultural producer organizations are vying for environment-friendly agricultural certifications, Good Agriculture Practices (GAP) and Hazard Analysis and Critical Control Point (HACCP). In particular, as consumer demand for higher safety grows, farmers are increasing their certification rates. Therefore, this certification system is expected to help strengthen the competitiveness of agricultural producer organizations. Research design/data/methodology - Organized production centers are classified by certification. A survey was conducted with 91 organizations using factor analysis and logistic regression analysis for the examination. The factor analysis results are as follows. Raw material procurement, education·specialization, marketing, joint business, organizing ability, business management, effectiveness, certification, and larger organizations were classified as the nine types of factors. These factors affect the organized production centers and are used in the logistic regression analysis. The purpose of such research and analysis is to suggest a direction for future production center policies. Results - The basic statistical results are as follows: analysis of the producer organizations of 91 sites, average number of members per site of 1,624, and average sales of 25,961 million won. Additionally, the average income per farmer is 175 million won, and the pooling system rate is 53.5%. The factor analysis results are as follows. Factor 1 consists of contract cultivation, ongoing shipment, selection subdivision, traceability, and major retailer management. Factor 2 consists of manual cultivation, specialty selection, education program, and R&D. Factor 3 consists of advertising, various dealers, various sales strategies, and a unified sales counter. Factor 4 consists of agricultural materials co-purchase, policy support, co-shipment, and incentives. Factor 5 consists of the co-selection and pooling system. Factor 6 consists of co-branding and operating by the organization's article. Factor 7 consists of the buy-sell ratio and rate of operation of the agriculture promotion center. Factor 8 consists of bargaining power in volume and participation rate of farmer certification. Factor 9 consists of increasing new subscribers. The logistic regression analysis results are as follows. Considering the results by type of certification, the environment-friendly agricultural certification type and the GAP certification type have a (+) influence. GAP and HACCP certification types affecting the education·specialization factor have a (+) influence. Considering the results for each type of certification, the environment-friendly agricultural certification types on the effectiveness factor have (-) influence; the HACCP certification types on the organizing ability and effectiveness factor have a (-) influence. Conclusions - Agricultural producer organizations should develop plans as follows: The organizations need to secure education for agricultural production; increase the pooling system ratio for sustainable organizational development; and, finally, expand the number of agricultural producer organizations.
