Since Korea has invested only on developing an aircraft, it is true that Korea has neglected detailed standards and procedures about certification activities including essential safety procedures. Most developed countries have implemented mandatory airworthiness system by legislating it for operational safety of aircraft based on ICAO Annex 8, and the U.S. Department of Defense and the FAA's Airworthiness system have been adapted it to the realities of their circumstance. Therefore, Airworthiness system that can guarantee the safety of the aircraft at international level is necessary to enhance flight safety and to create export opportunities of an aircraft as a country which can develop an aircraft by itself To achieve this, a study on the improvement of aircraft airworthiness was carried out by analyzing the problem of domestic airworthiness system and by reflecting international best practices on the establishment of a system for improved Airworthiness.

KC-100(KAI Civil Aircraft, Small Series) aircraft is 4 seats general aviation aircraft with single piston engine which is developing under FAA part 23 category by Korea Aerospace Industries(KAI) and will be a shadow program for civil aircraft safety infrastructure improvement. This aircraft will be the first civil aircraft developed in Korea meeting the Korean regulatory KAS Part 23 requirements. Type certification for KC-100 aircraft was applied at the second half of this year. The type certificate is expected to be issued after 3 years of design, prototype manufacturing, ground and flight tests. In this paper the system engineering process for civil aircraft was first reviewed. Next, the differences and similarities in the system development between military and civil aircraft were systematically examined using experiences for KAI military aircraft development program.

Korean civil airworthiness requirements of powerplant system are regulated on KAS Part 23 and Part 33. These are equivalent to FAR Part 23, Part 33 of FAA and CS-23, CS-E of EASA. FAA and EASA rewrites entire airworthiness requirements for the small airplane. It changed current 'prescriptive regulation' into 'performance-based regulation' which makes the object of safety performance. Powerplant requirements are also changed extensively by these concept revolution. In accordance with reorganization, we studied new powerplant system requirements of FAR Part 23 and proposed ideal direction to rewrite of Korean Airworthiness Standard rewrite.

Most of the aerospace industries establish the SAE AS9100 Quality Management System, and acquire commercial certification by the 3rd party. Nevertheless, they repeatably have to cope with similar quality system evaluation by the airworthiness authority for the production certificate, parts manufacturer approval, and technical standard order authorization in accordance with the applicable regulations. The current quality system evaluation criteria of the airworthiness authority could be recommended for reforms in order to reduce duplication and correspond to the industrial development and environmental changes. In this paper, we propose measures to reform the authority's evaluation criteria through comparative analysis among the IAQG SAE AS9100, the FAA quality system codes, and the MOLIT ACSEP requirements.

This study described about the procedure and method to type certification of KAS 23 civil aircraft that is developed in domestic. It is important to obtain type certification within defined period based on the proposed process and method to prove compliance through certification basis according to certification plan. This process referred to FAA Order 8110.4 C, "Type Certification" and domestic regulation and showed example of compliance check list(CCL) defining means of compliance(MOC). Also, proposed method to prove compliance according to means of compliance and classified item of test & evaluation.

New aircraft category such as Light Sport Aircraft is introduced to prevent Ultralight Vehicle accidents and to promote aviation sports. Therefore, a new rule for airworthiness standard, certification, operation and maintenance of light sport aircraft is being created. The present study deals with LSA concept, development trend of LSA, airworthiness standards and certification policy. In particular, an aircraft type analysis of FAA certified LSA is conducted to establish performance requirements of Light Sport Aircraft designs.

항공전자부품은 항공기의 핵심기능 분야를 구성하는 부품으로서 개발 및 제작 단계에서 안전성 및 신뢰성 평가를 수행하여야 하며 개발한 항공전자부품을 항공기에 창착하기 위해서는 감항기준에 의거한 적합성을 검증 받아야 한다. 미국 연방항공청에서 고시하고 있는 기술표준품(TAO) 중 항공전자부품은 약 65%를 차지하고 있으며 TSO로 지정되지 않은 PMA 부품 등을 고려하며 부품의 종류 및 량은 상당수에 이르고 있다. 최근의 항공전자부품은 디지털화의 가속화로 비행안전기능이 보강되고 조종사의 업무강도를 줄이는 방향으로 발전되어 가고 있다. 그리고 이러한 분야에는 소프트웨어가 채용되어 소프트웨어의 인증이라는 인증절차가 개발되고 있다. 이 글은 국산 항공전자부품의 개발에 앞서 항공전자부품의 인증 내역을 제시함으로서 국내 독자적인 인증 수행은 물론 설계 참여자들이 인증에 대한 인식이 될 수 있도록 하였고 내용적으로는 미연방항공청(FAA)과 유럽공동감항기구(JAA)의 절차를 중심으로 작성하였다.

In this paper, we analyzed the requirements for the application of UAM, a new concept to solve the traffic congestion in large cities. First, the current domestic and foreign status of research and development related to UAM was investigated and the pros and cons and the time required for each mission radius were analyzed for various configurations of aircraft being commercialized. In addition, in order to analyze the market acceptance of the UAM, the individual's consciousness and reliability requirements were identified and safety requirements were analyzed through accident rate data for each aircraft type. Because it operates in a densely populated urban area, requirement analyses on noise and exhaust, which are environmental factors that can affect the community were performed, and requirements related to aircraft performance, certification standards, and airworthiness standards of FAA and EASA were also analyzed.

Safety and Reliability assessments of Avionics Parts must be conducted essentially in the step of disign and manufacture as it constitutes a major field of aircraft critical operation. Recently Avionics parts fabrication techniques are continuously developing by applying digital techniques. Airborne computer is being adopted on an aircraft for flight is being adopted on an aircraft for flight safety augmentation and simplification of controls including reduction of human error. Therefore inspection and evaluation procedures should be developed in order to accomodate such trends. The number of avionics parts is approximitely 72% of total TSO parts, so it is expected high added-values through manufactures of TSO parts in aircraft industries. Particuarly avionics parts must be manufacturered with our own technology to be used in Mid-class aircraft which will be developed soon. Along with this, preparation of Certification Procedures is essential for Avionics Parts.
