Aircraft parts are considered as a significant element for the continued airworthiness of the certified aircraft well as a partial component consisting of the new aircraft design. US FAA established the certification system of Parts Manufacturer Approval in 1965, which is contributing to the continued airworthiness of the aircraft in operation and to the expansion of worldwide market of aircraft parts. In this paper, we compared the differences of the certification systems between FAA Parts Manufacturer Approval and EASA European Part Approval, and proposed the rulemaking items to improve Korean Parts Manufacturer Certification System and to contribute to growth of aircraft parts industry.

Certification by Civil Aviation Law is necessary for aircraft parts and appliances as well as aircraft, engines, and propellers to ensure safety and reliability in operation. Advanced countries in aerospace industry as like U.S.A require Parts Manufacturer Approval for aircraft parts and Technical Standard Order Authorization for designated appliances. However, there are no legal requirements for certification of aircraft parts and appliances in Korea until now. This study presents the draft to revise Civil Aviation Law, which is applicable to set up domestic certification system and maintain it equivalent to U.S. Federal Aviation Regulation.

From design to serial production, aircraft should go thorough complicated certification procedure from airworthiness authority such as Type Certificate, Production Certificate and Certificate of Airworthiness. On the other hand, aircraft components are mandated to receive Technical Standard Order Approval and Production Manufacture Approval before commercial use. As domestic aircraft and LRUs are currently under development, Bilateral Aviation Safety Agreement is promoted for the purpose of increasing aviation safety as well as foreign export. This paper describes the basic aircraft certification procedure and compares the difference in the certification system of US and Korea. Thorough this, it is attempted to suggest a requirements for establishing international certification system.

This study derived a reverse engineering procedure for verifying the design identity of original parts and developed parts for PMA(Parts Manufacturer Approval) and STC(Supplemental Type Certificate) of metal brake pads for transport aircraft, which are critical parts among aircraft parts and equipment. In Korea, the regulations for reverse engineering procedures are regulated by the Parts Manufacturer Approval Guidelines, and in the United States, AC No. 21. 303-4. In the reverse engineering for the brake pad, the detailed procedures for each component were determined by selecting verification test items to confirm identity based on sample quantity, dimensional tolerance, mechanical property measurement, material, weight and volume characteristics for each component. In addition, as a result of analyzing the regulation of Korea and United States, in the case of Korea, it is necessary to establish technical standards for braking systems for transport aircraft and regulations related to flight tests.

Until now, The Market of aviation parts had led by OEM(Original Equipment Manufacturer) parts because of aviation industry's nature required higher reliability and safety. But recently, The interest about PMA parts in aviation market is increasing continuously with various environmental changes, such as economic stagnation, oil price rise, development of the manufacture technique and newly rising market of Asia-Pacific region. So, this paper introduces the trend and the requirements of FAA PMA / EASA EPA in order to enhance understanding for certification for aviation parts.

Until now, The Market of aviation parts had led by OEM(Original Equipment Manufacturer) parts because of aviation industry's nature required higher reliability and safety. But recently, The interest about PMA parts in aviation market is increasing continuously with various environmental changes, such as economic stagnation, oil price rise, development of the manufacture technique and newly rising market of Asia-Pacific region. Actually, after 2006, FAA PMA approval parts are increasing at a rate of around 40,000 parts per year and 2.5% of PMA parts penetration, in 2007, in Asia-Pacific market is forecast to enlarge up to 8% in 2017. So, this paper introduces the process requirements of FAA PMA / EASA EPA and the status of PMA market in order to enhance understanding for certification for aviation parts and to review a new PMA market.

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.
