The aircraft maintenance demands a lot of aviation mechanics in urgent according to the high season and low season in seasonal demand adjusted, unplanned maintenance work such as AD (airworthiness directives) and troubleshooting of aircraft system fault. The advent of Super-Large Aircraft such as A380 with aircraft materials, power plant and avionics systems which were not in previous models must be expected to increase the complexity of the aircraft maintenance system. This study is intended to propose the development plan for formation of positive flexibility culture in aircraft maintenance organization through the review of previous research on flexibility culture of organization and through empirical research for bureaucratic and poor factors by the evaluation of flexibility culture level of domestic aircraft maintenance organization.

Aviation Maintenance Technician(AMT)'s error is not directly link to deficiency which is differ to flight crew's error and it potentially maintains. Due to it usually occur as undesired aircraft state, hazards, like unreported maintenance error or near miss fortunately undetected and are not develop to accident. This could be a crucial influence of an accident occurrence. To remove these hazards, just safety culture should be support that anyone can report about safety problems and person who reported safety problems and hazards like near miss, should not get disadvantages. Also if it is satisfied, they must exempt for punishment and guaranteed for security. Hence, on this study, aviation maintenance site's just culture need to be researched and analysed about improvement for aviation maintenance field's positive just culture.

As the domestic aviation industry grows, the aviation maintenance field is also growing rapidly. This change calls for more aircraft maintenance technicians, and interest in safety accidents is also increasing. Individual safety climate indicates the importance of safety in the organization. We expect that three individual factors (training effectiveness, procedure effectiveness, and work pressure) relate to safety behavior in the workplace via individual safety climate. The purpose of this research is investigating the relationship between individual factors and aircraft maintenance technician's safety behavior. Previous studies related to individual factors were examined for literature review. Based on the previous studies, research model was constructed. Hypothesis was verified by effected data from 305 samples were employed for final survey. The results show that individual factors were meaningful factors to effect perceived safety behavior, and safety knowledge & safety motivation were related to safety compliance & safety participation.

In field of Aviation Maintenance, honest and expedite voluntary report of potential hazard provide airworthiness aircraft by eliminating or avoiding from dangerous factors of aircraft. Although it supports for safety flight, voluntary incident reporting system consist of Aviation practitioner and require cooperation of practitioner due to there are no forcibleness. These occur when positive safety culture and report culture are settled. In this regard, this study firstly identify the current status of Aviation Safety Reporting System in Korea. Then, this article also find out the level of reporting culture of the AMT(Aircraft Maintenance Technicians) and problems in reporting system. Finally, suggestions on the model of positive safety reporting culture in a field of aircraft maintenance.

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.

The physical and mathematical foundations of the heat-shielding composite materials functioning under the conditions of aerodynamic heating of aircraft, as well as under the conditions of the point effect of high-energy radiation are considered. The problem of deformation of a thin shallow shell under the action of a local temperature field is approximately solved. Such problems arise, for example, in the case of local destruction of heat-protective coatings of aircraft shells. Then the aerodynamic heating acts directly on the load-bearing shell of the structure. Its destruction inevitably leads to the death of the entire aircraft. A methodology has been developed for the numerical solution of the entire complex problem on the basis of economical absolutely stable numerical methods. Multiple results of numerical simulation of the thermal state of the locally heated shallow shell under conditions of its thermal destruction at high temperatures have been obtained.

In order to advance into the MRO industry, the Aviation maintenance organization with suitable for the standards for personnel, facilities and operations should be first approved by FAA and EASA. The purpose of study is designed to arrange the standards required for personnel, facility, operation rule for approval of Repair Station maintenance organizations certified by FAA PART 145 of the US Federal Aviation Regulation. Also to consider the following differences through the comparative analysis with domestic AMO certification of the information in the Management, Maintenance Process, and Quality System for approval of maintenance organization authorized, the additional EASA PART 145. As a comparative analysis on maintenance organization certification in the country between FAA and EASA, this study could show us that domestic maintenance organization, certified manual contents are used by applying just many of the FAA system. And we could know that as part of the EASA maintenance organization certification process, airmen personnel were relatively systematically segmented and controlled. For domestic maintenance organization certification, operational as policy implications we would like to present policy implications such as the implication of rating system of Aviation Mechanic License like EASA, the financial support of the training center to resolve the shortage of the FAA or EASA license holders, operational organization as "CAMO" for systematic aviation mechanic certified system should be required, continued construction of hangar or MRO for airworthiness repair under Governmental support, and varied application of DER system from FAA accordingly.

Domestic and foreign aviation industries showed steep growth along with rapid increase in aviation demand, but the industries got directly hit by COVID-19. Now, with the recovery of daily life, aviation demand is gradually increasing, too. However, the risk of aviation accidents also increases proportionally to the increasing demand for aviation. Although it is a point that safety management needs to be actively conducted to prevent safety accidents resulted from the growth of aviation industries, research on safety culture and organizations is not sufficiently done in terms of the depth and scope of it despite the importance of the discussion. Studies in various areas have reported that an organization's safety culture forms the group's safety atmosphere and then results in the workers' safety behavior. Accordingly, this study examined the effects of safety culture in an organization on the safety behavior of its members who are aircraft maintenance technicians. The results of this research can be summed up as follows: first, it has been found that the roles of the person in charge grounded on clear goals and guidelines for the organization's safety policy influence the technicians' attitudes. Second, the important factor in the technicians' safety observance is that the attitude to follow safety rules when performing aviation maintenance raises their awareness of safety, for instance, following standard operation procedures or wearing personal equipment for protection. Third, their attitudes have positive effects on safety participation, and consequently, their intention to comply with safety rules is shown as an active action to achieve the ultimate goal of safety behavior.
