Pilots are indispensable and central to the aviation industry, with the relevance of their psychological stress and resultant human errors increasingly recognized as critical. This study aims to meticulously explore the interrelations between psychological stressors and associated factors among helicopter pilots, assessing the consequent effects on potential accidents and incidents. The study comprised active pilots from domestic helicopter airlines, with data collated through both focus group interviews (FGI) and comprehensive surveys. These data were subsequently analyzed using SPSS and AMOS for structural equation modeling. The results reveal that heightened psychological stress in helicopter pilots correlates with an increased incidence of human errors, which in turn, elevates the likelihood of potential safety incidents. Based on these findings, it is proposed that interventions designed to mitigate psychological stress among pilots could significantly reduce human errors and enhance overall aviation safety. This research provides crucial insights into specific ways to improve the operational conditions for helicopter pilots and strengthen the safety protocols within the aviation industry.

Continued efforts to build up Safety Management System(SMS) and to improve its efficiency in airports, to which customers have direct access, are taken for granted due to continuous development of the aviation industry in both quantity and quality and rapid growth of air transportation market. This thesis proposed efficient operation methods of SMS for domestic airport organizations including Incheon International Airport(IIA), the largest airport in South Korea, aiming at strengthening aviation safety from the perspective of airport operators who play a pivotal role in service provider SMS. Those are consolidation of the existing safety management organizations and various improvements to promote voluntary incident reporting system. To draw a proposal for the improvements, conducted a research on domestic safety management status, carried out an analysis on operating conditions and did a research on ICAO regulations, domestic legal system as well as statistics data. Relevant studies and researches were also gathered and analyzed. A search for further improvements can also help increase operational efficiency and promoting a higher-level of safety awareness among operators can establish mature safety culture at airports.

항공안전관리는 항공운용 등에 있어서 승무원, 항공기 및 기타 자원의 안전을 확보하기 위한 항공산업 전반에 대한 관리이다. 국제민간항공기구는 안전한 항공기술의 발전을 위하여 국제 기술표준의 중요성을 인식하고 국제민간항공협약에서 19개 부속서(Annex 19)를 제정하였다. 이에 따라 각 회원국도 국제민간항공기구의 정책에 맞춰 항공법령에 국제표준 및 권고사항을 수용하게 되었으며 2013년 11월 14일부터 적용되는 부속서 19에서는 그간 항공안전에 관한 각국의 의견을 반영하여 항공안전관리체계가 제시되었다. 이 같은 국제적 흐름에 따라 국토교통부는 2012년 1차 항공정책 기본계획으로 사전예방적 안전관리 전략을 추진할 것이라고 공표하였으며 부속서 19의 안전관리에 대한 핵심인 항공안전프로그램(SSP) 및 안전관리시스템(SMS) 등을 통합하여 기술 인적자원 정보공유와 투자우선순위 결정, 항공안전관련 주체들의 협력강화를 하기 위한 정책을 시행 중이다. 부속서 19는 국가항공안전프로그램(SSP), 항공안전관리시스템(SMS), 항공안전감독시스템, 안전정보수집, 공유 및 보호정책에 대한 내용을 포함하며 예방적인 안전관리의 체제로 전환을 유도하고 있다. 항공안전프로그램은 안전 증진을 목표로 정부의 규정과 활동을 통합적으로 관리하는 일련의 활동체계를 의미한다. 본 프로그램의 목적은 항공운송사업자, 항행서비스 공급자, 공항운영자, 훈련 및 정비 기관에서 제공하는 항공 서비스의 허용 가능한 안전 수준을 설정하고 관리하는 것이다. 항공안전관리시스템은 위험정보 통계에 근거하여 예측적인 위험관리가 핵심인바 항공안전관리시스템의 성공적인 운영을 위해서는 풍부한 위험정보의 수집이 필수적이다. 수집되는 정보 중 대형사고는 의무보고제도에 의해 보고를 받게 되지만("항공법" 제49조의 3), 소규모 사고는 자체보고하지 않는다면 진지한 조사가 행해지지 않고서는 알 수 없기 때문에 이에 대한 위험사고 수집이 중요하다고 할 수 있다. 국내 항공교통의 안전확보는 정부의 주요 임무이다. 정부는 국제민간항공기구의 기준과 국내항공법규 요건을 준수하고 안전한 정도를 유지하기 위하여 필요한 전략과 프로세스를 수립 시행하며 이를 지속적으로 개선하여야 한다. 민간항공사는 안전관리의 향상과 안전문화 조성을 위하여 전자적인 안전관리기법을 적용하여 안전제반기능이 구현되도록 노력해야 한다. 항공안전은 항공실무를 토대로 규칙을 제정하여야 하는바 항공안전 규제 사항에 대하여 항공산업계의 의견을 적극 수렴해야 한다. 또한 항공안전 보고제도와 자유로운 정보교환 여건을 조성하여 효율적인 안전관리 실현을 지원해야 하며, 안전과 관련된 문제를 해결하는 과정에서 민간항공사와 공조해야 한다. 항공안전 활동을 위하여 적절한 자원을 배정하고 직원의 교육 훈련을 통해 안전관리에 관한 기량을 유지시켜야 하며, 안전목표의 달성도 평가 및 위험도 평가와 같은 성과기반의 점검과 안전기준 절차이행점검 방식을 병행해야 할 것이다.

In accordance with ICAO SARPs, the states should implement appropriate aviation-related health promotion for airmen subject to an aviation medical examination to reduce future medical risks to flight safety. We aimed to analyze the results of the aviation medical examination to use as objective evidence for establishing an aviationrelated health promotion plan. The results of the final issuance of airmen medical certificate from 2015~2017 were collected from the e-sky computer system. The 30 cases (0.3%) in 2015, 22 cases (0.2%) in 2016, 38 cases (0.3%) in 2017 were unfit for flight duty. The 34 unfit out of the total 90 cases were renewal physical examinations. The cardiovascular disease was most commonly in 11 cases, followed by 8 tumors, 4 psychiatric diseases, 3 ophthalmic diseases, 2 respiratory diseases, 2 neurologic diseases, 2 otolaryngological diseases, 1 endocrine disease and 1 digestive disease. The results of this study can be used as objective data in aviation-related health promotion plan. The health promotion activities based on objective data can contribute to improving aviation safety by improving the lifestyles of airmen.

Reliability of fatigue strength on Aircraft Composites(GFRP) Structures was assessed in this paper. Fatigue strength of GFRP was used through the existing fatigue test data with Monte Carlo method. The S_a-N_f curve of composites fatigue strength was assumed as normal distribution and reliability was analyzed using SSIT model. Fatigue stress was designed IAW ASTM F3114-15 with special safety factor of S_sf=1.2~2.0. Reliability was calculated by analytic method and FORM. Sensitivity for the effect of mean and standard deviation of fatigue strength as well as fatigue stability was evaluated. This result can be usefully applied to reliability and fatigue design for composite structures of light weight aircraft.

Risk Based Oversight is a way of performing oversight, where planning is driven by the combination of risk profile and safety performance. Risk Based Oversight enables prioritization and allocation of State's safety management resources commensurate with the safety risk profile of each service provider. This paper presents the concept of Risk Based Oversight and applies it to the current Korean aviation safety oversight process. In particular, this study presents a method for generating operating profiles, one of the key concepts of Risk Based Oversight. Operations Specifications of Part 121 Airlines can generate operating profiles. In this study, a practical study was conducted to generate the operating profile and scoped DCTs using Part 121 Airlines's Operations Specifications.
