This study analyzes the influential factors and patterns associated with death from aircraft accidents and incidents using data mining techniques. To this end, we used two datasets for aircraft accidents and incidents, one from the National Transportation Safety Board (NTSB) and the other from the Federal Aviation Administration (FAA). We developed our prediction models using the decision tree classifier to predict death from aircraft accidents or aircraft incidents and thereby derive the main cause factors and patterns that can cause death based on these prediction models. In the NTSB data, deaths occurred frequently when the aircraft was destroyed or people were performing dangerous missions or maneuver. In the FAA data, deaths were mainly caused by pilots who were less skilled or less qualified when their aircraft were partially destroyed. Several death-related patterns were also found for parachute jumping and aircraft ascending and descending phases. Using the derived patterns, we proposed helpful strategies to prevent death from the aircraft accidents or incidents.

Recently, in an effort to decrease aviation accident worldwide, there has not been any significant decline of the aviation accident rate. Therefore, in the international society, it is more focused on removing risk factors based on data collected and analyzed, in order to improve the aviation safety. This paper introduces on the characteristic of ECCAIRS 5 which become the standard for the worldwide aviation safety reporting and data exchange system. Also, using domestic aviation accident data collected during last 10 years(from 2003 to 2012), we analyze the distribution of the aviation accidents/incidents, annual and monthly aviation accident rate, flight phase, and occurrence category according aircraft type(Fixed/Rotary wing). The analyzation regarding the tendency of aviation accident/serious incident will give the direction to approach the quantitative safety management.

'UAS flight recording system' is a system that is mounted on an unmanned aircraft system consisting of various components and records flight-related data. The data recorded by this system should be used for aviation accident and incident investigations to prevent similar accidents. In particular, for the category of UAS with high operating risk, safety devices close to that of manned aircraft are required, and it is urgent to develop flight recording systems reflecting the characteristics of the UAS to secure airworthiness. This paper highlights the need for UAS flight recording systems for aviation accident and incident investigations and seek a method to derive flight recording system parameters for 'Certified Category' with high operational risk. To this end, Inter-City UAM was used as a concrete use case, and the process of approaching system parameters was devised by assuming accident occurrences and hazards from mission profiles and scenarios. As a result of the study, it was confirmed that parameters could be derived through this process.

Recently, despite of the development of aviation safety, there has not been any significant decline of the aviation accident rate. Therefore, in the international society, it is more focused on removing risk factors based on data collected and analyzed, in order to improve the aviation safety. This research introduces ECCAIRS, which is a program developed by European Union to collect and analyze data regarding risk factors. This is used in Korea since 2010. Moreover, using national aviation accident data collected through ECCAIRS, this research analyzes the distribution of the aviation accidents/incidents, annual and monthly aviation accident rate, flight phase, and division system. The analyzation regarding the tendency of aviation accident/incident will give the direction to approach the quantitative safety management.

국내 전체 조종사 배출 인원은 연 평균 1,200여명을 훌쩍 넘긴 가운데, 이 중 항공기사용업체를 통해 배출된 조종사 인원은 최근 5년 사이 2~3.5배 이상의 증가추세를 보이며 약 650여명 이상을 배출함으로써 전체 인원의 반 이상을 차지하고 있다. 그러나 현행 법령은 비행훈련과정을 운영하는 대학을 포함하여 항공기사용사업의 업무영역을 고려한 등록 요건 및 안전 고려가 부족하며, 비행훈련은 미래의 조종사를 양성하는 중요한 영역임에도 불구하고 훈련프로그램에 관한 요건이 규정되지 않아 비행안전은 물론, 양질의 조종사 인력양성을 위한 제도적 장치가 부족한 상황이다. 본 연구는 최근 발생한 항공기 사고/준사고 및 안전장애 유형을 토대로 항공기사용사업체에 대해 분석하고, 시행중인 비행훈련에 대한 법과 제도, 안전관련 개선방안에 대해 살펴보고자 한다.

The first successful sustained powered flight by Wright Brothers was further extended to the rapid development of aviation technology, that led to transpacific flights, the invention of supersonic planes, and enabled hundreds of people to travel in the space, in addition to the fact that around 10 people had stepped on the moon, all of which were made possible within the very same century. However, on the back side of this most wondrous human technology, the vulnerableness to the aviation accident has been constantly accompanied with, right from the very beginning stage of the aircraft development. Moreover, the development of future aircraft is being focused on the aircraft performance, the increment of the number of passengers aboard and also its speed. In proportion to these phenomena of mega sizing the aircraft, the development of new technology and the increment of air traffic volume, the number of aviation accident is expected to augment, resulting in the enormous loss of human lives and properties. In order to prevent the disastrous aviation accident as such, it is essential to conduct the accident investigation in a specialized, systematic and scientific manner. In search for the method to attain the effective function of the aviation accident investigation organization, in this study, issues were examined as follows: The full-time Board Members and the establishment of an integrated investigation agency, The systematized security of status as an accident investigator, Inclusion of a human factors specialist in the investigator group organization, liability limit of an accident investigator Stipulation of the definition and the investigation scope of an accident and serious incident, along with the main body of conducting the investigation into the accident involving both civil and public aircraft, in the regulations related to the accident investigation.

항공기의 이륙단념(Rejected Takeoff) 사고는 흔히 발생하지는 않지만, 발생하면 큰 사고로 이어지는 경우가 대부분이다. 제트기에 의한 운송서비스가 본격적으로 시작된 1959년부터 2000년 까지의 이륙단념 사고사례를 조사해 본 결과 총 94건이 발생했다. 사고사례 모두가 활주로 이탈로 이어졌고, 그 주요 원인은 이륙결심 속도를 넘어서 조작을 시작했기 때문이라고 미국교통안전위원회(NTSB)에서 발표하였다. 이런 결과는 미국 항공우주국(NASA)의 준사고보고제도(ASRS)에서 조사한 자료에도 비슷한 결과가 나온 바 있다. 따라서 항공기 운항의 기준이 되는 항공기 비행규정(Airplane Flight Manual)을 만들 때 적용하는 미국연방항공법(FAR)상의 이륙단념 전환시간이 국내 현장조종사에서도 적합한 지에 관해 연구하였다.

항공산업의 초창기에는 항공기 안전사고의 대부분이 기술결함으로 인하여 발생하였다. 그러나 항공기술의 발달로 인한 첨단화, 정밀화되면서 기술결함에 의한 사고는 대폭 감소하였지만 인적요인에 의한 사고는 일정한 수준 감소 이후 꾸준하게 유지하고 있다. ICAO따르면 인적요인의 70~80%가 재발 가능성이 존재하며 독자적인 원인이 아닌 위험요소의 복합적작용으로 발생한다고 기술하고 있다. 이를 방지하기 ICAO에서는 항공안전을 위협하는 사고(ACCIDENTS), 준사고(Serious INCIDENTS), 항공안전장애(HINDRANCES)등의 데이터를 수집, 공유, 분석을 통해 항공안전 위해요소를 사전에 제거, 차단할 수 있는 사전예방 시스템의 수립을 권고하고 있으며 이를 위해 국제사회를 중심으로 의무보고제도, 자율보고제도 등이 활발하게 운영되고 있다. 그러나 국내의 경우 운영시스템의 체계화 및 정부, 관련부처의 노력에도 불구하고 일부보고제도만이 정착되어있고 자율보고제도는 사회적 환경, 문화적 요건의 차이 등으로 인하여 활발하게 운영되지 못하고 있다. 따라서 국내 외 안전자율보고제도의 동향을 바탕으로 해당제도의 효율적인 정착 방안을 모색할 필요가 있을 것이다.

Flight tests for aircraft development and certification have higher air accidents risk than other aerospace industries. Accordingly risk identification necessary for risk management in the safety management system is a very important factor in preventing similar air accidents during flight tests. But internationally issued accident statistics are usually confined to commercial transport aircraft and they do not reflect characteristics of flight tests, also databases to hazards identification during flight tests are not established or available in Republic of Korea. Therefore, we identified flight test procedures and traced the major causes of aviation accidents based on the statistics and preventive materials for risk management which were issued by international organizations and advanced countries of aviation. A total of 312 final reports classified as flight test among air accident/incident database held by U.S. NTSB were researched and about 200 flight test hazard were identified. The results of this study will be used as basic data for establishing the safety management system of the national comprehensive flight performance test site.
