「超輕型載具飛航安全風險因素評估」在找出並評估國內具動力之超輕型載具飛航安全風險因素。本文採用「質性研究」法及「參與觀察法」。資料來源有兩部分；第一部分是民航局紀錄、報章、雜誌及個人過去十年飛行紀錄資料。此部分資料配合IATA分類原則，製作72則案例：人為因素44則、機械因素14則、環境因素10則，組織因素4則。第二部份資料來自對資深飛行者及政府官員的訪談。從這些資料，發現風險因素45項。
用這些風險因素製成風險因素評估卷，在每一因素後加上里克特五等量尺，評估風險因素的風險值「很高」、「高」、「中」「低」或「很低」。訪談卷發出80份，回收70份。有效卷44份。信度Cronbach α：0.98。45項風險因素，平均值均在3.1以上，最高者5.54。事故最重要的原因是：人為因素，依次：機械因素，環境因素，組織因素。
將此研究結果製成「安全查核表」，仿照ALRA模式，在每一項目後加警告號誌，號誌愈多表示風險愈高。以期給超輕飛行者一個「飛行風險的參考」，以提升飛行安全。

The goal of this research: “The Evaluation of the Risk factors of Ultra-light Aircrafts” is to evaluate the risk factors of powered Ultra-light Aircrafts in Taiwan. This study adopted “qualitative research” and “participant observation” methods. The data of this study came from two parts. The first part came from Civil Aeronautics Authority records, newspapers, and personal records from past ten years of flights. With these data, 72 causes were identified. Using IATA´s rules, the causes were classified into 4 major parts: the first causes of accidents is human factors with 44 cases, the second is technical factors with 14 cases; the third is environment factors with 10 cases and the last is organization with 4 cases. The second part of the data came from interviews with the experienced ultra-lights fliers and officers of government. From these data we identified 45 risk factors.

From these 45 risk factors, a questionnaire was designed. In each question the Likert 5 sorts measurement is used to evaluate the risk factors: “very high”, “high”, “medium”, “low”, or ”very low”. There were totally 80 copies distributed with 70 returned. Disregarding the ineffective ones, there were 44 left. The reliability is found to be 0.98. The means of all items are above 3.1. The highest mean is 4.54. The most important cause of accident is human factors, the second is technical factors, the third is environment factors and the last is organization.

From the results of this study, a safety checklist for people who are interested in ultra-light flight is proposed. The checklist follows ALRA as a model to give each risk factor a warning level. The number of warning symbols accompanying each factor indicates relative level of risk. Generally, the greater the number of warning symbols, the greater the risk presented by that factor. It is expected that the proposed safety checklist can provide a reference about the risk of flight of ultra-light aircrafts and promote the flight safety.
