Naturally, the ever-growing number of drone operations conducted worldwide carries with it an increase in the number of safety-related incidents and occurrences. The reporting and subsequent investigation of unmanned aircraft system (UAS) accidents and serious incidents seems like a proven solution towards improving operational safety. Such procedures also stem from the fact that UAS are of recognized as aircraft – and aircraft accidents and serious incidents are subject to obligatory investigation. From a technical perspective, a key issue concerns discrepancies in the investigation process as there are significant differences between manned and unmanned aviation operations. From a regulatory perspective, one key question is to what extent should it be obligatory to conduct independent technical investigation of occurrences involving UAS? Such occurrences are not only accidents and serious incidents that involve both UAS and manned aircraft, where “traditional” rules of conducting a full and independent technical investigation apply – the majority occurrences involve only UAS that were either destroyed, damaged or acted as a hazard to third parties. The method of study comprised of content analysis of existing legislation. Current doctrines were confronted with existing regulations, documents, materials, safety reports and statistics. Results of the study shows that the extension of regulations created for manned aviation accident reporting and investigation may not be enough, and certain improvements are necessary, e.g. to standardize the reporting of occurrences and the criteria to conduct a formal accidents and serious incidents investigation. It is also reasonable to take actions aimed at raising awareness among UAS users of the need to report accidents and serious incidents, as well as engage them in the investigative process. The lack of standardization in this field has resulted in the lack of data that is “good enough” to indicate the main causes and factors that contribute to UAS accidents.

自然，全球范围内进行的无人机操作数量不断增加，与安全相关的事件和事件的数量也随之增加。无人机系统 (UAS) 事故和严重事故的报告和后续调查似乎是提高运营安全性的行之有效的解决方案。此类程序还源于 UAS 被视为飞机这一事实——并且飞机事故和严重事故征候必须接受调查。从技术角度来看，一个关键问题涉及调查过程中的差异，因为有人驾驶和无人驾驶航空运营之间存在显着差异。从监管的角度来看，一个关键问题是，在何种程度上必须对涉及 UAS 的事件进行独立的技术调查？此类事件不仅是涉及 UAS 和有人驾驶飞机的事故和严重事故征候，其中适用进行全面和独立技术调查的“传统”规则——大多数事件仅涉及 UAS 被摧毁、损坏或构成危险第三方。研究方法包括对现有立法的内容分析。当前的学说面临着现有的法规、文件、材料 在适用进行全面和独立技术调查的“传统”规则的情况下——大多数事件仅涉及被摧毁、损坏或对第三方构成危害的无人机。研究方法包括对现有立法的内容分析。当前的学说面临着现有的法规、文件、材料 在适用进行全面和独立技术调查的“传统”规则的情况下——大多数事件仅涉及被摧毁、损坏或对第三方构成危害的无人机。研究方法包括对现有立法的内容分析。当前的学说面临着现有的法规、文件、材料、安全报告和统计数据。研究结果表明，为载人航空事故报告和调查制定的法规的扩展可能还不够，需要进行某些改进，例如规范事件报告和进行正式事故和严重事故征候调查的标准。采取旨在提高 UAS 用户对报告事故和严重事件的必要性以及让他们参与调查过程的意识的行动也是合理的。该领域缺乏标准化导致缺乏“足够好”的数据来表明导致无人机事故的主要原因和因素。
