Over the years, the aviation community has focused its efforts on minimizing the risk aircraft face, such as human errors or technical issues. Whether with safety improvements, technological developments or stricter regulations, that path has always been the way towards the future. Therefore, airline operators must be aware of everything surrounding its operations, particularly the hazards that may compromise the normal safety levels. Following this, euroAtlantic airways felt the need to review its reports related to the Safety Risk Management process and to verify if it was still optimized or if it could be replaced by another method available in the market that could better serve the needs of the company. To do so, a feasibility study to convert the operational risk management process of reports into Bowtie methodology was implemented. It was carried out a bibliographic research on safety management system, hazard identification and risk assessment to better understand the processes previously implemented in the company. A Bowtie diagram for hard landing was created. Then, a real event of a hard landing reported in the company’s IQSMS, considered to be a crucial incident for the company’s operation, was analysed using EAA’s current method and the Bowtie methodology. The results of both analyses were then compared and revealed that even though the Bowtie methodology is a well-structured and recognized method within the industry, it is too complex for the reality of the company and its operation. It was concluded that the current method used, with specific upgrades in terms of the database, can continue to play its role. In the end, improvements were proposed to the system currently established, including updates in the database for the event’s categorization, as well as the introduction of the Bowtie methodology for analysing critical events like, for example, the hard landing.
