There has been increasing emphasis on the importance of collecting and analyzing safety data to achieve effective aviation safety management. Although US and Europe has been working diligently on advances of safety information for multiple decades, it has been less than a decade since South Korea first established the mandatory incident reporting system in 2009, which encompasses 45 categories of aviation incidents. In this study, collection of past eight year incident events are reviewed, and analysis on the most prevalent category – Rejected Takeoff (RTO) is conducted. RTO incident not only addressed nearly 50% of all incident events, but has also been increasing in recent years, especially among low-cost carriers (LCC). Based on the common safety concern shared by the national aviation authority and aviation industry on the wide adoption of short turnaround time, association between scheduled turnaround time (STAT) and RTO was analyzed using two-sample test of Poisson rate parameters. The result shows that difference between legacy carrier and LCC is statistically significant in general. When flights were further grouped by STAT, difference between the legacy and low-cost carriers in 30 minute STAT subgroup was statistically significant, where LCC exhibiting more than 600% increase in RTO rate compared to legacy carriers. With nearly 70% of LCC flights scheduled with STAT of 35 minutes or less, the author concludes that unrestricted application of minimum STAT regardless of the characteristics of airports and operators needs to be revisited, and more adaptive approach is needed to achieve higher level of safety assurance.
