Occurrence Categories
In order to assist in the identification of particular safety issues, one or multiple occurrence categories were
assigned to helicopter accidents involving EASA MS operators. This was done using the CICTT occurrence cate‑
gories, which are listed in Appendix 1.
Table 13 shows the number of accidents and serious incidents per occurrence category. The 2014 numbers
have been compared to the yearly average of the preceding decade. In 2014, there were no LOC‑I occurrences.
In addition, when compared to the average of the preceding decade only abnormal runway contacts (ARC) had
a significantly higher number in 2014.
