Occurrence Categories
In order to assist in the identification of particular safety issues, one or multiple occurrence categories were as‑
signed to ATM accidents and serious incidents involving the EASA MS Aerodromes. This was done using the
CICTT occurrence categories, which are listed in Appendix 1. The occurrence categories, in addition to ADRM,
that were assigned to Aerodrome accidents and serious incidents are shown in Table 46.

Runway Excursions
A Runway Excursion is defined as an aircraft veering off the side or overrunning the end of the runway surface
during take‑off or landing. The European Aviation Safety Plan (EASp) identifies Runway Excursions as being one
of the key operational safety risks for Commercial Air Transport (CAT) aircraft. While figures for Runway Excur‑
sions at EASA MS Aerodromes are shown here, figures for runway excursions involving CAT Aeroplanes are to
be found in Chapter 5.
In total, there were 135 Runway Excursion accidents and serious incidents at EASA MS Aerodromes between 2010
and 2014, with 25 of these occurring in 2014. Figure 48 shows the total number of Runway Excursions per year,
broken down by occurrence class. Unlike Table 46, Figure 48 includes Runway Excursions where the Aerodrome
occurrence category has not been assigned. It can therefore be assumed that the Runway Excursion did not re‑
late to the aerodrome but more probably to factors involving aircraft operations or air traffic control.
