Scope
This section provides a summary of the number and rate of accidents involving Air Operator Certificate (AOC)
holders per EASA MS. Within the data, AOC holders have been assigned to the State that granted the AOC. The
purpose of this chapter is to consider, in an anonymous way, the safety level of operators and states. The in‑
formation in this chapter will also enable states and individual AOC holders to assess their high‑level safety
performance against those of other EASA‑MS AOC holders.
For the purposes of this chapter, the accident rate has been calculated using the number of accidents and the
number of movements that each AOC holder has conducted using fixed‑wing aircraft for the period 2011 to 2014.
It is also worth clarifying two relevant agreements in force between EASA‑MS relating to the issuance of an AOC
to assist in the understanding of this analysis. The agreements and manner in which accidents have been allocat‑
ed with respect to these EASA‑MS was calculated is as follows:
§
§
An agreement between Liechtenstein and Switzerland allows Switzerland to issue an AOC on behalf
of Liechtenstein. As a result, AOC holders who were licenced under this agreement have been includ‑
ed in Liechtenstein’s data and not that of Switzerland;
§
§
Only those occurrences that have been classified as accidents as defined in ICAO Annex 13 have been
included in this part of the analysis. Furthermore, accident and movement data on aeroplanes owned
by an AOC holder from one of the EASA MS that were leased to an AOC holder operating under an
AOC from a non‑EASA MS have been excluded. All of the AOC holders included within the EASA‑MS
accident rate operated at least 1,000 flights over the period under consideration.
This is the first time that this depth of analysis has been presented in the Annual Safety Review. It could not have
been completed without the assistance of the Network of Analysts in providing missing movement and flight
data for approximately 40 percent of AOC holders who experienced accidents. This assistance reduced the gap
to around 11% and has ensured the accuracy of the accident rates presented in this chapter.
Number of accidents
according to State
This analysis covers a total of 209 EASA MS‑licensed AOC holders with data allocated by AOC State of issuance.
The total number of accidents involving AOC holders within each State was then calculated, which is summarised
in Table 3. These figures do not take into account an AOC holder’s exposure to accidents in relation to the num‑
ber of flight hours or the number of movements they flew.
