3.2.6 The total number of reported safety occurrences are shown on Figure 28, has increased,
showing a continuous trend for the past 6 years, although the number of safety
occurrences still under investigation (9%) remains an area of concern.

3.2.7 The number of States reporting safety incidents has not shown improvement over the last
5 years. Out of the 43 ECAC States, 14 did not report in 2008, 9 of them are
EUROCONTROL Member States (Armenia, Bulgaria, Croatia, Luxemburg, Malta,
Monaco, Slovenia, Turkey and Ukraine) Furthermore out of the 29 States which reported,
5 of them reported less than 5 incidents in 2008.
3.3 Safety Maturity Surveys
3.3.1 In 2002 the EUROCONTROL Agency started conducting surveys of ECAC States’ ATM
Safety Regulators and ANSPs to identify how well ATM safety requirements were being
met. The participation in the surveys was voluntary and based on questionnaires
developed by the Agency. The answers to the questionnaires were used to score the
different organisations according to the Safety Maturity Survey Framework methodology
approved by the EUROCONTROL Provisional Council.
3.3.2 In 2003 the EUROCONTROL Provisional Council set an objective for each Member
State to reach, by 2008, a maturity score of at least 70%. Since then the safety maturity
surveys have been carried out six times and the results were published in the annual ATM
Safety Maturity Survey reports. Due to confidentiality restrictions only de-identified
maturity scores have been published in Performance Review Reports.
3.3.3 Despite the voluntary character of the surveys, in 2009, 42 ANSPs and 40 ATM Safety
Regulators from 46 States have returned answers to the corresponding questionnaires.
However, the number of interviews conducted after the collection of the answers and
aimed at confirming the quality of the surveys, was less than in 2008 with 34 ANSPs
interviewed and 31 ATM Safety Regulators in total.
3.3.4 Figure 29 shows that in 2009 11 ATM Regulators and 7 ANSPs have not yet met the
agreed safety maturity level of 70%. Clearly, significant effort remains to be made in
these Member States to meet safety maturity targets.

ANSP RESULTS
3.3.5 In 2009 ANSPs have reported steady progress; There are 19 ANSPs who have shown
improvements overall, some of these significantly high with one of them showing an
improvement of 20% and seven being over 5%. The overall average maturity for ANSPs
is now 82%, an increase of 27% since 2002.

REGULATOR RESULTS
3.3.6 The Regulatory picture is more positive than last year, in that there have been no
decreases in maturity since 2008. Three ATM Regulators have reported an improvement
of 11%. This significant improvement was driven by the implementation of international
safety requirements (ICAO, EUROCONTROL and EC) in their National Regulations.
There are still 11 ATM Safety Regulators showing below the 70% target. However, 3 are
only marginally below the 70% level. Of the 9 remaining ATM Safety Regulators, 3 have
