25.11.2011 Official Journal of the European Union L 310/3 COMMISSION IMPLEMENTING REGULATION (EU) No 1216/2011 of 24 November 2011 amending Commission Regulation (EU) No 691/2010 laying down a performance scheme for air navigation services and network functions (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the functionning of the European Union, Having regard to Regulation (EC) No 549/2004 of the European Parliament and of the Council of 10 March 2004 laying down the framework for the creation of the single European sky (the framework Regulation) (1), and in particular Article 11 thereof, Whereas: () ) Commission Regulation (EU) No 691/2010 laying down a performance scheme for air navigation services and nework functions and amending Regulation (EC) No 2096/2005 laying down common requirements for the provision of air navigation services (%) provides for Key Performance Indicators (KPIs) and binding targets on the key performance areas of safety, environment, capacity and cost-efficiency. The safety KPIs for national or functional airspace block (FAB) target setting set out in Annex 1 to Regulation (EU) No 691/2010 are: the effectiveness of safety management as measured by a methodology based on the ATM Safety Framework Maturity Survey; the appli- cation of the severity classification of the Risk Analysis Tool to allow harmonised reporting of severity assessment of Separation Minima Infringement, Runway Incursions and Air Traffic Management (ATM) Specific Technical Events; and the reporting of just culture. Pursuant to Annex 1 to Regulation (EU) No 691/2010, those safety KPIs should be further developed jointly by the Commission, the Member States, the European Aviation Safety Agency (EASA) and the European (6) ) Article 1 Regulation (EU) No 691/2010 is amended as follows: (1) Article 14 is amended as follows: Organisation for the Safety of Air Navigation (Euro- control) and adopted by the Commission prior to the first reference period. To this effect the Commission established a Working Group consisting of representatives from EASA, Euro- control and the Commission (so-called E3-Task Force). That working group produced a technical report entitled “Metrics for Safety Key Performance Indicators for the Performance Scheme”. That report was further developed on the basis of the comments received from Member States and the stakeholders and constitutes the technical concept for this Regulation and its associated Acceptable Means of Compliance (AMC) and Guidance Material (GM). Work already done in respect of other initiatives such as EASA Safety Plan and Eurocontrol's Risk Analysis Tool and Safety Framework Maturity Survey should be taken into account in the development of safety KPIs. Experience gained from the gradual implementation of the performance scheme shows that the time allocated to the Commission for the assessment of revised performance targets should be increased in view of the workload generated by the detailed assessment of performance plans and in order to conduct the necessary dialogue with the national supervisory authorities and to ensure an appropriate justification of the results of that assessment. Regulation (EU) No 691/2010 should therefore be amended accordingly. The measures provided for in this Regulation are in accordance with the opinion of the Single Sky Committee, HAS ADOPTED THIS REGULATION: (a) In paragraph 1, the words ‘two months’ are replaced by ‘four months’; (b) In paragraph 2, the words ‘two months’ are replaced by ‘four months’; 96, 31.3.2004, p. 1. 0] L 0J L 201, 3.8.2010, p.1.
