THE EUROPEAN COMMISSION

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 216/2008 of the European Parliament and of the Council of 20 February 2008 on common rules in the field of civil aviation and establishing a European Aviation Safety Agency, and repealing Council Directive 91/670/EEC, Regulation (EC) No 1592/2002 and Directive 2004/36/EC (1), and in particular Article 8b(6) thereof,

Having regard to Regulation (EC) No 550/2004 of the European Parliament and of the Council of 10 March 2004 on the provision of air navigation services in the single European sky (2), and in particular Articles 4 and 6 thereof,

Having regard to Regulation (EC) No 551/2004 of the European Parliament and of the Council of 10 March 2004 on the organisation and use of the airspace in the single European sky (3), and in particular Article 6(7) thereof,

Whereas:

| (1) | Commission Implementing Regulations (EU) No 1034/2011 (4) and (EU) No 1035/2011 (5) lay down requirements on safety oversight in air traffic management and air navigation services and common requirements for the provision of air navigation services, respectively. Those latter requirements are to be complied with by the service providers concerned in order for them to be issued the certificates referred to in Article 7(1) of Regulation (EC) No 550/2004 and Article 8b(2) of Regulation (EC) No 216/2008. Those Regulations also lay down requirements concerning the competent authorities, which are responsible for issuing those certificates and exercising oversight and enforcement tasks, in accordance with Article 4 of Regulation (EC) No 549/2004 of the European Parliament and of the Council (6), Article 2 and Article 7(7) of Regulation (EC) No 550/2004 and Articles 10 and 22a of Regulation (EC) No 216/2008. |

(1)

Commission Implementing Regulations (EU) No 1034/2011 (4) and (EU) No 1035/2011 (5) lay down requirements on safety oversight in air traffic management and air navigation services and common requirements for the provision of air navigation services, respectively. Those latter requirements are to be complied with by the service providers concerned in order for them to be issued the certificates referred to in Article 7(1) of Regulation (EC) No 550/2004 and Article 8b(2) of Regulation (EC) No 216/2008. Those Regulations also lay down requirements concerning the competent authorities, which are responsible for issuing those certificates and exercising oversight and enforcement tasks, in accordance with Article 4 of Regulation (EC) No 549/2004 of the European Parliament and of the Council (6), Article 2 and Article 7(7) of Regulation (EC) No 550/2004 and Articles 10 and 22a of Regulation (EC) No 216/2008.

| (2) | The requirements set out in Implementing Regulations (EU) No 1034/2011 and (EU) No 1035/2011 serve in particular to implement, at an initial stage, the essential requirements concerning the provision of air traffic management and air navigation services (‘ATM/ANS’) set out in Regulation (EC) No 216/2008, in particular to ensure compliance with Articles 8b and 22a of Regulation (EC) No 216/2008 and Annex Vb thereto and to allow the commencement of standardisation inspections in accordance with Article 24 of Regulation (EC) No 216/2008. |

| (3) | The requirements set out in Implementing Regulations (EU) No 1034/2011 and (EU) No 1035/2011 should now be complemented and updated, in light of technical progress. It should also be clarified that, for service providers to be issued and retain a certificate, or to make a declaration, in accordance with this Regulation, they must comply, and continue to comply, with those requirements as well as with the essential requirements referred to in Article 8b(1) of Regulation (EC) No 216/2008. In addition, consistency should be ensured between those requirements and the requirements set out in Commission Implementing Regulations (EU) No 965/2012 (7), (EU) No 1178/2011 (8), (EU) No 139/2014 (9) and (EU) 2015/340 (10), thus moving towards a ‘total system approach’, which entails a logical and technologically consistent approach across the various domains. Therefore, the requirements set out in Implementing Regulations (EU) No 1034/2011 and (EU) No 1035/2011 should now be laid down in one single Regulation and Regulations (EU) No 1034/2011 and (EU) No 1035/2011 should be repealed. |

| (4) | Common rules for the certification and oversight of service providers concerned are essential to increase the Member States’ confidence in each other’s systems. In order to ensure the highest level of safety and security, uniform requirements for the provision of services and their oversight should therefore be strengthened. That should ensure the safe, high-quality provision of services for the purpose of air navigation and the mutual recognition of certificates throughout the Union, thereby increasing freedom of movement and improving the availability of those services. |
