About NSA

European Union Member States are required or establish a body as their National Supervisory Authority (NSA) in order to carry out the tasks assigned to such authority under the Single European Sky legislation.

National Supervisory Authorities ensure the supervision of the ATM regulatory framework in all EU Member States. They are in particular responsible for certifying and overseeing air navigation service providers (ANSP).

The NSAs shall be independent of air navigation service providers. This independence is achieved through adequate separation, at the functional level at least, between the NSAs and such service providers. Bulgarian legislation ensures that National Supervisory Authority exercise its powers impartially and transparently.

Republic of Bulgaria has established NSA through amendment of Civil Aviation Act on 1 of January 2012 art. 16c.

The major tasks assigned to National Supervisory Authority in Republic of Bulgaria under the Single Sky legislation are:

  • ANSP certification
  • Ensure compliance with charging principles for air navigation services
  • Application of safeguards under the Interoperability regulation

National Supervisory Authority is responsible for organising and execution of proper inspections and surveys to verify service provider’s compliance with the SES Service Provision Regulation and related common requirements for the provision of air navigation services. The NSAs may decide to entrust carrying out inspections and surveys, which fall within their remit, to qualified entities.

The role and responsibilities of a NSA for the safety oversight of air navigation services (ANS), air traffic flow management (ATFM) and airspace management (ASM) for general air traffic are further detailed in the Commission Implementing Regulation (EU) No 1034/2011 of 17 October 2011 on safety oversight in air traffic management and air navigation services.

Republic of Bulgaria ensures that NSA has adequate human and financial resources to carry out their duties.
