Certification of an air navigation service provider

Last update

The provision of air navigation services in the European Union (EU) is subject to certification.

The certification procedure applies to any organisation that wishes to be certified as an air navigation service provider.

The application for certification must be sent to the Directorate of Civil Aviation (Direction de l'Aviation Civile – DAC).

Who is concerned?

Organisations that provide air navigation services.


The DAC must receive the application for certification at least 9 months before the start date of the activity.

How to proceed

Filing an application

Applicants must complete, sign and date 2 forms: DAC-NSA Form 105-1 and DAC-NSA Form 105-2.

They must then send these forms to the DAC.

Application processing time

Within one month of receiving the application for certification, the DAC will send a confirmation of receipt to the applicant by registered letter.

During the subsequent 30 working days, the DAC will determine the verification procedure and activities and send a notification to the applicant.

The DAC will check:

  • compliance with all safety regulations in accordance with the provisions of European legislation;
  • the documents submitted with the application file.

The DAC will conduct one or more certification audits. This is a systematic, independent and documented procedure to gather the supporting documents and objectively assess them with the aim of ascertaining the degree of compliance with the requirements.

If the certification audit does not find any disparities, the DAC will issue an air navigation service provider certificate.

Duration of validity

The certificate is valid for an unlimited duration.

The certificate will remain valid as long as its compliance with Annex III – Part-ATM/ANS.OR.A 025 of Regulation (EU) 2017/373 can be established.

All air navigation service providers are subject to ongoing oversight by the DAC based on an annual audit plan outlined individually and shared in advance.


Should the provider fail to fulfil its obligations, and based on the seriousness of the wrongdoing, the DAC may limit, suspend or revoke all or part of the certificate, while ensuring the continuity of the services, provided that safety is not compromised.
