Please use the applicant portal for the application for an ETSO Authorisation.
If the application is accepted, the applicant will receive an acceptance mail with further instructions how to provide documents to the Agency and with the contact details of the Project Certification Manager (PCM) of the project.
Use of Form 34 was discontinued, as the applicant portal provides a standardized way to provide the information in an electronically readable format. Use of Form 35 was discontinued, as the DDP contains all the necessary information provided by Form 35 in the past.
The list of deviations from CS-ETSO (accepted, consulted and rejected) can be found on the Product Certification Consultations page. For deviations processed before the 1st of January 2013 consult the summaries of approved and rejected deviations provided in the download section.
