How to apply
Applications may alternatively be submitted by email to stc [at] easa.europa.eu, this might however lead to slightly longer processing times.
Please support the paperless management of applications by submitting applications to us electronically only.
If this is your first application to EASA and you do not have an EASA applicant account, you will need to submit a copy of articles of incorporation of the entity or business registration stating the company name, business registration number and legal seat of the company.
In case the applicant is not a company but a natural person, a copy of the person’s ID or passport needs to be provided.
Documents can be uploaded using the EASA file box.
Specific technical documents shall be provided directly to the person responsible for investigating your application. The individual contact details will be communicated to you upon EASA application acceptance.
The exchange and review of documents may also be conducted using SEPIAC – contact sepiac-support [at] easa.europa.eu or your PCM to understand whether your project can be managed using SEPIAC and request the access to the tool.
Applications from U.S., Canada and Brazil
EASA will wait for the authority forwarding letter prior to registering the application. A copy of the Certifying Authority (CA) STC to be validated is required together with the application form.
