EASA Proposed CM No.: Proposed CM-21.A-B-002 Issue 01 Eligibility for type certificate application
The European Aviation Safety Agency, hereafter referred to as the “Agency”, may receive requests from
organizations to provide technical advice services prior to or outside an actual certification process
conducted within the scope of Part 21. These activities or “pre-application services” are performed by the
Agency on a purely voluntary basis and are regulated by a contract between the Agency and the client. When
a product becomes suffciently mature, an application is submitted to the Agency.
The purpose of this Certification Memorandum is to support applicants, before they submit a TC application
to EASA, in assessing their readiness for such an application. It therefore provides specific guidance for
potential type certificate (TC) applicants in meeting EASA expectations regarding their eligibility and the
related demonstration of capability in the context of certification. When an applicant is not ready, the above
pre-application services may be used as appropriate.
