About CertifyNation

In 2011, CertifyNation® was founded as an aerospace engineering services company specializing in supplemental type certificates (STCs) for aircraft modifications. CertifyNation was acquired in 2016 by The Angelus Corporation, a global product and services provider for aerospace and defense industry solutions.

CertifyNation’s mission is to make its customers’ jobs easier. The STC process is lengthy, complex, and can differ from country to country, so we crafted a comprehensive suite of start to finish aircraft certification services to simplify and accelerate the process. Our engineering team has decades of international certification and engineering experience, with the ability to provide services that address every aspect of the certification process. We approach each project with our mission in mind, and are highly focused on meeting customer needs and project deadlines, while also building strong customer relationships and advancing trust and confidence.
