The aftermarket modifier ecosystem needed a 'home' to discuss our challenges and best practices, to improve our services by delivering a common message to the market. Together, we have the objective to shape the future of the STC in the aviation world.

We believe that OEMs will also benefit from becoming members of IAMA, which is open to all modification providers.
