SERTA Company, founded in 1976 by Alain DELUGIN, became an Aeronautical Group in 1998. This Group is composed of national sites like SERTA ASD and A&T Aerospace and international sites like SERTA Polska (Poland) and a company located in India. This group specializes in engineering, design, industrialization and manufacturing of aircraft parts and structures and in assembly and integration of mechanical and composite sub-elements.

In January 2016, in an aeronautical subcontractor market offering strong growth prospects, the group including the A&T Aerospace Company, was taken over by “Industries & Finances” on the occasion of its founder release.

This group is now called AERYA.
