Founded in Ontario Canada in 2008, Abbott Aerospace started helping modification programs and aircraft startups with composite structures development. As we grew we added new competencies and experience and now we cover clean sheet configuration to certification management of composite and metallic structures, mechanical systems, landing gear and loads engineering.

Within each discipline we have broad knowledge and operate from kit aircraft to part 25 commercial aircraft. We have also gained experience of unique platforms such as powered parachutes, wing in ground effect vehicles, supersonic transport aircraft and semi dirigible flying wings.
