Propulsion Systems & Aircraft Certification
NEW: Join our Canadian Greener Aircraft Certification Initiative
Transport Canada (TCCA) Design Approval Representative (DAR): Powerplant Installations, Engines & Noise
BAC Aerospace provides national-level expertise in aircraft certification and engineering services to support aeronautical industry clients in obtaining Transport Canada (TCCA) certification of their type design or a design modification (STC). Our specialty is aircraft propulsion and all associated powerplant subsystems for general aviation and transport category airplanes and helicopters.
Our founder is the only Transport Canada DAR to have worked for Transport Canada itself as a National Aircraft Certification propulsion expert. This scarce expertise, previously available only to major OEMs, is for the first time being offered in Canada to small and medium aviation companies. Having worked on most key propulsion system installation projects undertaken in Canada this century, as well as on 100+ STCs projects, on both the TCCA and the industry side, he can now help you.

Frequently asked questions
What is aircraft certification?
Aircraft certification is the structured process of showing the design complies with the applicable airworthiness and environmental regulatory design standards. This formal process includes design evaluations, analyses, testing, inspections and other means of compliance.
What is DAR?
Design Approval Representative, or a DAR, is a subject matter expert granted the delegation of authority on behalf of the Department of Transport Canada, to make findings of compliance within the scope of their discipline and (when authorized) approve changes and repairs to aircraft or engine type designs.
Why do I need a DAR?
Canadian Aviation Regulations CAR 521 require any company applying for an approval of a new aircraft type certificate (TC), or an aircraft modification (STC), to have, or have access to, the technical capability to conduct the design analyses and tests required to demonstrate the conformity of the aeronautical product with its certification basis.
Do you deal with cabin conversions or antenna installations?
At BAC Aerospace our mission is to be the foremost independent aerospace company in Canada in the field of airplane, helicopter and eVtol propulsion, including piston, turboprop, jet, electric and hybrid-electric. However, if you are looking for expertise in other areas such as cabin conversions, antennas, etc., we'll be glad to refer you to delegated experts best suited for your project.
