Specialty Design & Engineering

Where innovation takes flight.

As a Transport Canada Design Approval Organization (DAO), Chorus’ Voyageur Aerotech subsidiary specializes in providing in-house design and certification services to deliver customer requirements. This includes Repair Design Approvals (RDAs) and Supplemental Type Certificate (STC) approvals for aircraft modifications, reconfigurations, and part replacements.

Our engineers coordinate all design approval requirements for delegations including structures, systems, avionics, interiors, electrical, and flight testing. The team becomes fully engaged in all phases of MRO activities, from technical support for general maintenance activities to the creation of custom designs, requiring airworthiness approval, including Supplemental Type Certificate (STC) approvals.

We work closely with clients and clients’ regulatory authorities to understand their needs, obtain the appropriate approvals, and ensure seamless transition from concept to certification to operation.
