Request a supplemental type certificate for an aeronautical product

A Supplemental Type Certificate (STC) is a document issued by Transport Canada to approve a change to the type design of:

  • an aeronautical product identified in the document by a single serial number
  • several aeronautical products of the same type or model, approved under a single type certificate and identified in the document by their serial numbers
  • several aeronautical products of differing types or models, approved under separate type certificates and identified in the document

Changing the type design of a product can be easy or complex, so the scope of work will depend on the complexity of the design change.
