In our previous blog post on civilian aviation accidents, we covered the main search principles for finding files on this topic in our archives. We showed you that records could generally be found in four record groups:
- Department of National Defence fonds: R112 (1923–1936)
- Department of Transport fonds: R184 (1936–1984)
- Canadian Aviation Safety Board fonds: R13086 (1984–1989)
- Transportation Safety Board of Canada fonds: R1009 (1990–present)
