Department of Transport : Civil aircraft registration, inspection and operation files, 1920-1986
This collection consists of central registry files that document the development of policy, its application, the airworthiness of the new types of aircraft being introduced into Canadian airspace, and their individual certification. Files are arranged by the 5008 block and the registration number. For example, 5008-AFF. It should be noted that once an aircraft is struck from the central registry of aircraft, that registration number is assigned to the next aircraft. Therefore, a number of aircraft may have the same registration number.
Note: 535 Reels of information
