Brazil issued Decree No. 21,713, which promulgated the Convention on International Civil Aviation (the Chicago Convention) for Brazil. The decree attached the convention text and states that Brazil had signed it in Washington, D.C., on 29 May 1945. By promulgating the convention, Brazil formally integrated the treaty framework that underpins modern international civil aviation rules and cooperation. This act is significant because it reflects Brazil’s post–World War II alignment with emerging global aviation governance and international standards.
