Air transportation occurrence data

Dataset from January 1995

With a view to advancing transportation safety, the TSB is publishing data from its Aviation Safety Information System (ASIS) on reportable accidents and incidents (which together are called occurrences) for use by industry and the public. The TSB gathers the data in the course of its investigations and uses it to analyze safety deficiencies and identify risks in the Canadian transportation system.
