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.
Accidents and incidents are reported in accordance with the TSB Regulations that were in effect at the time.
The dataset is composed of 5 tables in CSV format.
Content of the dataset
Some data collected by the TSB and recorded in ASIS will be excluded from the public database to protect third-party, personal and privileged information, in accordance with the Canadian Transportation Accident Investigation and Safety Board Act, the Privacy Act and the Access to Information Act.
The data in text fields is provided in English and French, while free-text fields contain data in the language in which it was entered. Some of the data is from sources not subject to the Official Languages Act and are therefore available only in the language in which it was provided.
The data are described in the data dictionary for this dataset, which is available in CSV [89 kb]
The ASIS dataset is released on or soon after the 15th of each month, and contains data from January 1995 to the last day of the month preceding its release.
The dataset is for information purposes only. The user of the data assumes all responsibilities for its use and for verifying its completeness and accuracy for both critical and non-critical uses and applications.
The data in ASIS has been collected by the TSB from third-party sources believed to be reliable. As many occurrences are not formally investigated by the TSB (see the Occurrence Classification Policy), information pertaining to some occurrences may not have been validated. Consequently, this data is provided on an as-is basis, and the TSB does not warrant its quality, accuracy, reliability, or completeness.
In no event will the TSB be liable for any direct, special, indirect, consequential or other damages, however caused, arising out of or in connection with the use of any data contained in this dataset. If you find any errors, please report them to firstname.lastname@example.org.
