About investigations

To advance safety in air, marine, pipeline, and rail transportation, the TSB

  • conducts independent investigations into transportation occurrences;
  • if necessary, communicates important safety deficiencies to those able to address them right away, before an investigation is complete;
  • once investigations are complete, reports publicly on the investigation, the factors that caused or contributed to the occurrence, and the safety deficiencies that need to be addressed;
  • makes and follows up on recommendations designed to eliminate or reduce safety deficiencies found in the course of investigations.

The TSB does not have the mandate or authority to implement specific corrective actions. Such actions are taken by change agents such as regulatory agencies, manufacturers, and operating companies.
