We have never not gone to an investigation they've asked us to go to, but certainly, although they've always been notified when we're doing an investigation that would have a Transportation Safety Board connotation, occasionally the Transportation Safety Board says that it's beyond their mandate, or that they're not going to send any investigator for that.
Mais même si nous l'avons toujours avisé des enquêtes qui pourraient demander sa participation, le Bureau de la sécurité des transports a parfois indiqué qu'elles ne cadraient pas dans son mandat ou qu'il n'y affecterait pas d'enquêteur.
