Dear Mr McCashin
Decision on information request
In relation to your request dated 1 December 2022, for the fol owing information:
1. Provide process documents for TAIC investigations of an incident.
TAIC Investigations progress through a series of phases per TAIC’s investigation
methodology. Each phase has a discreet set of tasks that enables us to make evidence-
based findings that have been comprehensively reviewed and evaluated. The
investigation process has eight phases. An overview of each phase and the tasks
associated with them are presented in the attached document.

2. Does TAIC assess to see if the operator suffered a sudden medical event prior to the
incident such as cardiac, stroke, or clot?
The Commission considers medical events as a matter of course in al investigations. For
example, post-Mortem results are obtained routinely when there is a fatality of a person
involved in a safety-critical role. The Commission employs a medical consultant
specialising in transport safety to review al medical evidence gathered as part of the
inquiry, the review may result in a finding or recommendation if we believe it may lead to
improvements in future transport safety.
Please contact our Support Services Officer at [email address] if you wish to
discuss this response.
If you are unhappy with our handling of, or decision on, your information request, you may
make a complaint to the Ombudsman. However, please talk to us first to see if the issue can
be resolved.
