The Transportation Safety Board of Canada is the organization that (among other things) investigates aviation accidents.
I wanted to look up a specific investigation so I proceeded to their website. I knew the exact report number, however the report was not available on the website.
I decided to contact them via their contact form and asked them if I could get a copy of the report (and I cited the report number).
5 days later I got an e-mail back from their Public Affairs Advisor with a copy of the report in PDF format. I was actually quite surprised to get a reply back this soon (and with the information I requested).
Just because a report isn’t available on their site, doesn’t mean you can’t ask for it (and get it!).
I am trying to read up on as many accident reports as possible. I find it an invaluable resource into learning what can “go wrong” when your in the air. You can always learn from other peoples mistakes!
