For DHC-8 variants I can only see 2022-056, 031.
There's at least two dash-8 engine shut down events in 2022 that don't rate a mention in the ATSB files, a bit like the lack of investigation into the multiple 717 engine shut downs. Using the ATSBs report list to figure out who's having the most incidents is a waste of time, at least half of the serious occurrences I've witnessed lately have not appeared. Anyone who was in the business last year knows QLink Dash-8s were having a horror run with reliability. Rex wasn't far behind, but still fared better. Both QLInk and Rex are suffering the same issues, punching out new routes without the fleet spares to back it up. You could probably say all the airlines are having the same issues with reliability, as all of them have had horror cancellation rates in 2022, except probably Rex, which kept it fairly low with its flexibility.
