What is criminal is CASA taking so long to get to the stage where they are now concerned.
We are concerned that contrary to the formal declarations made by the manufacturer, the aircraft may not have been adequately tested for compliance with the ASTM standard for spin recovery.
Some flight schools had stopped doing stalls in them quite some time ago. I wonder how people managed to pass a licence test in one after telling the examiner that they were forbidden to stall it. That sounds criminal to me too.
