Rumour based on hearsay based on scaremongering based on speculative opinion.
If it was the same 182 with a cadet on night circuits that went in on a go-around, it was because of poor instrument flying go around ability. Also the flying school had a different go-around procedure promulgated in the company manual instead of the Cessna 182 manufacturer's POH procedure.
The CASA audit team missed that one?
