Interesting numbers Lu. Although I'm having trouble with translating the stats into reality.
The 206 is particular is an unreasonable comparison IMO.
First of all I would not class the 206 as a basic training helicopter, I can't imagine there is much flying done in those by novice / inexperienced pilots.
Secondly the B206 is known as the safest single engine aircraft (fixed and rotary). I think it's a bit much expecting a cheap piston basic trainer to match that.
More meaningful numbers would be comparative with other 2 seat trainers, both rotary and fixed wing. Even better if pilot failure and aircraft failure can be separated.
Anyone??
