Yes. The minimum time on type is 10hours.
Fatboywings,
you will find CAO 82.1 Para 4 stipulates minimum experience on type for Charter operations on Multi-engine aircraft and SE Turbine aircraft. These requirements are 5 hours time on type for VFR ops and 10 hours time on type for IFR. If the aircraft was operating under AWAL "Adventure Flight" rules, I am not familiar with those to comment.
The above notwithstanding, you make some excellent points about the wider organisational factors that contributed to the accident. Good post.
