Two things: Firstly, anyone, no matter how experienced, will benefit from the Robinson Safety Course. I last did it with two high-time men, an Australian with 13,000 hours and a Brit with 12,000, and both told me they were taking a great deal away.
Secondly, number-crunching on single-engine helicopter accident statistics in the UK over the five year period 1995 to 2000 (soon to be published) has produced the following. R22 fatal accident rate: 1 per 115,213 hours. S300/H269 fatal rate: 1 per 30,939 hours. B206 fatal rate: 1 per 39,903 hours. MD500 fatal rate: 1 per 14,956 hours. AS350 rate: 1 per 62,741 hours. Considering the R22 did 46.46 percent of all civil single-engine flying in the UK during that period, and that a high proportion of that was in training details and by low-time pilots, I'm impressed.
