Have you flown the 407 yet? You'll probably forget all
about trying to split hairs with statistics when you do.
Yes - did the Bell Academy Initial Pilot/Ground course about a year ago, some additional flying in the meantime, and am back at Bell soon for recurrent. The 407 is a fantastic machine IMHO, with only a few relatively minor things to complain about - the biggest one being the cramped cockpit relative to an A-Star or a 119 (both of which have other more significant issues).
If 46% of accidents are due to mechanical malfunctions, this doesnt seem like splitting hairs if an accurate reflection of real world experience.
