Out of 60 K-Max's produced, 16 have crashed and been written off - that's 27% of the fleet! While admittedly this is a small production run that subsequently skews the numbers, I can't actually think of any aviation product of any kind that has suffered an attrition rate as high as this?
The K-Max remains an extremely popular helicopter and I know operators, pilots, and mechanics that love them, and have no qualms about operating them. This is the second time that production has been terminated, but maybe it'll come back again in the future. It was extremely successful as an autonomous unmanned platform, and it is hard to believe it won't reappear at some point in the future in that same role.
