True, but since those statements he has retracted some of his conclusions. For example, the number of fatal accidents SEL IMC is disproportionately high. But there aren't that many since few SEL airplanes are flying IMC at night.
And all it takes is one encounter, and you might say "To he77 with statistics!"
My small sample set includes one competent CFI who lost power over Nebraska IMC, at night -- hit the only tree in the state, and the airplane caught fire. He's alive, but not flying anymore. He has had numerous surgeries for extensive burns.
Another is a well-known, highly respected DPE that plowed a SEL into the side of a mountain in the Adirondacks. IMC, at night.
Another local DPE flying a deiced A36 collided with the ground a few miles short of the Cumberland Airport. IMC, at night.
I've flown SEL at night, but prefer not to. As i mentioned in another post, it's not just the pax I have to be concerned with, it's the people who will suffer if I'm not around -- wife, children, grandchildren, mother, father, siblings, and a who knows how many others...?
