Since I have no time in a Cessna 421, I make no comment. How much time do you have in one?
How much time did the pilot in this crash have in the aircraft?
Gross weight and CG are killers if you lose one engine...so what were the numbers in this case?
I once bought an airplane and flew it 600 miles home in the dark only to find out that both probs would not feather.
And I will add that I bet 8 out of 10 421’s are operated by a single pilot.
My time is in Barons and Aztecs. The 421 is many times more expensive than a King Air depending on avionics and cabin interior. It’s a very fast unforgiving airplane. I worked at several airports on the general aviation side for about 30 years. I owned my own plane for 25 years.
