Antonov AN2? Bonkers, but it fits the description! Otherwise a turbo-prop caravan sounds about right.
It may well fit the description but it depends where to fly it. In the US? No way. The FAA has all but banned them to the airshow circuit. Reason, they don't want $15,000 competition for their industry.
I'd rephrase that to say FAA doesn't want competition to their
process of certification.
Factory built non-certified aircraft manufactured by US industry don't get non-restrictive operating limits in Experimental Exhibition category either. The only exceptions regardless of where the aircraft was made are Warbirds, Turbine aircraft (meaning jets for airshow display), or Aerobatic aircraft.
Interesting info on the An 2 anyway, its a neat aircraft. With 1000 Hp being used to move it at 100 knots, I wonder if you can actually feel the air in its wake being warmed up
