Fitted with, Ram Air Recovery System, Short Field Enhancement, Dual Aft Body Strakes, Hartzell/Raisbeck Quiet Turbofan Propellor Kit with Auto Feather, Brake de-Ice System, Freon Air Conditioning, High Floatation landing gear...all as per their For Sale sheet on the net.
And, I note from the photo, the extended length gear doors. One common mod that is absent in this case is the wing lockers.
I doubt they would have HF radios - but I'm sure these would be installed at YMEN.
