Landing Gear Configurations

Wherever your destination, the Twin Otter Series 400 has the landing gear(s) to get you there. In addition to standard wheel gear configuration, the Series 400 can be fitted with straight floats for dock-to-dock services, amphibious floats for dock to runway operations, wheel skis for snow-covered surfaces, and intermediate floatation gear for soft terrain and off-strip work. With these interchangeable gears, coupled with its short and rough field performance, the Series 400 is trusted by operators to take them where others cannot.
