Juancho E. Yrausquin Airport is an airport on the Dutch Caribbean island of Saba. It is widely acknowledged as the smallest commercial airport in the world, with a runway length of 400 meters. (The absolute smallest is Simko Field Airport in Idaho, the United States at 122 meters, but it is not commercial.)
The airport, named after the Aruban Minister Juancho Irausquin, has the shortest commercial runway in the world, flanked on one side by high hills, with cliffs that drop into the sea at both ends. The airport is closed to jet traffic; only regional airline propeller aircraft are able to land there under waivers from The Netherlands Antilles' Civil Aviation Authority. The most common aircraft to land there are the STOL-capable de Havilland Canada DHC-6 Twin Otter and BN-2 Islander.
Jet aircraft are unable to land at the airport, because the runway is too short, but smaller STOL airplanes (such as the DHC-6, BN-2, and helicopters) are common sights. A small ramp and terminal are on the southwest flank of the runway. The ramp also has a designated helipad. The terminal building houses offices for Winair, immigration and security, a fire department with one fire truck, and a tower. The tower is an advisory service only and does not provide air traffic control. Aviation fuel is not available on the island of Saba.
